Project design and programming
This parameter window is visible if the value "yes" has been entered in the
parameter Enable monitoring of the controller in the parameter window "x:
Function".
Parameter: "Cyclic monitoring time of room thermostat"
The telegrams of the room thermostat are transferred to the electronic
actuator at specific intervals. If one or more of the subsequent telegrams is
omitted, this can indicate a communications fault or a defect in the room
thermostat. If there are no telegrams to the objects "Switch" or "Control value
(PWM)" during the period defined in this parameter, the actuator switches to
fault mode and triggers a safety position. The fault mode is ended as soon
as a telegram is received.
Note: If this parameter window is visible, the room thermostat must
send the control value cyclically, otherwise no function is
possible. The monitoring time should be greater than the cyclic
transmission time (recommended: Factor 2).
Parameter:
"Position of the valve drive during fault of room thermostat"
The safety position which is triggered by the actuator in fault mode is defined
here. The switch cycle time t
"PWM cycle time for continuous control".
Parameter: "Enable object 'Telegr. fault'"
The object "Telegr. fault thermostat" which can display the failure of the
room thermostat can be enabled in this parameter.
of the control is defined in the parameter
