Question: I tried to replace my now old Siemens Landis & Staefa REV22 thermostat with the FantiniCosmi C57 model but inserting the two wires as indicated in the instructions the thermostat does not work properly. It stays on when the apartment is heated to the maximum temperature while moving the cursor all the way to the right towards the closing symbol.
I don't know how to fix it and I had to put the old thermostat back.
If someone shows me the solution, thank you.
