Note that the plumbing connection must be done in such a way that when the valve is at rest, the domestic water passes
from the coupled gas. Only when the wood-burning appliance temperature is sufficiently high (value set via control unit
on valve thermostat) is the three-way valve powered, closing the water circuit in the coupled boiler and opening the
water circuit in the wood-burning appliance.
Below is an example of connection to the three-way: motorised valve:
Example of electrical connection
- LINE: Connect terminals 1 and 2 to the electrical power supply (terminals already connected to power supply cable
in the factory).
- AUX: This is used to control a boiler coupled with the heating system where present. Connect terminals 4 and 5 (or 3
and 4 depending on the type of connection to the coupled boiler) to the RT. (Room Thermostat) contact on the boiler.
