Electric control unit
The electric control unit (supplied with the fireplace heating
system on request) is used to control and command the start-up
of the pump and any motorised 3-way valves.
It is composed of:
master switch
(used to supply power to the control unit
itself);
pump adjustable thermostat
(used to activate or
deactivate the pump on reaching, or not, the temperature
we set on the thermostat itself);
valve adjustable thermostat
(used to exchange any
motorised valve on reaching, or not, the temperature we set
on the thermostat itself. It is normally used for the DHW
connection with coupling to another boiler);
aux thermostat
(used to control any service associated
boiler);
service thermostat
(used to activate or deactivate the
circulation pump on reaching, or not, the temperature we
set on the thermostat itself);
thermometer
(indicates the temperature of the water inside
the fireplace heating system);
acoustic alarm
(it activates whenever the water of the
body-boiler reaches and exceeds the temperature of 90-
95°C);
For the connection to the control unit, consult the layout
inside the box of the same.
The control unit has an internal fuse
T 3,15A.
