    Honeywell T3R thermostat keeps increasing the temp.

    Hi, over the last couple of days we’ve come home and found our house at 26 to 27 degrees. But our thermostats are set to factory settings which whilst during the day should be 16 degrees. I’ve looked through the settings and nothings changed and have no idea why the house is randomly heating...

    Honeywell T3R anyone know how to change language?

    Had a look but can’t fathom out to change language, mine is in German for some reason. there is nothing on Honeywell website. if I do factory reset, will it need re-pairing to base unit? Tia
