4.7 HEAT RECOVERY EXCHANGER HYDRAULIC CONNECTIONS (OPTIONAL)
For all units equipped with a recovery condenser, the relative hydraulic circuit connections are male threaded
steel pipes (the diameter depends on the unit's size)
The units are equipped with a probe that monitors the temperature of the water returning from the system. The
microprocessor controller enables recovery when necessary, disconnecting the fans, and restarting regular operation
once the water has reached the desired temperature.
If faults occur on the recovery condenser the microprocessor controller restarts the fans.
The calibration values of the thermostat and pressure switches are given in the relevant controller instruction
manual.
For units equipped with a recovery condenser:
The water inlet and outlet must be connected to the recovery circuit in
the positions indicated as labelled on the unit.

It is mandatory to install a three-way modulating, valve with water tem-
perature probe, on the inlet to the unit to ensure that, at steady state
conditions, the inlet water temperature is not less than 30 °C.
