Valve is
Options: Heating valve
Cooling valve
This parameter determines whether the valve is defined as a heating valve or cooling valve.
Monitoring control values
e.g. thermostat
Options: No
Yes
This parameter is activated for monitoring cyclic sending of the control value, e.g. of the room thermostat.
The reaction to the absence of a control value is defined in monitoring of the control value. This ensures
emergency operation.

Yes: The communication object Control value , p. 211, is enabled.
Dependent parameters:
Monitoring time
in s [30…65,535]
Options:
30…120…65,535
This parameter sets the time used to monitor the telegrams on the input control values:
communication objects
Control value, ON/OFF , if the option Bit has been selected for the
parameter Control value is received as , or Control value, continuous (PWM) 1 , if the option Byte
has been selected for the parameter Control value is received as .
If a control value is not received within the parameterized time, a malfunction or a defective room
thermostat is the cause.
The reaction of the output to a control value not received can be defined in the following
parameters.
Send object value "Control value fault"
Options: No, update only
On change
After request
After a change or request

No, update only : The object value is updated but not sent.

On change : The object value is sent when a change occurs.

After request : The object value is sent when a request occurs.

After a change or request : The object value is sent when a change or request occurs.
