LAYOUT WITH 3-WAY VALVES
Units with sanitary hot water or recovery exchanger are equipped
with a temperature probe. The probe must be connected to the unit
as shown in the electrical diagram. The sensor of the probe should be
installed in a relative well in the boiler. The well should be at the top of
the boiler or at the point where the water in use is at its hottest. In order
to ensure efficient operation, it is necessary to put conductive paste in
the well to make the probe work correctly. Failure to observe the above
requirements can result in malfunctioning or triggering of the unit’s
safety devices.

WATER OUT
It is important that the water inlet of the recovery circuit is
installed where the connection is marked with the following plate:
It is mandatory to install a 3-way modulating valve with temperature
probe on the water entering the unit, which in normal working
conditions guarantees an input water temperature no less than 25 °C.
The safety devices can be triggered if the system that guarantees an
input water temperature no less than 25 °C.
