Where do thermostat wires connect to outdoor a/c unit nordyne s3qa series

I cant see your cable or terminals, I don't know who made the A/C or thermostat - so it's hard to know for sure.

You could look at the other end to see which terminals the red and white wires are connected and connect them to the same terminals at the other end.

Otherwise, they are wired to follow a color code. Red wire to the "R" terminal and White wire to the "W" terminal.

Good luck!

Hi, I have a baxi solo boiler WM60/4RS and a Landis & Gyr RWB252 timer but my Honeywell T6160 thermostat has nether been connected, can anybody shed light on the wiring connections please.

The color code for thermostat wiring is as follows.
The "R" terminal is power into the stat from the boiler control transformer. Normally 24 volts. The "Y" terminal is for cooling. Normally left blank for a boiler. The "W" terminal is for heat. This one used to start the heating cycle.The "G" terminal is for fan operation. Probably not used for a boiler. Check the boiler terminal board for these functions and write down the wire color on each one. Match the boiler colors to the right function on the stat. If you need more than this, let me know.

Brother took off wall sensor wiring and now I don't know what colored wires go together

The solid white wire from each sensor goes to terminal #2 and the white wires with the black tracers go to terminal #3.

I have a Lux DMH110 therostat, I have four wires; red, white blue and green I don't know there to put the blue wire. On the direction it has Y for a/c compressor I don;t have a yellow wire. Where do...

The color of the wires is a guide only. The lettered terminals on the thermostat are important To pay attention to. R- is 24 volt power w- is heat g- is for the fan y- is for your ac. Sometimes The wire colors matchup sometimes they don't. Your blue wire should go to the y terminal If you have ac.

Wiring thermostat to a American Standard 5ton air handler I don't have the schematics Model twe6a300ab serial# e23176168 year 6-1990

On the thermosta there are terminals, what you need to do is look at the old thermostat that you are replacing and make a note to yourself; what color of wire goes to which terminals,, Rc, R, C, G, W, Y, O, ect.
This is because the installer can use any color of wire. Then just hook the wires up to the same lettered terminals. American Standard should be standard terminal setup.

I need to know how to rewire my heil air conditioner 6 wires are lose?? they are red white orange black red and purple!!!! Model number ph5036akb4

the wires at the thermostat????...this can be very tricky because the colors could mean nothing...every installer can wire it differently...if they used one continuous thermostat wire it's not too have to go down to your furnace and look in the fan compartment or wherever the thermostat wires enter the furnasce....generally a brown wire with 5 wires colored inside....find the wires where they connect to the furnace circuit board , terminal strip or fan centre and write down all wires and their corresponding terminals...for example...Red wire is on "R"white wire is on "W" and they may not match their color....thats ok.....then connect them at the thermostat accordingly////if you only have 4 wires you will require the jumper wire between RH & RC ...if you have 5 wires...remove the jumper or ignore that....good luck :)

I think someone has used wiring that didn't come with the opener. One the rear of the motor unit are wiring terminals. The sensors connect to terminals 2 and 3. Whichever color wire is connected to terminal 2 goes to the screw marked white and the wire on terminal 3 goes to the screw marked black. This information is if you have a Craftsman or Chamberlain opener.

Replacing a thermostat

Typically if you are replacing a heat only thermostat you will have two or three wires. On the old thermostat these wires will be attached to terminals marked "R", "W" and maybe "G". Document what color wires goes to which terminal and transpose these to the new thermostat. If you have a heat and cool thermostat, you will have two or three more wires and connected to terminals labeled "C", "B" and "Y". Again, transpose these wires to the new thermostat as best you can.
