Customer Question

The Honeywell thermostat that I bought is Model Number RTH9580WF. I have a problem were the system is providing nothing but hot air. My old thermostat had six wires and think I connected them wrong. I have a control, white, yellow, green, red and orange. The only wire that I didn't know how to install because there was no instruction was the orange wire. I connected it to W2-Aux/E. Need your help ASAP. My house temp is 85 and it is 80 outside.

Hello and thanks for using this service, if you have been waiting do not worry or get upset. I am HVAC Guru an extremely experienced tech on the site and I try to get to as many customers as I can. I just picked up your question now. NOTE it takes time for me to type research and add links so please wait for me to respond back I can only do this so fast. Secondly I am not paid anything until you rate my service good using the STAR RATING LINK at the top of your page, the money is paid to the site not me directly. Answer: The orange wire goes to the O/B terminal and you have to also go into the installer menu and set the system you have which sounds like just a single stage heat pump unit. Then it should work. All I ask is please use the Star Rating Link at the top of your page before leaving, that is the only way I am paid anything through the are greatly appreciated so thank you very much for using this service. If you have any other questions just post back to me here anytime!
