Make sure you have a heat pump thermostat. Standard stat wire and stat wiring are as follows.

  • R to red
  • W to white
  • Y to yellow
  • G to green
  • O/B to orange
  • C to blue or W2 to blue
Your wire colors and stat brand and model number would be more helpful if this does not clarify. Repost with additional information and I would be glad to help further.

HI, I have a White Rodgers model 1F89-211 thermostat. All I did was move it to the opposite side of a wall into another room and now it runs backwards. I heats on cool and cools on heat. Help?


Phillip...

The SECRET is to connect it exactly as it was (before).

The screws on the control are color coded

R,W, Y AND Green... TYPICALLY that MATCHES THE TERMINALS OF THE SAME COLOR inside you heater controller.

Yes ... Red, White... Yellow...

What you need to do is look at the picture you took... or the notes you took BEFORE disconnecting those wires...

ELSE...

Go to where the HEATER CONTROL BOARD IS...

Pull the front cover... Snap a picture for your memoirs...

and write a TRUTH TABLE

AT THE HEATER... TAKE NOTES...!!

RED SCREW = (for example red wire)
Yellow =
Green =
White =

BACK AT THE Thermostat Screws:

RED = (
SAME COLOR WIRE as at the HEATER)
Yellow = (SAME COLOR
WIRE AS THE HEATER)
Green = (
SAME COLOR WIRE AS THE HEATER)
White = (
SAME COLOR WIRE AS THE HEATER)

You should be fine...

What wires coming from the theromstat conect to which wires coming out of the wall


suggest this: hire a technician to fix it for you. you would need the wiring diagram for the thermostat and to find which wires go where in the wall.

this is a task that is normally beyond the ability of an owner. It requires some technical knowledge of thermostat wiring, as well as using a voltmeter.

you might post an ad to locate another owner of your model RV, then ask them to pull the thermostat off the wall and take some pictures to send to you - showing the wiring connected.

Pay attention to wires from control box itself at the ceiling assy. Sometimes they will use a different color from control box, to thermostat. For example: Green coming out of control box, is attached to a blue running to thermostat, so you would attach that blue, to "G" (fan) on thermostat. Match thermostat colors to what is at the control box originally, not what color they used to run it to thermostat from there. Most try to match them, but others don't. What model Ac unit, and what model of thermostat do you have?

Paul, you will need to look at the indoor unit and determine which wires from outside are connected inside. let me know. more then likley they color coded it but better to be safe. also does the fan inside still run if you switch thermostat to fan ON. if not the transformer may have blown, if yes you need to make sure you shut the breaker controlling the inoor unit off while your messing with the wires, or you will blow the transformer in the furnace

Wiring on a RCA RJ-45 wall jack


the RJ45 wallplate is not meant for ethernet. It's an 8P8C connector for a phone. Will it work as a network jack? Maybe. I wouldn't use it, but if you really want to try, wire it thusly:

1 Blue --- Orange/White
2 Orange --- Orange
3 Black --- Green/White
4 Red --- Blue
5 Green --- Blue/White
6 Yellow --- Green
7 Brown --- Brown/White
8 White --- Brown

I'd still recommend a CAT5 wallplate with a CAT5 jack.

Where to hook up wires?


First, take the old thermostat off the wall.

there should be different colored wires coming out of the wall still connected to the old thermo.

on the new thermo, there might be a wire color chart in the instructions or on the inside of the new thermo.

You should be able to line up the colors and install them that way. let me know if you have any other problems
