Harmoni 100+Thermostat
The Harmoni 100+is a Wi-Fi enabled digital thermostat
designed to improve the thermal comfort of your home by
providing programming of your underfloor heating system. It

1. Air sensor located inside the thermostat.
2. Sensor installed on the floor (check underfloor
heating instructions for more details).
This thermostat is not a safety device and should only
be used for its purpose. To avoid damaging the floor, you
must select the correct floor type during the thermostat
programming process.

box that has a depth of at least 35mm
