Hi,

I have a NOMA Programmable 7-Day Thermostat, but today it seems to have gone strange. I had it on the Cool and heat started coming out of the vents. I thought the air conditioning was broken, so I turned the thermostat off, but a little while later the vent came on with hot air again? How is that possible if the thermostat is off. I have tried resetting the thermostat by pressing reset and taking out the batteries, but it is not resetting? What should I do before calling a repair man for $99 dollars an hour?

Help me please

The problem may not be with the actual stat, but with a short in the thermostat wiring, or in the control board at the air handler.

Any troublingshooting beyond what you have done already will require taking apart the wiring to the stat to begin looking for the problem.

Heat is not coming from NOMA Programmable 7-Day Thermostat... can you please help me... even thoug on monitor it does say heat is on...
