Dimmer - Switch/push-button connected to input terminal SW1 (SW2)

Input modes

• Switch - allows making and breaking the connection in an electric circuit.

• Button - “single (short) press ”, “double press ” and “press and hold (long press) ” are supported

Output types

• Input set as “Switch”

  • Toggle - acts as a flip switch with one state for “ON” and one state for “OFF”

  • Edge - changes state on every change of the switch state

  • Detached - input is separated/not changing state of the output

• Input set as “Button”

  • Momentary - every press toggles the state of the output: ON -> OFF or OFF -> ON

  • Detached - input is separated/not changing state of the output

  • One button dim mode - press to toggle, press and hold to dim up/down (changes direction on each press and hold)

  • Dual button dim mode - 2 inputs configuration. First button dims up and the second one dims down.

Minimum Brightness on Toggle On (par 129, 130)

Minimum brightness on toggle is preset with value that is device specific (for more information see the technical specification of the device). Minimum brightness on toggle can be changed by the user to the desired level. It is applied on toggle on (Off ? On state change) when the Light brightness < min_brightness_on_toggle.

Note: the brightness should be lower then value defined by minimum ON value ref. to par129&130. With toggle ON the brightness will go to value defined by par129&130.

NOTE: par. 130 Valid only for Pro dimmer 2PM

Min/max brightness definition

Min/Max brightness reframes the range of the dimming signal to get more precise brightness control on the output.

Initially Min/max brightness is 0-100% which means the whole range will be used. Changing the values allows the users to use only the range that is suitable for their devices (led drivers, fans, etc.)

Once min/max brightness is set, any kind of calls to setting brightness would be remapped to the corresponding actual % internally, based on the range provided.

Button fade rate definition

Button fade rate controls how quickly the output brightness changes while holding (long press) the button(s).

Button fade rate is measured in %/s, for example, if 10% is set, on button press and hold the brightness will be changed from 0% to 100% for 10 seconds.

Single button dimming control

Single press (Short press)

Use to toggle On/Off - every press changes the state of the output.

A press is considered ‘single’ if the button is pressed and released within 0,5 second. (Short press)

• Light state: On -> Light state: Off - Turns the lights off and keeps the current brightness. Default transition is applied. Press between transition stops the dimming

• Light state: Off -> Light state: On. Press between transition stops the dimming

• Current brightness: < Minimum brightness on toggle value - Turns the lights on with brightness that is set in Minimum brightness on toggle. Default value is device specific

• Current brightness: > Minimum brightness on toggle value - Turns the light on with the brightness that was previously set

Double press

A press is considered ‘double’ if the button is pressed and released within 0,5 seconds, pressed and released again in less than 0,5 second and after that there is no other press.

• Light state: On->Double press - Sets brightness 100%

• Light state: Off->Double press- Turns the lights on with brightness 100%

Press and hold (Long press)

Use to dim up/down - every press changes the direction.

A press is considered ‘long’ if the button is pressed for more than 0,5s

• Light state: On

• Dim Up - starts dimming up from the current brightness with the specified fade rate.

• Dim Down - starts dimming down from the current brightness with the specified fade rate. 1% is the lowest possible brightness that can be set when dimming down.

• Light state: Off

When the light state is off, on press and hold the device starts to dim up. First the lights are turned on with 0% brightness and then are dimmed up with the specified fade rate.

Dual button dimming control

Single press (Short press)

SW1 dimming UP, press between dimming STOP, next press full ON (with SW1 you can’t turn OFF or dimming DOWN)

SW2 dimming DOWN, press between dimming STOP, next press OFF (with SW2 you can’t turn ON or dimming UP)

A press is considered ‘single’ if the button is pressed and released within 0,5 seconds

• Light state: On -> Light state: Off - Turns the lights off and keeps the current brightness. Default transition is used. Only by SW2!

• Light state: Off -> Light state: On. Only by SW1!

• Current brightness: 0% - Turns the lights on with brightness that is set in Minimum brightness on toggle. Default value is device specific, for more details see the corresponding technical specification. Only by SW1!

• Current brightness: >0% - Turns the lights on with the brightness that was previously set. If an action/night mode is active or minimum brightness on toggle is set, the corresponding brightness is applied (if needed). Default transition is used. Only by SW1!

In dual button dimming mode Double press is not working.

Press and hold (Long press)

Use to dim up/down - SW1 dimming up and SW2 dimming down.

A press is considered ‘long’ if the button is pressed more than 0,5 seconds

? Light state: On -> Dim Up - starts dimming up from the current brightness with the specified fade rate until released (SW1).

? Light state: On -> Dim Down - starts dimming down from the current brightness with the specified fade rate until released. 1% is the lowest possible brightness that can be set when dimming down (SW2).

? Light state: Off -> Dim Up - starts dimming up from the current brightness with the specified fade rate until released (SW1).

? Light state: Off -> Dim Down - nothing. No change in the brightness also.

Transition Duration

Implicit (default) transition

Implicit (default) transition is applied every time the brightness of the lights, controlled by the device, is changed.

• When the lights are turned on or off, transition time (in seconds) is the time to change from 0% to 100% of brightness on toggle On and from 100% to 0% brightness on toggle Off. ref. Parameter No. 124, 126 - Dimming time (soft on/off)

• When the lights are on, transition time (in seconds) is the time between change from current brightness level to desired brightness level. Note that if desired brightness level is 0%, this is considered “light off” (example: transition: 5 sec, light: on, current brightness: 50%. If the brightness is changed to 0%, transition time is 2.5 sec. If the brightness is changed to 1%, transition time is 5sec).

Implicit transition is preset with a value of 3 seconds and can be customized by the user with value between 0 and 5 seconds

NOTE: par. 126 Valid only for Pro dimmer 2PM
