If coil 2 is configured as Mixed, the action on its valve will be limited to prevent a drift in the temperature for the return network to
the heat pump.
If there is a fault with the heat pump (information received via a potential-free (dry) contact), an alarm will be displayed.

Plate recovery
A differential pressure switch is used to check the fouling level on the return side of the heat recovery unit and to manage the frost

This damper is also activated if there is a Free cooling request.

The aim is to use the same input ID1 to control either:
This control principle does not cause an alarm to be created.
