1 Heat/1 Cool Thermostat
What you will need to have:
- Phillips screwdriver (I would recommend a six-in-1)
- A Precision screwdriver (phillips or flat)
- W ire Strippers
- A Level (preferably a torpedo level)
- PPE (Private Protection Gear, security glasses, gloves, and so on…)
In this tutorial we are assuming that the thermostat wire has been ran from your furnace to your thermostat place.
Initial step is to place on your PPE gear followed by turning off the breaker to your furnace. If you have a switch by your furnace I would also recommend turning that to the off position as properly.Failing to do this step can, and most most likely will, outcome in broken gear. BE Positive TO TURN THE Program OFF!
Go to exactly where your existing thermostat is installed or to the place exactly where you are going to be installing a new thermostat. If this is a new set up and you are pulling wire to the place I would recommend pulling 18/eight thermostat wire. Most thermostats and typical (single heat / single cool) systems will not call for much more than five wire to run your fan, heating, and cooling capabilities. Nevertheless, it is by no means a terrible thought to have extra wire for future expansion of your method (I.E. outside air sensor, humidification, and so on…) or in-case a wire gets shorted out for the duration of the wire pull.
Take away your existing thermostat from its place. If your thermostat has mercury bulbs it is essential that you do not just throw it away in your garbage. Mercury is toxic and should really be handled as such. If you have a single of these thermostats please go to the following web-site for suitable disposal and handling of your old t-stat. (epa.gov)
As soon as your thermostat is removed, identify what sort of wire was pulled. Based on how old your property is you could have anyplace amongst two (two) to eight (eight) wire pulled. Most of today’s digital thermostats call for at least 5 wire to be pulled to the thermostat place. If you only have two wire pulled to your thermostat place do not be concerned you wont necessarily need to have to pull much more wire. There are wireless thermostats out there on the marketplace.
Hopefully you have at least 5 (five) wire pulled to the place. We’re going to base the rest of the tutorial with the believed that you have at least 5 wire pulled.
You should really have the following wire colors:
Red / White / Yellow / Green / Blue
On some older wires your colors could not be specifically the very same but these colors are the typical presently, at least right here in the USA.
For a much better understanding of your method, and what each and every wire is for, I will break them down.
Red (R terminal): Your red wire is your handle voltage wire. It is the wire that delivers a 24v signal from your Furnace to your Thermostat which enables your thermostat to pass signals back to your furnace to Heat, Cool, run your Fan, and any accessories that you could have. It also supplies energy to your digital thermostat and enables your thermostat to show all of it is capabilities. Temperature, time, date, and so on…
White (W or W1 terminal): The white wire is in your handle circuit for heating. It enables a signal to travel from your thermostat to your furnace to inform it when to turn the heat on.
Yellow (Y or Y1 terminal): The yellow wire is in your handle circuit for cooling. It enables a signal to travel from your thermostat to your furnace when it is time to cool.
Green (G terminal): The green wire is in your handle circuit for your Fan. It enables a signal to travel from your thermostat to your furnace to run the fan.
Blue (C or X or B terminal): The blue wire is your prevalent wire. It completes the handle voltage circuit for your thermostat and enables your thermostat to have a show and back-lights.
Now that you have a much better understanding of what each and every wire is truly for let’s get started installing your thermostat.
Separate your thermostats face plate from it is base-plate. Spot your face-plate in a protected spot. Thread the wire by means of the back of the base-plate and use the mounting hardware (commonly supplied with the thermostat) to mount your thermostat. Make positive that your thermostat base-plate is level with your torpedo level. As soon as you have mounted your base-plate we can commence wiring your thermostat.
Initial factor is very first If the sheathing of the thermostat wire is nonetheless in-tact we need to have to strip back sufficient sheathing so we can perform with our 5 wires. If you have sufficient slack on your thermostat wire I recommend stripping off at least six inches of sheathing leaving the 5 wires exposed and no longer bound by the sheathing.
Typical 18/five Wire.
If you do not have sufficient slack to do this just use what you have from the earlier thermostat
As soon as the wires are exposed we will strip about 1/four” from each and every of the person wires. Exposing the copper.
There is no precise order you have to do the following but for the purposes of this tutorial I am going to assign an order to connect your wires to the base plate.
We’ll get started with the Red wire. Plug the exposed copper from the RED wire into the R terminal. Use your handle screwdriver to screw the terminal screw down onto the wire. Give a light tug, on the now attached wire, to assure that the wire is secured to the base-plate.
Subsequent we will attach the Blue wire. Insert the exposed copper into the C terminal of your base-plate. This terminal could also be labeled with an X or a B. If you have all of these labels in your base-plate just set up the wire into the C terminal. Use your handle screwdriver to screw the terminal screw down onto the wire. Give a light tug, on the now attached wire, to assure that the wire is secured to the base-plate.
Then we will take the Green wire. Insert the exposed copper wire into the G terminal of the thermostats base-plate. Use your handle screwdriver to screw the terminal screw down onto the wire. Give a light tug, on the now attached wire, to assure that the wire is secured to the base-plate.
Subsequent we’ll take the White wire. Plug the exposed copper from the WHITE wire into the W terminal on your base-plate. This terminal could also be labeled W1 or W1/O based on your thermostat. Use your handle screwdriver to screw the terminal screw down onto the wire. Give a light tug, on the now attached wire, to assure that the wire is secured to the base-plate.
Lastly we’ll take the Yellow wire and plug the exposed copper into the Y terminal. This terminal could also be labeled Y1. Use your handle screwdriver to screw the terminal screw down onto the wire. Give a light tug, on the now attached wire, to assure that the wire is secured to the base-plate.
Congratulations, you have wired your thermostat! Now, snap your faceplate back onto your base-plate. Viola! You are carried out with that portion of the installation.
Now, just to assure we are matching on the furnace finish you will need to have to find your furnace and take away the access panels to verify that the wiring matches up. Whilst the colour coordination that I’ve shown you right here is essentially a typical now, you by no means know what the original technician did. So, it is finest to double verify his wiring to assure that it matches with what we’ve just carried out with the thermostat. Double verify to make positive that each and every wire matches specifically the very same as we just did:
- Red to R
- Blue to C
- Green to G
- White to W
- Yellow to Y
Be positive to transform any discrepancies you could uncover in the furnace wiring. As soon as you are carried out with this, place the panels back onto your furnace. Go to your breaker and energy on the furnace once again. If you had a service disconnect (a switch) subsequent to your furnace go and turn this on at this time as properly.
Now the enjoyable portion. Go back to your thermostat and verify to see if it is show is on. To assure every thing is functioning correctly run it by means of each and every function: Fan on, Heat on, A/C on.
If each and every mode runs appropriately congratulations, you have carried out every thing appropriately! You have effectively installed your thermostat. I hope you have located this tutorial valuable.
