I have an old maple chase thermostat, not sure of the model #, but everything is manual. No batteries included... The AC does not turn on neither does the heat. Turned the circuit breakers on and off nothing happened, thermostat seams to work, it says its 80 degrees in here, and it sure does feel like it. Any help would be appreciated!

Thanks in advance

You could have a bad transformer or 3 amp fuse in the system... might want to change the tstat out to a digital one too.
