Functioning as heating station (HS)
The station functions in this mode when „winter” season is selected. For the selection of the
type of heating installation (floor or radiators) please contact an authorised service
company.
If a thermoregulator is connected to the electronic board, the stations functions in
thermal mode only when the surrounding temperature is lower than the set temperature in
the thermoregulator.
9.6
Preset functions related to station safety
1. Anti-freezing protection function.
If the temperature in the installation drops below 9°C,
the system turns on the heating at minimum charge until the temperature reaches 30°C.
2. Post-circulation of the hot water and heating pump function.
The post-circulation cycle
starts only if the system is not in
the
BURNING
state
.
Advantages:
a) it prevents the water from becoming stationary at high temperatures inside the heat
switch. In this way, calcareous deposits are reduced significantly
b) it prevents water from boiling inside the heat switch in the post-heat interval.
These advantages have as result the protection of the heat switch.
3. Pump anti-blocking system and three-way valve.
If the station did not go through a burning cycle in the last
24h
, the pump will be started for
12
seconds
to avoid its blocking. In this time the three-way valve is also activated and
deactivated.
4. Post-ventilation
After each station stop, the ventilator still functions for some time to evacuate completely the
burning gases out of the station and also the water vapours they contain. In this way, both the
ventilator control electric circuit and the primary heat switch, which cools down partially, are
protected.
5. “Legionella” bacteria prevention function
This function is active
for the functioning of the station as accumulation boiler WHW.
When hot water is prepared in the boiler, the ANTILEGIONELLA function is actived
automatically. This function implies that once a week, the temperature of the water in the
boiler is kept at the value of 65°C.
