Something's wrong two zone one up one in den,gas heat when thermostat upstairs is on heat down comes on too, I think its wired wrong! When you turn up downstairs heat you don't hear that little click in thermostat and heat don't come up, I need help the guy who installed it won't come back he wants to charge her for not doing his job right he blames electric guy unreal I'm sure its easy fix just need some you guys to trouble shoot it for me thanks JOEY
