Thermostat(wiring)
Trying to get information on how to wire Hunter thermostat model#40070A.The house was built in the late 70's I think.There are 4 wires(red,black,white,ground).Inside the thermostat where you stick the wires looks like this[B,RH,RC,W,Y,G],with the jumper wire on the RH and RC terminals.How do I determine which of my house wires goes to the inside of the thermostat?Thanks any info will be helpful.

Check with Hunter at www.hunterfan.com Go to their customer support center and you can check manuals, FAQ's etc.

I just looked at their website. If you go to the technical support area and plug in the model 40070 - forget the "A"- you can get the manual. It's an Adobe PDF file.

The thermostat will switch 24-volt control-power to three 2-wire circuits---- (1) the gas-valve, (2), the fan (blower) relay, and (3), the compressor-motor contactor located inside the out-door condensing-section.
Each one of these 2-wire circuits has one wire connected to the "C" terminal of the 24-volt control-power transformer.The other terminal of the control-power transformer is identified as "R" .The White thermosat wire will connect the other wire of the gas-valve to the "W" thermostat terminal.The Green wire will connect the other wire of the fan-relay to the "G" thermostat terminal. The Black ( read "Yellow" wire) will connect the other wire of the compressor-motor contactor to the "Y" terminal. The Red wire connects to "R" terminal of the control-power transformer to the "RH" (heat) & "RC" (cool) thermostat terminals.
Call for heat--- therm makes "RH"-to "W" --- gas valve "open"
Fan "manual"--- therm makes "RC"-to "G"--- blower runs
Call for cool-- therm makes "RC"-to "G" and "Y"--- blower runs and compressor-motor contactor switches power to compressor-motor.
Good Luck & Enjoy the Experience!!!!!!!
