Push the Relay
button.
The Relay will light up white
and switch on the boiler.
Push the Relay
button again.
The Relay light will turn off
to indicate the boiler is off.
Note: If the boiler doesn’t switch on when the white light is on, the Relay can be incorrectly wired to the boiler. In
this case, check where the grey and black wires are connected. Please note that some boilers can take up to 20
minutes to respond after pushing the Relay’s button.
In doubt, please read in your boiler’s instructions manual [ the «room thermostat» section].
