Push the relay
button.
The relay will light up blue
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 blue light is on, the relay is incorrectly wired to the
boiler. In this case, check where the grey and black wires are connected. In doubt, please read in
your boiler’s instructions manual [ the «room thermostat» section].
