Instructions for replacing pumps:
- Close ball valves in FL and RL before pump upgrade and depressurise system
- Please note: some water will inevitably escape when replacing the pump.
Bypass position:
A bypass is integrated into the mixer, which is closed in its delivered state (see Fig. 2.1).
The bypass can be opened steplessly (see Fig. 2.2).
It makes sense to open the bypass when the heat generator temperature level provided is always much
higher/lower than the required temperature in the heating circuit. For example, the continuous mixing of
cold return water lowers the supply temperature of the heating circuit. The adjustment travel of the mixer
is greater to enable the servomotor to make more accurate adjustments.
1. Heating/cooling system must be in normal operation (high boiler temperature, recirculation pump on)
2. Open the bypass to 100%
3. Set the mixer to position A) = no mixing on the return line side
4. Close the bypass very slowly until the maximum or minimum flow line temperature is reached in the
heating/cooling circuit
