Introduction​

What is SOL-LED+​

SOL-LED+ is a professional photoperiod regulator designed for the automatic management of LED lighting systems powered by very low direct voltage.

The device allows you to simulate in a natural way:

  • dawn
  • day
  • sunset
  • night light

The automatic management of the photoperiod allows you to reproduce seasonal variations in the duration of light during the year.

What is photoperiod for​

A dawn-dusk control unit is used to automatically manage the lighting of the farm. Regulates switching on, off and light intensity progressively, avoiding sudden transitions between darkness and full light.

In ornithology, regular management of daylight hours can help accompany rest, moulting, preparation for reproduction and singing, always respecting the biological needs of the animals.

For those who breed live decoys, the gradual control of the light-dark cycle allows you to simulate the seasonal trend in a closed room and prepare the animals for the hunting period with more natural transitions. Use must always comply with current regulations and correct animal husbandry and welfare practices.

Main features​

  • Two rooms with separate programs and parameters
  • Progressive simulation of sunrise and sunset
  • Annual automatic programs
  • Personalized programming
  • AstroGPS mode
  • 1 room or 2 rooms mode
  • Night light
  • Energy saving
  • Night inspection
  • Permanent storage of settings
  • Multilingual interface

Room management​

SOL-LED+ manages two programmable outputs.

From the device menu you can choose the method of use:

  • 2 rooms: the two outputs work as independent rooms;
  • 1 room: the second output follows the first, useful when you want to drive the same environment with both outputs, for example to distribute the power on two groups of LEDs.

In 2 rooms mode, each room can use:

  • different programs
  • different settings
  • different program times
  • different configurations

The two rooms share the same internal clock.

Operating philosophy​

SOL-LED+ was designed to simplify photoperiod management.

The user can choose between:

  • automatic programs
  • personalized programs
  • astronomical mode based on GPS coordinates

Once the initial configuration is completed, the device automatically manages the daily changes.

Applications​

SOL-LED+ can be used in all environments where it is necessary to automatically control the photoperiod using LED lighting.

Examples:

  • breeding
  • maintenance
  • reproduction
  • greenhouses
  • controlled environments
  • experimental applications

Control panel​

The main buttons are MENU, OK, directional arrows and INSP. for night inspection.

The front lights indicate the room reference 1, the room 2 and the status of the night inspection N.I..

To recognize the connection codes, consult the chapter Panel, Indicators and Terminals.

Power supply 12-24 V DC​

SOL-LED+ does not connect directly to the mains. The 230 V AC network powers an external stabilized power supply; only the 12-24 V DC output of the power supply needs to reach IN-POWER.

Power supply diagram SOL-LED Plus via external 12 or 24 V DC power supply
ClampFunction
+positive power supply 12-24 V DC
-negative power supply

The power supply must be stabilized and sized on the sum of the current absorbed by all the outputs used. For large systems it is advisable to work on 24 V with 24 V LED bars: with the same current it is possible to power a greater quantity of bars.

4-wire Season Generator PRO outputs​

OUT-SG-1 follows the program of stanza 1; OUT-SG-2 follows the room 2 program. These outputs are dedicated to the 4-wire Season Generator PRO rods.

Bblueblue LED channel / night light100 mA max
Cwhitemain PWM reference10 mA max
-blackcommon negative / GND2,5 A max

The bars connect one after the other with the in-out system. The arrangement is a chain from a mechanical point of view, but all the bars of the same channel remain electrically in parallel. Total absorption must not exceed 2,5 A per output.

2-Wire Commercial LED Outputs​

OUT-1 follows the program of stanza 1; The OUT-2 follows the room 2 program. These outputs power two-wire 12-24 V DC commercial LED bars or strips.

In-out connection of two-wire commercial LED bars to the two rooms
ClampTypical Conductor ColorFunctionLimit
+redpositive LED bar power supply2,5 A max
-blackcommon negative2,5 A max

Also in this case the bars can be connected in-out, as long as they remain electrically in parallel. Do not connect external drivers, 230 V lamps, or inductive loads to the LED outputs.

Difference between 2 and 4 wire bars​

Electrical difference between a two-wire LED bar and a four-wire Season Generator PRO bar

The two-wire rod receives positive and negative directly. The Season Generator PRO bar instead contains a driver and receives power, command for the blue LED, main PWM reference and ground.

Do not interchange the two types of output: the Season Generator PRO bars must be connected to OUT-SG, while the two-wire commercial bars must be connected to OUT.

Optional accessories OPT-OUT​

The OPT-OUT clamp brings together the remote night inspection button and the two brightness sensors.

Connection of the remote inspection button and the S1 and S2 brightness sensors
  • N.I.: remote button in parallel to the button on the panel;
  • S1: room brightness sensor 1;
  • S2: room brightness sensor 2;
  • GND: common of the three signals.

The button must be a simple dry contact. Use only compatible sensors and do not apply external voltages to the N.I., S1, S2 or GND.

Releases K-1 and K-2​

The K-1 and K-2 outputs exclusively control low direct voltage relay coils. They are not power contacts and must not directly power neon lights, lamps or the mains.

The voltage follows that of IN-POWER: with power supply to 12 V DC a coil is needed at 12 V DC; with power supply to 24 V DC you need a coil to 24 V DC. Maximum current is 100 mA per output.

The complete connection diagram is shown in the Relay chapter.

With MENU, from the Use Program screen, you go to the next screen of the main menu.

Program list​

The available programs are:

The names of the preloaded tables should not be interpreted as an exclusive restriction to the indicated species. They are practical names assigned to different light profiles: each table has its own seasonal trend, with minimum and maximum length of the day, growth and reduction of hours, sunrise and sunset times and ramp progression. For this reason, a table called, for example, Song thrush, REDWING, Fieldfare, Canaries or Crest Agi can also be used in different situations, when the light profile better corresponds to the objective of the farmer or user.

The programs listed can be selected directly from the Prg: menu.

Program Manual​

The Manual program uses fixed times set by the user. It does not apply daily increments and does not use an annual table.

When you confirm Prg: Manual, the display shows the sequence:

  1. Sunrise begin
  2. Sunset begin
  3. Sunrise duration
  4. Sunset duration

Use Manual when you want to keep the same on and off times every day.

Programs with preloaded table​

Programs with a preloaded table use sunrise and sunset values already stored in the device.

On the Season Generator website it is possible to see the behavior of the main tables and the times they represent day by day:

To advance or postpone the times in the table compared to those displayed, simply move the programmer date forwards or backwards. In this way the table also moves automatically and the user can adapt the period of greatest light to their needs.

For these programs the control unit calculates the daily times from the preloaded table and allows you to configure:

  • Sunrise duration
  • Sunset duration

Both parameters are expressed in minutes and have real limits:

  • minimum: 1
  • maximum: 100

Program Personal​

The Personal program does not use a default annual table. The user sets initial times and daily variations.

When you confirm Prg: Personal, the display shows the sequence:

  2. absolute final day;
  3. current RTC day;
  4. position of the current day between start and end;
  5. Sunrise and sunset interpolated between the initial and final values, rounded to the nearest minute.

If the device date is before the beginning, the control unit uses the first day. If the date exceeds the end date, use the end values.

The result is limited between 00:00 and 23:59.In the total light information screens, the device also adds Sunset duration to the time between sunrise and sunset. The total displayed is limited to 23:59.

Default values​

When reloading the default parameters, the control unit sets:

  • start date: 01/01/2026;
  • initial dawn: 08:00;
  • initial sunset: 18:00;
  • end date: 31/12/2026;
  • final dawn: 07:30;
  • final sunset: 19:00.

These values ​​are internal defaults and can be changed by user programming.

AstroGPS​

Introduction​

On the display the astronomical mode is shown as AstroGPS Timer.

AstroGPS Timer calculates daily times using:

  • coordinates of Controller place;
  • offset UTC: of Controller place;
  • coordinates of Simulated place;
  • status of the Twilight: parameter.

Times are recalculated based on the RTC date.

The coordinates are divided into two groups:

  • Controller place: real position of the control unit, used to locate the local solar noon;
  • Simulated place: position to simulate, used to obtain day length and twilight duration.

  • UP increases by 15 minutes;
  • DOWN decreases by 15 minutes;
  • ENTER confirm and move to Simulated place / Lat:.

Simulated place​

The second part of the configuration sets the location to simulate.

Screens displayed:

  1. Simulated place / Lat:
  2. Simulated place / Long:

The limits and commands are the same as Lat: and Long: of Controller place.

In the calculation, the control unit obtains the length of the day and the duration of the twilight periods from the Simulated place. These durations are then centered on solar noon calculated by the Controller place.

The display does not expose a separate UTC: parameter for the Simulated place.

Twilight:The Twilight: screen allows you to enable or disable the use of twilight.​

Actual display values:

  • Enabled
  • Disabled

Real commands:

  • UP toggles the value;
  • DOWN toggles the value;
  • ENTER save and return to the main page.

When Twilight: is confirmed, the control unit uses civil twilight.

If Twilight: is disabled, the device does not use the Start Crack and End Crack traits: the start of light coincides with Sunrise and the end of light with Sunset. Base ramps start at 1 minute, while Astro transition maintains the variation for 30 minutes after Sunrise and 30 minutes before Sunset.

If Twilight: is enabled, the device uses the onset of civil twilight as the onset of sunrise and ramps up to the calculated sunrise.

Type of twilight​

In this revision the user menu manages civil twilight.

There is no user choice between nautical or astronomical twilight.

Real ramp behavior AstroGPS​

With Twilight: enabled, the control unit:

  1. calculate sunrise and sunset of Controller place;
  2. obtains local solar noon from Controller place;
  3. calculate day duration and twilight duration of the Simulated place;
  4. centers the duration of the simulated day on the local noon of the control unit;
  5. calculate Crack Start, Sunrise, Sunset and Crack End;
  6. bring the light from 0 to the twilight level between Iniz Crep and Dawn;
  7. brings the light from twilight level to maximum level in the 30 minutes following Dawn;
  8. maintains the maximum level during the day;
  9. reduces light in the 30 minutes before Sunset;
  10. Bring the light from the twilight level to 0 between Sunset and End Crep.

With Twilight: disabled, the control unit uses dawn and dusk without extending the ramps to dusk; 30 minute Astro transitions around sunrise and sunset remain.

On the main page, when the active program is AstroGPS Timer, the display also shows dedicated information screens:

  • Sunrise / Sunset;
  • Start Crack / End Crack;
  • Total light hr / Today.

Default values​

When reloading the default parameters, the control unit sets:

  • Controller place latitude: 28.29;
  • Controller place longitude: -16.63;
  • Controller place UTC offset: 0;
  • Simulated place latitude: 28.29;
  • Simulated place longitude: -16.63;
  • twilight type: Civil;
  • Twilight: enabled.

Negative longitude is displayed as West.

An initial configuration may include room 1 on AstroGPS Timer, Controller place set to the actual installation position and Simulated place set to the place whose light cycle you want to reproduce.

Maximum intensity and brightness​

Introduction​

On the display the function is shown as:

  • Intensity'

This feature limits the maximum level reached by the main active room light.

The seasonal mode allows you to automatically vary, over the course of the season, not only the duration of the photoperiod but also the maximum intensity of the lighting.

In nature, the change of seasons does not only affect the hours of light: in periods with shorter days the light intensity can also be lower than in periods with long days and there is greater lighting.

By setting a minimum value and a maximum value, the control unit calculates the most suitable limit day by day. The variation occurs progressively together with the light program, without sudden changes.

On the display the item to search for is Intensity'.

Actual menu path​

Route:

MENU -> Intensity'

In the real menu loop, Intensity' comes after Use Program and before Room relay.

The first screen allows you to choose:

  • Fixed
  • Seasonal

With UP or DOWN you switch from one mode to the other. With ENTER you enter the values ​​of the chosen mode.

Fixed mode​

In Fixed mode, the controller uses only one maximum limit.

Displayed screen:

  • Intensity'

Real values:

ParameterValue
Minimum10 %
Maximum100 %
Default value80 %

Real commands:

  • UP increases the value;
  • DOWN decreases the value;
  • ENTER save and return to the main page;
  • MENU moves to the next menu item.

Seasonal mode​

In Seasonal mode, the controller automatically calculates the day limit using the photoperiod of the active program.

Screens displayed:

  1. Mini season
  2. Max season

Real values:

ParameterValue
Mid season10 % - 100 %
Max season10 % - 100 %

Min season cannot exceed Max season. If the maximum is lowered below the minimum, the control unit automatically lowers the minimum as well.

The control unit uses values ​​closer to Min season in periods with a shorter photoperiod and values ​​closer to Max season in periods with a longer photoperiod.

Example:

  • minimum period: 40 %;
  • maximum period: 100 %.

During the growing phase of the season, the maximum value gradually increases day by day. During the decreasing phase, the process occurs in reverse.

Information screens​

When the Seasonal mode is active and the program allows profile calculation, the following may appear on the main page:

  • PWM start
  • PWM today
  • PWM end

These screens indicate the level calculated at the beginning of the profile, the level of the current day and the final level.

Effect on operation​

Intensity' does not change sunrise and sunset times.

The control unit calculates the light ramp of the active program and then limits the main light level to the value allowed by the chosen mode.

If for a certain day the calculated value is 65 %, during dawn the light will progressively rise up to 65 %. During the period of full light it will remain at that level and, at sunset, it will gradually decrease from that value.

Example in Fixed mode:

  • active program at 100 %;
  • Intensity' set to 80 %;
  • main light output limited to 80 %.

Use with 1 room​

With Room use -> 1 room, room 2 copies the level of room 1. In this mode the operating limit to be considered is that of room 1.

Relay​

Introduction​

SOL-LED+ was created above all to control the LED bars installed near the cages. These bars allow you to create dawn, daylight, dusk and night light in a gradual and localized way.

In some environments, however, the bars near the cages are not enough to completely illuminate the room. It may therefore be useful to also turn on one or more neon lights, ceiling lights or other lamps intended for the general lighting of the room.

The K-1 and K-2 outputs allow this result to be obtained via an external relay:

  • K-1 follows the main light of room 1;
  • K-2 follows the main light of room 2;
  • each output powers only the low voltage coil of its own relay;
  • the power contacts of the relay turn the neon lights or lamps in the room on and off.

In this way SOL-LED+ continues to adjust the LED bars for smooth transitions and, when the light has reached the set level, it can also automatically turn on the general lighting.

On the display, relay management is shown with the screens:

  • Room relay
  • Relay PWM ON

The relay is managed separately for each room.

Actual menu path​

Route:

MENU -> Room relay

In the real menu loop, Room relay comes after Intensity' and before Energy Saving.

Screens displayed:

  1. Room relay
  2. Relay PWM ON

Room relay​

Enable or disable the active room relay.

Actual display values:

  • YES
  • NO

Real commands:

  • UP sets YES;
  • DOWN sets NO;
  • ENTER confirms.

If Room relay is NO, the relay remains off.

If Room relay is YES, the display changes to the Relay PWM ON screen.

Relay PWM ON​

Sets the percentage threshold of the main light PWM at which the relay must activate.

Real limits:

  • minimum: 0 %
  • maximum: 100 %

Default value:

  • 80 %

Real commands:

  • UP increases the value;
  • DOWN decreases the value;
  • ENTER save and return to the main page.

Real behavior of the relay​

The relay does not use a dedicated time slot.

The control unit calculates the PWM of the main light in the room and then:

  • if Room relay is NO, forces the relay off;
  • if there is a ALLARME_NTC thermal alarm, forces the relay off;
  • if Room relay is YES and the PWM percentage is greater than or equal to Relay PWM ON, turns on the relay;
  • if the PWM percentage is less than Relay PWM ON, it turns off the relay.

The firmware uses a single configurable threshold: the relay turns on when Relay PWM ON is reached and turns off when the value falls below the same threshold. There is no second switch-off threshold.

The threshold is compared to the PWM of the main light, not to the Night Light.

In Room use -> 1 room mode, the room 2 relay follows the calculated state for room 1.

Practical example with 80% threshold​

Suppose we set Relay PWM ON to 80 %.

  1. At the beginning of dawn the LED bars light up at low intensity and gradually increase.
  2. As long as the main light remains under the 80 %, the relay remains open and the neon remains off.
  3. When the ramp reaches 80 %, SOL-LED+ energizes the relay coil.
  4. The relay closes the power contacts and turns on the neon or lamps that illuminate the room.5. During sunset the reverse process occurs: when the light drops below the 80 %, the coil is de-powered, the contacts open and the general lighting turns off.

The LED bars can thus continue the final part of the sunset on their own, avoiding the sudden switching off of all the lights in the room.

Relay coil connection​

The K-1 and K-2 outputs are not power contacts. They are low voltage DC outputs to power the coil of an external relay, with a maximum current of 100 mA per output.

The available voltage is the same as the device power supply:

  • power supply SOL-LED+ to 12 V DC: use a 12 V DC relay coil;
  • power supply SOL-LED+ to 24 V DC: use a 24 V DC relay coil.
Control diagram of the relay coils K-1 and K-2 of the SOL-LED Plus

The relay has two electrically separated parts:

  • control side: the coil to 12 V DC or 24 V DC, connected to K-1 or K-2;
  • power side: the contacts that connect and disconnect the power supply of the neon, ceiling light or lamps.

The diagram shows an example with an external bipolar relay. On the power side, a cable with plug carries the power from the mains socket to the relay contacts; a second cable comes out of the contacts and reaches the neon or the lamps in the room. When the coil is energized, the normally open contacts close and the load turns on.

The chosen relay must have:

  • coil with the same supply voltage as SOL-LED+;
  • coil absorption not exceeding 100 mA;
  • contacts sized for voltage, current and type of connected load;
  • suitable insulation between low voltage coil and mains contacts.

The final load must be connected to the external relay contacts, not directly to K-1 or K-2. Connections to the electrical network must be carried out by qualified personnel.

Separate low voltage and mains electricity

Never connect the 230 V AC mains to the K-1 or K-2 terminals. These terminals power exclusively the low voltage coil of the relay. Plug, mains cable, power contacts and neon connection must be made and protected according to the regulations of the electrical system.

Effect during sunrise and sunset​

During the dawn ramp, the PWM increases progressively. The relay activates when the ramp reaches the Relay PWM ON threshold.

During the sunset ramp, the PWM progressively decreases. The relay deactivates when the ramp drops below the Relay PWM ON threshold.

Compatibility with programs​

The behavior of the relay depends on the PWM generated by the active program.

It is therefore applicable with:

  • Manual
  • Personal
  • Custom2
  • AstroGPS Timer
  • internal tables like Standard, Song thrush, REDWING, Skylark, Fieldfare, Breeding, Finches, Canaries, Crest Agi

Night Light​

What is it for​

The Night Light function automatically maintains a very low brightness when the daily program enters the night phase.

It can be useful when you don't want to leave the environment completely dark and want to maintain a weak light reference. It must not transform the night into a full light phase: normally a low value is set, sufficient for the purpose but clearly distinct from daylight.

On compatible Season Generator PRO bars the function uses the channel dedicated to the night light. The adjustment is separate from the main light and is managed automatically by the room program.

On the display the function is shown as Night Light.

Actual menu path​

Route:

MENU -> Night Light

In the real menu loop, Night Light comes after Energy Saving and before Inspection time.

Displayed screen:

  • Night Light

Configurable parameter​

The screen shows:

  • OFF, if the value is 0;
  • a percentage, if the value is greater than 0.

Real limits:

  • minimum: 0 % (OFF)
  • maximum: 50 %

Default value:

  • 0 % (OFF)

Real commands:

  • UP increases the value;
  • DOWN decreases the value;
  • ENTER save and return to the main page;
  • MENU goes to the Inspection time screen.

Real behavior​

The controller calculates the maximum room level from Intensity' and then calculates Night Light as a percentage of that level.

During the day the main light prevails. When the main light is at zero, the controller can gradually raise the night light to the set level. When the next daytime phase starts, the device manages the transition from night light to the normal dawn ramp.

If the value is OFF, at the end of sunset the room is brought to the darkness foreseen by the program.

Practical example​

With Intensity' set to 80 % and Night Light to 10 %, the nighttime level is taken from the maximum configured for that room. Changing the maximum intensity therefore also changes the actual level of the night light.

Always start from low values ​​and observe the real result in the environment. Increase the value only if the light reference is not sufficient.

Difference from night inspection​

The Night Light is automatic and can remain active throughout the night phase foreseen by the program.

The Night Inspection, on the other hand, is a temporary command used to enter the room and see for the time necessary for the visit. At the end it must be deactivated to return control to the main program.

Interaction with Energy Saving​

The Night Light is inhibited when the device activates the shutdown conditions related to energy saving.

In particular, when energy saving requires shutdown, the night ramp is reduced.

Interaction with alarms​

If the device detects thermal lockout or invalid current offset, the PWM outputs are forced to zero. In this condition the Night Light is also turned off.

Night inspection​

Introduction​

The night inspection is used to enter the room when the light is off and make a short visit while disturbing the birds as little as possible.

By pressing the dedicated button (I or INSP., according to the panel graphics) the control unit starts a quick little dawn: the light gradually rises instead of turning on suddenly.

When the light has reached sufficient intensity to see inside the room, press the inspection button again. In this way the level is blocked at the point reached, without causing the light to rise further.

If the button is not pressed a second time, the inspection continues to increase to the level required by the configuration.

If the relay is enabled for the room and the inspection ramp reaches the Relay PWM ON threshold, SOL-LED+ can also power K-1 or K-2 and turn on the neon or general lighting connected to the external relay. By pressing the button before reaching the threshold, the light is blocked at the level sufficient for the visit, without needlessly turning on the entire room.

At the end of the visit, press the inspection button again to exit. The light must go off: only then does SOL-LED+ return to the main program. If the inspection remains active, the light can remain on and the normal day-night cycle is excluded.

The inspection configuration uses three menu parameters:

  • Inspection time
  • Inspection time
  • Night insp.sel

Actual menu path​

Route:

MENU -> Inspection time

In the real menu loop, the inspection setup comes after Night Light and before Modify / Date / Time.

Screens displayed:

  1. Inspection time
  2. Inspection time
  3. Night insp.sel

Inspection time​

Set the duration of the inspection input ramp.

Real limits:

  • minimum: 1 minute
  • maximum: 100 minutes

Real commands:

  • UP increases the value;
  • DOWN decreases the value;
  • ENTER confirm and move to Inspection time.

Inspection time​

Set the duration of the inspection exit ramp.

Real limits:

  • minimum: 1 minute
  • maximum: 100 minutes

Real commands:

  • UP increases the value;
  • DOWN decreases the value;
  • ENTER confirm and move to Night insp.sel.

Night insp.sel​

Select which rooms the night inspection is active on.

Actual display values:

  • room 1
  • room 2
  • room 1+2

Real limits:

  • minimum value: room 1
  • maximum value: room 1+2

If the saved parameter is out of limit, the control unit returns it to room 1+2.

Activation with I button​

The function is not activated from the configuration menu.

Activation occurs with the inspection key I.

The I key cycles through three states:

  1. inspection off, light off;
  2. inspection active, light up and warning light on;
  3. light stuck at the level reached, indicator light flashing.

When the status is 1, the light in the selected room rises with the Inspection time ramp.

When the state returns to 0, the light ramps down Inspection time.

In practice, the flashing state corresponds to the manual blocking of the inspection light. Before leaving the area, always turn off the inspection light.

In Room use -> 1 room mode, the second exit also follows the inspection ramp of room 1.

Remote button​

The OPT-OUT - N.I. terminal carries the night inspection command externally.The OPT-OUT accessories diagram shows the location of the clamp and the connection of the remote button.

By connecting a normally open button between N.I. and GND, the user can activate the same function even far from the control unit, for example near the door or at the entrance to the room.

Season Generator can provide an optional kit to remote the button. Alternatively, where the product diagram requires it, it is possible to use a clean button contact, installed in a component of the electrical system: pressing that button gives the same effect as the button on the programmer.

The external button must be a clean contact: it must not carry external voltage on the N.I. terminal.

Energy Saving​

Introduction​

The Energy saving function allows you to reduce the consumption of the system by exploiting, when available, the natural light coming from outside.

The purpose is simple: if during some hours of the day the light entering through the windows already illuminates the room correctly, it is not necessary to keep the artificial lamps on.

SOL-LED+ can work in two ways:

  • timed, when the user already knows the period of the day in which the room receives enough natural light;
  • with sensor, when you want the control unit to decide based on the detected brightness.

At the end of the savings band, or when natural light is no longer sufficient, the control unit automatically returns to the management provided by the sunrise and sunset program.

On the display the function is shown with the screens:

  • Energy / Saving
  • Energy saving

The main parameter selects one of the modes available for the active room.

Actual menu path​

Route:

MENU -> Energy Saving

In the real menu loop, Energy Saving comes after Room relay and before Night Light.

Screens displayed:

  1. Energy / Saving
  2. Energy saving

Available modes​

The Energy saving screen shows one of the following values:

  • Disabled
  • No sensor
  • With sensor

The With sensor mode allows you to use the brightness sensors connected to the S1 and S2 terminals.

Real commands:

  • UP scrolls forward through modes;
  • DOWN scrolls back through modes;
  • ENTER confirm;
  • MENU switches to Night Light.

Disabled​

With Disabled, the control unit cancels the energy saving:

  • no scheduled shutdown;
  • no sensor intervention;
  • no night light inhibition linked to savings.

The light follows the selected program without energy saving interventions.

No sensor​

With No sensor, the control unit uses a shutdown time slot.

This mode is useful when the natural lighting in the room is predictable and fairly constant. For example, if the program predicts sunrise at 06:30 and sunset at 21:00, but between 11:00 and 14:00 the room is already lit by the windows, it is possible to use that period as an energy saving period.

Actual display values:

  • YES
  • NO

Real behavior:

  • NO: switching off and on again is immediate;
  • YES: switching off and on again follows the ramps.

During the configured interval the control unit turns off the light.

With sensor​

With With sensor, SOL-LED+ uses the active room's external light sensor.In this mode the control unit compares the detected brightness with the set threshold. When natural light is sufficient, artificial lighting can be turned off or reduced according to the chosen setting; when natural light decreases, the program resumes normal room management.

Links:

  • room 1: brightness sensor between S1 and GND;
  • room 2: brightness sensor between S2 and GND.

See the OPT-OUT accessories diagram to recognize the terminals and connect the two sensors.

The sensor must be positioned in the point where you want to measure natural light, for example near a window, but it must not be illuminated directly by the bars or other lamps controlled by SOL-LED+.

If the sensor receives artificial light from the same system it is supposed to control, the reading can become unstable: the control unit could turn off the light, immediately detect darkness and turn it back on repeatedly. Then position S1 and S2 so that they primarily represent the natural light available in their respective rooms.

Gradual:​

Actual display values:

  • YES
  • NO

Real behavior:

  • NO: switching off and on again is immediate;
  • YES: switching off and on again follows the ramps.

Real behavior with sensor​

When With sensor is active and Sensor limit is greater than zero, SOL-LED+ compares the detected brightness to the set threshold.

If the detected brightness exceeds Sensor limit, SOL-LED+ may turn off the main room light even if the program would be turned on. In this way natural light can temporarily replace artificial lighting.

If Sensitivity is greater than zero, the control unit uses a return threshold equal to:

Sensor limit - Sensitivity

When natural light drops below the return threshold, the system can turn back on following the program and the Gradual: setting.

The sensitivity avoids continuous switching on and off when the brightness is close to the threshold.

Use 1 room when you want to use a single program, but for power reasons it is better to connect two groups of LEDs to the two programmer outputs.

In this mode both outputs illuminate the same environment and follow the same photoperiod.

Use 2 rooms when the two environments must have different programs or parameters.

Can I change parameters during operation?​

Yes.Changes are applied immediately and stored automatically.

Is maintenance necessary?​

Normally, periodic maintenance is not required.

It is advisable to periodically check:

  • connections;
  • diet;
  • correct functioning of the system.

Where can I find the firmware version?​

The firmware version can be viewed on the device information screens.

Always note the firmware version before requesting technical assistance.
