There are three parts to a T87F thermostat. Outer ring, thermostat body, and base mount. Remove the snap on ring that goes around the dial. Remove three screws from the thermostat that mount it to its base. Remove the thermostat. Disconnect and record what screws each wire attaches to. Remove the screws holding the base to the wall.

Can I use a household thermostat in an RV for heat and air?


As long as it is a 24 volt A/C system, which most are (look at the old thermostat in your RV) , and as long as it is a digital thermostat. Do NOT use one with mercury in it like the old round brown Honeywell that everybody has. The non-digital thermostats that use "snap-action" springs can be used, but they are mostly junk. Spend $35 on a decent digital and you will be fine.

Outdoor AC unit runs for about 2 minutes after air handler shuts off


Hello, it is possible that the new thermostat has some type of time delay built in it. But typically this would shut of the outdoor unit first and then the air handler.

I have an old honeywell thermostat, non digital it is about 4 degrees off. is there a way to adjust it. I set it at 74 and it does not shut off until it reached 78 thanks


If your thermostat has a mercury bulb it has to be level to be accurate. Check and make sure it is level. If the thermostat is level as a heating tech. i would next check the amp. draw through the thermostat so I could make sure the heat anticipator is set properly. This may be more than a home owner wants to tackle.

Manual Thermostat replcaement with Programmable Digital unit.


Hopefully there are markings on the old t-stat as to what terminal is what.
on the honeywell 8000 use the heat pump labeling and then the standard wiring would be
R- red
AUX-white
Y- yellow
B- O/B
C- black
G- green
There should not be a bare wire, it probably just has the insulation stripped back way too far.
You should probably open the furnace and compare the terminal label in the furnace to the wire color. normally yellow and blue pass through the furnace and are wire nutted to wires going to the outdoor unit. In the furnace the white wire will connect to the w or w1 terminal. also, you will need to set the Honeywell stat to have the following parameters.
170-7
190-1
200-0
other parameters that I did not specify, you may read the manual and make your own decision but I recommend factory settings for the other parameters
