P demand
1x050
The circulation pump in the master circuit can be controlled in relation to
the master circuit's demand or slave circuit's demand.
See Appendix “Parameter ID overview”
Heating applications:
OFF:
The circulation pump is ON when the desired flow
temperature in the heating circuit is higher than the
value set in 'P heat T'.
ON:
The circulation pump is ON when the desired flow
temperature from slaves is higher than the value set in
'P heat T'.
Cooling applications:
OFF:
The circulation pump is ON when the desired flow
temperature in the cooling circuit is lower than the value
set in 'P cool T'.
ON:
The circulation pump is ON when the desired flow
temperature from slaves is lower than the value set in
'P cool T'.
The circulation pump is always controlled according to frost protection
conditions.
MENU > Settings > Application
Ch.-o. valve / P (changeover valve / pump)
1x051
Choose whether the DHW heating control is based on a changeover valve
or a pump.
See Appendix “Parameter ID overview”
OFF:
Changeover valve
ON:
Pump
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.
A parallel option (heating and DHW heating in parallel) exists, based
on the setting ‘Parallel operation’.
MENU > Settings > Application
DHW priority (closed valve / normal operation)
1x052
The heating circuit can be closed when the controller acts as slave and when
DHW heating / charging is active in the master.
See Appendix “Parameter ID overview”
OFF:
The flow temperature control remains unchanged
during active DHW heating / charging in the master
controller.
ON:
The valve in the heating circuit is closed* during active
DHW heating / charging in the master controller.
* The desired flow temperature is set to the value set in
‘Frost pr. T’
This setting must be considered if this controller is a slave.
