The 30AWH units drive a 3-way valve to manage a sanitary water
accumulation tank. The operating logic provides that, in the
case of a request for sanitary water by an accumulation tank, the
system controls a 3-way valve to direct the hot water only to the
tank and to operate at the maximum capacity to provide water at
60 °C (compatible with the operating envelope).

The sanitary water request signal must be a Dry Contact type
(contact quality greater than 25mA @ 12V) that closes the circuit

Attention: The sanitary water request has higher priority than
the programmed operating mode in both heating and cooling
mode.
To force the unit to operate at a lower maximum frequency
(to reduce noise) in the absence of a User Comfort Interface,
provide a Dry Contact (contact quality greater than

with a maximum frequency lower than the standard one,
There are several signals available on the terminal strip to indicate
particular conditions or the stop of the external unit.
