Push-button, 4-gang plus with room temperature control unit and IR receiver

Multifunction with RTCU and FanCoil 1817/1.0

Display external temperature in display

You can cyclically read an external temperature value

(2-byte value) via the bus and display it. The external

temperature can be the outdoor temperature transmit-

ted from a weather station, for example.

The external temperature is only shown in the dis-

play, this temperature has no effect on the control

behaviour of the push-button.

Communication objects

You can select the following communication objects:

You can use this setting in combination with the Fan Coil

actuator, for example. If you combine it with the "Linear

regulator" push-button function, you can easily control

fan speeds with one push-button.
The display can be used to show whether the fan of the

fan coil actuator is working in automatic or manual

mode and which fan speed is currently activated. The

status feedback object can be used to send the status

to the LED.
In the parameters, you can set the percentage values at

which the individual levels are displayed.
