I have a noma programmable thermostat 52-2558-8 & Lennox furnacec33-25b-2-3
I am running the fan on "on" which means it should not turn off - but it does turn off and then start again after a few minutes - I disabled the cycling and it still turns off and restarts - I call a lenox tech and he said the noma thermostat is not compable to my lennox furnace - is this true should I buy another make of thermostat ?- or is there something else I should try?
