TECHNICAL DATA
DIFFERENTIAL AIR PRESSURE SWITCH FOR FAN CONTROL
To guarantee maximum safety in flue exhaust, a differential pressure switch
is installed on room-sealed boilers and on forced draught boilers. This
pressure switch automatically controls perfect functioning of the fan and the
passage of both external air and exhaust flue pipes.
DIVERTER VALVE VC 6012MG6000
The diverter valve is the device which controls the boiler switching from
central heating to d.h. water circuit and vice versa. The diverter valve is fitted
with a manual command lever C (fig. 2) which, when set on the top position,
towards the valve head, allows the boiler operating on the domestic hot water
circuit while, when set on the low position, the boiler operates on the central
heating circuit.
When the C lever is set on the central position, it allows the actuator on
midway.
In this position,
to be used only in case of motor failure or damage
, both
central heating and domestic hot water ports are open and both domestic hot
water and central heating circuits are operating.
To restore the initial position, separate the actuator and the valve body
following instructions from no.1 to no.4 (see fig.1).
To separate the motor from the valve body proceed as follows (fig.1):
1.
Press button A under the motor.
2.
Simultaneously keep the A button pressed and turn the actuator counter-
clockwise;
3.
Lift off the motor
4.
To disconnect the power supply cable press the B tap located on the pin
C.
See fig. 3 to perform the electrical wiring of the diverter valve to the main printed circuit board.
DOMESTIC HOT WATER PRODUCTION
The boilers are designed and built for the production of domestic hot water with a 25 lt. capacity storage tank. One advantage of
this system is the amount of water immediately available, thanks to the large exchanger surface of the coil inside the boiler which
allows different services to be used simultaneously.
As well as the use of a porcelain treated glass coating on both the coil and the internal boiler surface to guarantee high levels of
hygiene, the inside of the boiler also has a magnesium anode which, in the event of galvanic currents, preserves it from corrosion
to ensure it a longer working life.
