SOURCE: Installing Honeywell RTH7000 - I have too many wires!

check to see if the B terminal is on the new t-stat if connect to it , but this terminal refers to heat pumps and is normally use to energize the reversing valve on the outside unit and not used on ac units , but normally the tag O/B is the same terminal on therostats

Ct87n thermstat is hooked up and the heater is on because i smell the heat but it is not blowing out the vent


The blower motor isn't running. At the thermostat, red wire to the R terminal white wire to W terminal.or W2 If the blower still doesn't run It's probably not the thermostat.

We had a Honeywell CT87N round thermostat installed. The heat comes on but the actual temp on the bottom stays much lower - like 8 degrees lower. Is there a way to calibrate the thermostat so that they...


One thing you can try is to remove cover, it just snaps in place.There are two plastic leveling posts at top two sides. You will need a small level commonly called a torpedo level to set on these leveling points.It should be very close to level,bubble in middle. If it's not look at base plate against wall and locate two lower mounting screws there will be a small slot where the screws go into wall to allow for slight adjustment.You will need a small screwdriver to back these two screws out a little maybe 1 turn.Adjust thermostat base so that level has bubble in middle and carefully tighten the screws,keeping t-stat held level. This should help some but it is not unusual for set temp. ont-stat to be off 3-5 degrees from thermometer reading. Hope this helps you.Thanks.

I need to move a thermostat but I can't get the thermostat separated from the wall mount. Is there a trick to this? Thermostat is a honeywell ct87n/k.


I can help you out on this , there should be about 3 flat head screws that are difficult to see under the round cover/front cover , there should be 3 peices to the entire t-stat , the front comes off easy and then there are the 3 screws and then the base mounted to the wall. let me know how this works.
