3.2.5.1.1 Parameter window
A: Monitoring
In this parameter window, all settings for the function Monitoring are
undertaken.
This parameter is visible if in parameter window
, page 117, the
parameter Enable monitoring of the controller has been enabled.
Cyclic monitoring time of thermostat
in seconds (0…59)
Options: 0...59
in minutes (0…65,535)
Options: 0...60...65,535
The telegrams of the room thermostat are transferred to the electronic
actuator at specific intervals. If one or more of the consecutive telegrams are
omitted, this can indicate a communications fault or a malfunction in the
room thermostat.
If there are no telegrams received by the communication objects Switch or
Control value (PWM)
during the period defined in this parameter, the output
switches to fault mode and triggers a safety position. The fault mode is
ended as soon as a telegram is received as a control value.
Note
If this parameter window is visible, the room thermostat must send the
control value cyclically, otherwise no function monitoring is possible.
The monitoring time should be twice as long as the sending cycle time to
ensure that an error is not immediately signalled should the signal be
absent once.
