7.2 Application

Ch.-o. valve / P (changeover valve / pump)
Circuit
3
Choose whether the DHW heating control is based on a changeover valve
or a pump.
OFF: Changeover valve
ON: Pump
Tank, sec. / prim.
Circuit
3
Choose whether the heating of the DHW tank is dependent on the flow
temperature at S3.
OFF:
The DHW tank is heated by means of the S3 temperature.
ON:
The DHW tank is heated separately. The S3 temperature
has no influence on the DHW heating.
DHW P post-run
Circuit
3
Set the DHW pump (P3) post-run time (minutes). The DHW pump can
continue to be switched ON after the DHW heating procedure in order to
utilize the remaining heat in the heat exchanger / boiler.
0 ... 30: Set the number of minutes for the post-run.
Send desired T
Circuit
3
When the controller acts as a slave controller in a master / slave system,
information about the desired flow temperature can be sent to the master
controller via the ECL 485 bus.
OFF:
Information about the desired flow temperature is not
sent to the master controller.
ON: Information about the desired flow temperature is sent
to the master controller.
Frost pr. T (frost protection temperature)
Circuit
3
Set the desired flow temperature to protect the DHW system against frost.
5 ... 40: Desired frost protection temperature.

When the changeover valve is chosen, pump P1 is ON at heating as
well as at DHW heating demand.
When the pump is chosen, pump P1 is ON at heating and OFF at DHW
heating demand.
In the master controller, 'Demand offset' must be set to a value in order
to react on a desired flow temperature from a slave controller.
