Have HVAC Questions? Ask an HVAC Expert for Answers
Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond sometimes I get your replies late so there may be a delay in my response.
Did you go into the setup mode on the thermostat and make sure you selected the system you have?
If you do not have a heat pump you said you have a wire connected to the B terminal?
Connect the B wire to the W terminal and try it. It should heat.
We are on the honor system for our time, all I ask is please rate my service using the STAR RATING LINK on your page before you leave. If you are not happy with the service please let me know before leaving a negative rating. This is the only way I am paid or credited through the site for my time. This will also allow you to get directly back to me for FREE follow up questions and tips are greatly appreciated! Thanks
sorry for the delay in someone getting back to you.
Is the thermostat still functioning as it should?
The B terminal is an accessory terminal to Win heat mode. So both will work. Moving the B wire to W simply calls for heat from another terminal.
On your system just leave
red to r
yellow to y
green to g
and the B to w
If you need to rate service you will find it at the top of the page with a 5 level rating system.
