ExAMPLE OF APPLICATION
Boiler - Fireplace stove

IMPORTANT
In presence of water with hardness above 25 ÷ 30 ° Fr, is prescribed an
appropriate treatment of the heating water, in order to avoid limescale
problems. It should
be noted that even a small quantity of limescale, could reduce the per-
formances of the domestic side.
The materials of construction are in compliance with the Directive 98/83
EC.
Despite the fittings are mounted at the factory, it is advisable to monitor
all screw connections. Equally important is to do a pressure test during
the operation.
Exceeding above listed limits may cause damages to module and impair
warranty terms consequently

Controller
PRIMARY RETURN 3-PORT PROPORTIONAL MIxING VALVE (ONLY WITH DHW PRODUCTION KIT)
Function: the mixing valve is thermostatically controlled through a bulb connected on the DHW
outlet pipe. In function of the demand of DHW, the valve will increase/decrease the opening.
The temperature is adjustable from 40 to 70°C. The expansion of the liquid inside the bulb deter-
mine the functioning of the valve. Connection M30x1,5
3-port valve with body in brass – No. 3 threaded male connections G1" with flat seat. Stroke of
the shutter 3,7 mm.
With the valve's stem in lower position the port A is closed, with the valve's stem in high position
the port B is closed.
