CONTROL OF ANY 3-WAY VALVE FOR THE DOMESTIC HOT WATER CIRCUIT
The Diva Plus thermo stove is equipped with a control as per standard for any motorised 3-way valve to be installed on the domestic hot water circuit. A
cable with 4 wires escapes from the rear part of the thermo stove, which can be used to control this valve. The four wires in the cable have different colours,
precisely:
1. Blue wire = COMMON TO 3-WAY VALVE
2. Black wire = PELLET THERMO STOVE SIDE
3. Brown wire = GAS BOILER SIDE
4. Yellow/green wire = EARTH
Below find a connection example using a 3-way valve with spring return. Remember that the hydraulic connection must be made in a way that when the
valve is at rest, the water passes from the gas boiler. Only when the pellet thermo stove temperature is sufficient (value set from control panel), the 3-way
valve is powered and therefore closes the gas boiler circuit and opens the Diva Plus thermo stove circuit.
N.B.: the brown wire can be used to control any service relay.
