I bought this Noma thermostat and the heat stays on, no matter what. Even if I detach the front plate the heat remains on. When I reinstall the old mercury swtiched thermostat it works fine. I have a 2 wire hydronic heat system. Can anyone tell me why the heat stays on?
Any advise will help. Thanks so much.
