A/C Turns on when I turn on the heater
When I turn on my heater the A/C also turn on. Is a gas furnace. So I have to turn the A/C beaker down. If I only use the A/C it work fine. Any ideas. I think my digital thermostat is damaged...

Correct, but when in FAN mode, you have the option of HI/LO/AUTO. Pick AUTO. Doug
