11
Trigger valve purge
Output A
EIS 1, 1 bit
DPT 1.001
C, W
This communication object is enabled if in parameter window A: Function
the parameter Enable function "valve purge" has been selected with the option yes.
The valve purge is triggered using this communication object.
Telegram value:
0 = end valve purge, valve will be closed
1 = start valve purge, valve will be opened
12
Status valve purge
Output A
EIS 1, 1 bit
DPT 1.002
C, T
This communication object is enabled if in parameter window A: Function
the parameter Enable function "valve purge" has been selected with the option yes.
The status of the valve purge is visible via this communication object.
Telegram value:
0 = valve purge not active
1 = valve purge active
Note
The status is displayed as soon as a purge has been activated.
The status remains active, even when the purge has been interrupted, e.g.
by a priority.
13
RTR fault
Output A
EIS 1, 1 bit
DPT 1.005
C, T
This communication object is enabled if in parameter window A: Function
the parameter Enable monitoring of the controller has been selected with the option yes.
Using this communication object, both communication objects Switch and Control value
(PWM)
can be cyclically monitored. If the values of the room thermostat (RTR) remain absent,
the device assumes that the thermostat has a malfunction and signals a fault.
Telegram value:
1 = fault
0 = no fault
14
Forced operation
Output A
1 bit (EIS 1)
DPT 1.003
C, W
This communication object is enabled if in parameter window A: Function
the parameter function "forced operation" has been selected with the option yes.
If the object receives the value 1, the valve is forcibly moved to the parameterised position,
which has been set in the parameter window A: Forced operation.
The forced positioning of the valve should remain until forced operation is ended. This is then
the case when a 0 is received via the communication object Forced operation.
Please note that the function Forced operation and a bus voltage failure have a higher priority
on the switching state, see
