I have a gas heater on my central air and heat unit.I changed my thermostat to a honeywell RTH110B non-programmable. My system has 4 wires(red,green,white,and yellow).I hooked the wires up according to the colors and letters.My central air and heat unit is a Ruud it has a honeywell control by the furnace.My compressor will not work now, at first the fan would not come on before and after I changed my thermostat.My fan just started working and the compressor stopped.I need help.

I'd really like to know what the Honeywell contol is? A zone control board?
