to start off i have very little HVAC knowledge. I am replacing my Honeywell t87f thermostat with a ritetemp 6022 programmable thermostat. I have followed all direction and wired it up however, i am now experiencing some problems. (i.e. the fan blows cold air for a while and never kicks the heat on) all of the wires matched colors except for my blue wire, i have no idea where it should be goin. Please let me know if you can help. Thanks!!

you need the other side of the transformer C coming up to the subbase of the new stat you have to have a true 24v on (R to C).the old stat worked on a feedback and there was no solid state that required 24V so it all worked on feedbacks thru Y,G,W with the T87....if you don't have a spare wire for C from the subbase to the furnace use the Y (might be YELLOW)cooling wire for now( SHUT OF POWER ON THE FURNACE).flip it to C on the base and remove it off Y in the furnace and wire it ti the C side of the 24V on the exsisting TR
It ain't going to get any lighter looking at it!
