Dependent parameters:
Monitoring time
in s [30...65,535]
30...120...65,535
Options:
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.
