Controller auxiliary unit properties

• The controller auxiliary unit can be parametrised as the function of a rocker or button. Control of a room temperature controller (operating modes, presence function and setpoint adjustment).
• Evaluation of the controller status via status LED.
• Temperature measurement can be activated. Measurement of the room temperature with an internal sensor or optionally by creating a measured value of the internally measured temperature with an external temperature.

Functions of the status LEDs

• The function selection is made for each status LED. The following functions can be parametrised: always OFF, always ON, actuation display, telegram acknowledgement, status display, control with separate LED object, operating mode display, controller status display, presence status display and setpoint adjustment.
• Colour can be parametrised. The colour selection is performed either for all status LEDs or separately for each status LED of the device. The status LEDs can light up in red, green, blue, yellow, cyan, orange, violet or white as required.
• The status LEDs have six adjustable brightness levels. With night-time reduction, the brightness of the status LEDs can be reduced in the night hours by means of a communication object.
• In addition, a superordinate function can be enabled for every status LED, allowing another colour and display type to be set.
• Alarm message LED: All LEDs of the pushbutton sensor can flash red simultaneously in the event of an alarm message.
• LED orientation lighting: For orientation, all LEDs can be switched off or on permanently, indicate the status of a separate communication object (ON, OFF, flashing) or be switched on when a button is pressed and automatically switched off again after a delay time passes.
• LED traffic light function for indoor air quality (VOC).
