This communication object is enabled if the parameter Monitoring control values e.g. thermostat has been selected with the
option Yes in
This communication object indicates a possible fault in conjunction with the room thermostat. The communication object
Control value, heating, ON/OFF or Control value, heating, continuous (PWM) can be monitored cyclically. If the control value
from the sending room thermostat remains missing for a parameterizable time, a telegram with the value 1 is sent.
The communication object value is sent via the communication object Request status values depending on the
parameterization, on a change and/or request.

This communication object is enabled with the option Yes via the parameter Enable valve purge in
Function.
Telegram value:
The purging cycle time is restarted if automatic valve purge has been activated at start-up of the device.
The purging cycle time will be restarted at the end of the actual purging period. The parameterized valve purging duration is
included here.
If a valve purge currently underway is interrupted by a manual valve purge or a control value, which reached the
parameterized purge value, the purge cycle time is restarted. If the active purge duration was less that the parameterized
purge duration, this will not be taken into consideration. In this case, the actual purge cycle time is shorter in duration by the
active purge duration.
