Night-time temperature reduction
Overnight, or if you are out, it is best to set the thermostat to
a lower temperature, as it will save you energy. In general a
reduction of 5°C is recommended, but this will depend on your
heating system and the amount of insulation in your home.

touch zone for about 10 seconds
to activate the binding screen.

to confirm the Gateway and the
thermostat are now connected.
