DHW priority (closed valve / normal operation) 12052<br />
Circuit Setting range Factory setting<br />
2 OFF / ON OFF<br />
The heating circuit can be closed when the controller acts as slave and when<br />
DHW heating / charging is active in the master.<br />
OFF: The flow temperature control remains unchanged<br />
during active DHW heating / charging in the master<br />
controller.<br />
ON: The valve in the heating circuit is closed* during active<br />
DHW heating / charging in the master controller.<br />
* The desired flow temperature is set to the value set in<br />
‘Frost pr. T’<br />
P frost T 12077<br />
Circuit Setting range Factory setting<br />
2 OFF / -10 ... 20 °C 2 °C<br />
When the outdoor temperature is below the set temperature in ‘P frost T’,<br />
the controller automatically switches ON the circulation pump to protect<br />
the system.<br />
OFF: No frost protection.<br />
-10 ... 20: The circulation pump is ON when the outdoor<br />
temperature is below the set value.<br />
P heat T (heat demand) 12078<br />
Circuit Setting range Factory setting<br />
2 5 ... 40 °C 20 °C<br />
When the desired flow temperature is above the set temperature in ‘P heat T’,<br />
the controller automatically switches ON the circulation pump.<br />
5 ... 40: The circulation pump is switched ON when the desired<br />
flow temperature is above the set value.<br />

Circuit Setting range Factory setting<br />
2 0 ... 99 m 3 m<br />
The circulation pump in the heating circuit can be ON for a number of<br />
minutes (m) after heating stop (the desired flow temperature gets lower<br />
than the setting in 'P heat T' (ID no. 12078)).<br />
This function can utilize the remaining heat in e.g. a heat exchanger.<br />
0: The circulation pump stops immediately after the<br />
heating stop.<br />
1 ... 99: The circulation pump is ON for the set time after the<br />
heating stop.<br />
This setting must be considered if this controller is a slave.<br />
Under normal conditions, your system is not frost protected if your<br />
setting is below 0 °C or OFF.<br />
For water-based systems, a setting of 2 °C is recommended.<br />
The valve is fully closed as long as the pump is not switched on.<br />
