Asked Nov 6, 2010, 09:39 PM
Hey I got a new thermostat for the house but went to replace the old one and I have a Yellow, Green, Red, White, and Blue wires but the thermostat has the Y, G, Rh, Rc, and W. An electrician friend hooked it up for me and did the following:
Y - Yellow
G - Green
Rh - Red with a jumper to Rc
W - White
And left the blue off
Everything works OK except my heat... it only runs when the fan is set to "On" and not at all when set to "Auto"
