P exercise (pump exercise) 11022<br />
Circuit Setting range Factory setting<br />
1 OFF / ON ON<br />
Exercises the pump to avoid blocking in periods without heat demand.<br />
OFF: The pump exercise is not active.<br />
ON: The pump is switched ON for 1 minute every third day at<br />
noon (12:14 hours).<br />
P frost T 11077<br />
Circuit Setting range Factory setting<br />
1 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) 11078<br />
Circuit Setting range Factory setting<br />
1 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 />
P post-run 11040<br />
Circuit Setting range Factory setting<br />
1 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. 11078)).<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 />
Frost pr. T (frost protection temperature) 11093<br />
Circuit Setting range Factory setting<br />
1 5 ... 40 °C 10 °C<br />
Set the desired flow temperature for example at heating cut-out, total stop<br />
etc. to protect the system against frost.<br />
5 ... 40: Desired frost protection temperature.<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 />
