No. Functionality communication object name Data type Flags
12 Fault control value Output A
Output A/B
1 bit
DPT 1.005
C, R, T
This communication object is enabled if the parameter Monitoring control values e.g. thermostat has been selected with the
option Yes in Parameter window A: Output (Valve drive, thermoelectric (PWM)) , p. 97.
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.
Telegram value: 0 = No fault
1 = Fault
13 Activate purge Output A
Output A/B
1 bit
DPT 1.003
C, W
This communication object is enabled with the option Yes via the parameter Enable valve purge in Parameter window
Function . p. 113. 'The valve purge is enabled via this communication object.
Telegram value: 0 = End valve purge, valve will be closed
1 = Start valve purge, valve will be opened
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.
Note
A valve purge not undertaken due to a higher priority will no longer be undertaken.
The following functions are executed with telegram value 0.

A valve purge currently under way is interrupted.

The purge cycle with automatic valve purging will be restarted.
