4.4 Overtemperature protection mixing heating
circuit
This function is used to prevent the mixing heating circuit from reaching excessive
temperatures, caused by a defect of the mixing valve, for example.
The function is independent of the pump heating circuit’s overtemperature protection
and cannot be deactivated.
If the flow temperature exceeds the limit value “Maximum limitation of flow temperature”
+ 7.5 °C (fixed value), the pump will be deactivated.
This limit function acts only with the mixing heating circuit.
