Scheme 01:
the boiler/thermostove is connected to a domestic hot water tank and to the heating cir
cuit.
During the “WINTER” mode the boiler/thermostove is switched of
f when the contact (thermostat) below is satisfied. The boiler/thermostove is
switched on when the contact (thermostat) detects a temperatur
e below SET ACS - ΔT (ΔT can be set by technical parameters).
By setting the “SUMMER” mode the temperatur
e is consider
ed always satisfied.
The scheme is indicative and wants to demonstrate only the components that can be managed by the boiler/thermostove. Any r
elay pumps
must be contr
olled separately fr
om the boiler/thermostove.
