4.5 FUNCTIONS OF THE UNIT
Basically, the electronic unit checks the
working of the heating system; in addition,
it has also other auxiliary and safety func-
tions.
Main function - The unit reads the water
temperature of the boiler, when it exceeds
the set temperature, the unit starts the cir-
culation pump of the heating system. When
the temperature goes under the set value,
the pump stops, allowing the temperature
to go up again.
Secondary functions - When the tempera-
ture exceeds the set values (A02, A03, A05),
the correspondent clamps activate (Valve,

use of the thermal cooker.
Sanitary function - When the sanitary hot
water function is required, the presence of
the liquid flow is detected, so the heating
system pump stops and gives prevalence to
the sanitary hot water. The pump restarts it
