Fig. 4.5.1 Parameter window “X: Monitoring”
Parameter “Cyclic monitoring control value --in minutes (0...240 minutes) / --in seconds (0...59
seconds)”
These two parameters define the time that the relay monitors the telegram.
Generally speaking, the room thermostat will send the control telegram to the switch actuator at
specific intervals. If one or more of the consecutive telegram is omitted, this may indicate a
communications fault or a room thermostat malfunction.
During the set monitoring time, the switch actuator cannot receive the control telegram for the
thermostat; the output will switch to the fault mode and trigger a position during fault.
The fault mode ends as soon as a telegram is received as a control value. And the monitor time
will also be recounted when receiving the new control telegram. Options:
0...240 minutes
0...59 seconds
Note: if this function is activated, the room thermostat must periodically send out control
telegram. The monitoring time shall be greater than the interval time of control telegram sent by the
controller.
