Air purge prerequisites
3 Install air purges on each part of the installation where the pipe work goes
down. (For example on a tank with connections on top.)
4 Fill the circuit to ±2 bar.
5 Purge all radiators and all other air purges installed on the circuit.
6 Repeat steps 2 and 3 until purging the radiators and the other points does NOT
longer lead to a pressure drop.
7 Make sure that the leaving water temperature home page, room temperature
home page, and domestic hot water home page are turned OFF.
When an air bubble blocks the pump and there is no flow, a 7H error can occur. In
this case, stop the air purge function and restart the operation. This will cause the
bubble to leave the pump. Make sure the pressure in the circuit is ±2 bar and refill
if necessary.
To check if the air purge function is finished, monitor the flow rate. If it stays
constant when the pump is running at high or low speed, the unit is properly
purged. To monitor the flow rate, go to [6.1.8].
The air purge function automatically stops after 42 minutes.
INFORMATION
For best results, air purge each loop separately.
Prerequisite: Make sure that the leaving water temperature home page, room
temperature home page, and domestic hot water home page are turned OFF.
