Themo has three operating modes. It is possible to change the operating modes manually on the device or via the mobile app.


Off Mode

In the off mode, the thermostat maintains a “manual” minimum temperature that is adjustable between 5 and 12 degrees from the application (Frost Protection). Off mode does not require an Internet connection to work.

Smart Schedule (SLS)

In Smart Schedule mode, Themo follows the weekly program entered for it and takes advantage of price optimisation. The thermostat must be connected to a Wi-Fi network to follow the intelligent program. If the Themo is set to Smart Schedule mode and has dropped offline from the Wi-Fi network for more than 24 hours, then the thermostat will keep the minimum temperature that is set for “off-mode”. Temporary disconnections (less than 24 hours)  from the Wi-Fi network do not affect the operation of the Smart Schedule.


In manual mode, the Themo works like a standard thermostat, keeping the set temperature constant around the clock. You can adjust the manual mode temperature, either physically from the thermostat or from the application. Manual mode does not require an Internet connection to operate except for remote control.
