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...

It's probably the AC fan only, not the compressor. I had the same issue. It was the setting for the fan. It was a little confusing if I recall. But you need to change it to Auto. IMO it is poor logic by the thermostat designer.
