This communication object is enabled if in
as is set with the option 1 bit.
The VAS/S receives ON or OFF telegrams from the thermostat.
Telegram value

This communication object is enabled if in
as is set with the option 1 byte.
The communication object value [0...255] determines the variable mark-to-space ratio of the valve drive. With
communication object value 0 the output switches OFF (valve is closed with normally closed valve drive). With
communication object value 255 the output switches ON permanently (valve is fully open with normally open valve drive).
Telegram value
11
If there is a fault on an output, e.g. due to a short circuit or an overload, the yellow LED of the corresponding output will flash
(5 Hz). At the same time, the communication object sends a telegram with the value 1. After the fault has been rectified with
the button
persists, the LED will flash again, and the communication object has the value 1.
As an alternative to button
with value 1.

This communication object is enabled if in
e.g. thermostat is parameterized with the option yes.
This communication object indicates a possible fault in the room thermostat. The communication objects Control value,
switch or Control value, continuous (PWM) can be cyclically monitored. Should the control value not be received by the
transmitting thermostat within a parameterizable time, a telegram with the value 1 is sent.
sent – depending on the parameterization – after a change and/or on request via the
values.

Control value, switch
Parameter window A:
0 = OFF
1 = ON
Control value, continuous (PWM)
Parameter window A:
0 = OFF (valve drive closed)
x = intermediate values
255 = ON (valve drive opened)
Overload/short circuit
, the fault is reset on the output concerned and the communication object has the value 0. If the fault still
, the fault can be reset via communication object Reset overload/short function by a telegram
0 = no overload/short circuit on the output
1 = overload/short circuit on the output
Fault control value
