The "Heating off" mode, cuts off the control of your heating by the thermostat by applying a set point of 4°.
When this mode is activated, your thermostat no longer responds to the orders given, whether from the website, the application or from the physical thermostat.
If you have a Multizone pilot wire, an Off-Frost order will be sent to the secondary zones.
To reactivate the control of your heating, from your "Dashboard", go to "Settings" where you will find the details of your temperatures.
Sliding the button "Heating control": simply click on the button, active heating = green background / inactive heating = grey background.
