Secondary circuit (domestic hot water circuit)
The DHW circuit is affected every time it is necessary to take
the temperature of the water contained in the storage tank to
the desired temperature (2) and is measures using the DHW
NTC probe (9).
This can take place in the case of a domestic hot water with-
drawal or to restore the losses due to heat loss.
Operation.
Following a DHW request, the P.C.B. starts the boiler pump
(7) and powers the electric 3-way valve motor (8).
The consequent shifting of the valve into the DHW position
(see electric 3-way valve functioning) leads to the closure of the
system return pipe (R) and the simultaneous opening of the
passage towards the storage tank coil (4).
In this way circulation inside the CH system is prevented,
while it is allowed in the coil (4) which, allows the cold water
to absorb the heat contained in the primary circuit water
through its walls.
The CH phase is excluded in this phase over which the pro-
duction of DHW has priority.
