Thermostat frequently asked questions Can I use a wall-mount thermostat to control my heater if it already has a built-in thermostat? A built-in control is convenient to install when the walls are already finished. However, a wall thermostat controls the room temperature more accurately, is more convenient to use, and offers a broader selection of models. Electronic thermostats provide more accuracy and can help you save money on your electric bill. Where should I install my wall-mount thermostat? Always mount a thermostat on an inside wall away from drafts, direct sunlight, or any appliances that could affect its temperature reading. Mount wall thermostats used with a baseboard heater across the room from the heater. If you have two or more heaters in a large room, place the thermostat in a central location. Can I control all the heaters in my house with one thermostat?
How to Wire a Thermostat | HVAC Control
The systems use a common code, First thing you need to do is go to Google or similar and punch in furance thermostat wiring or similar and study for minites so the terms used makes sence. It is not compilcated to install nor operate and it is not expensive. I have installed 4 now including my own and “fixed” 2 others that were installed wrong and all work perfectly.
Here is how I do it.
How to Hook Up a Home Thermostat – Location of New Thermostat Installation Now that you have selected the proper thermostat you want to install the new thermostat in place of the old thermostat. It is best to place the thermostat in the same location as the old thermostat.
Always follow manufacturers instructions for both the thermostat and the HVAC system. Additional articles on this site concerning thermostats and wiring can help you solve your problem or correctly wire a new thermostat. These charts and diagrams only represent the basic system. It is possible your system is equipped with additional HVAC components such as a humidifier or electronic air cleaner.
Depending on the manufacturer and the designer of the components will depend on how the additional components are wired or integrated into your system or thermostat. It corresponds with the chart below to explain the thermostat terminal functions. Before uninstalling the old thermostat take a picture of the wiring with your cell phone before removing the wires. This way you have a reference. At the minimum draw a picture of it referencing the wires, wire color and what terminal the wire is attached to what terminal.
The photo and the drawing reference can be used later to make sure you wire the new thermostat properly. Make sure you do not make this same mistake others make.

The first thermostat built to listen and learn from your voice – interact with your thermostat using simple voice commands. Advanced ‘far-field’ voice-control technology that breaks through the ambient noise of a busy household and recognizes voice commands. Change the temperature of your home by just speaking commands to the thermostat.
Step Three: Set Up the Nest Thermostat. as well as the fan. Push to continue. You’ll then select the fuel source for your heating. If you don’t know this, select “I Don’t Know” from the list. To connect your Nest Thermostat to the app on your phone, you’ll need to enter in an entry key.
You might need a small flat head screwdriver, depending on how your old thermostat is connected. This might also be the perfect time for me to inform you that by doing this project yourself, you assume all risks associated with it. Different wires from the thermostat control the different functions heat, cool, fan of your HVAC. The most common wires are: This switches on the gas, oil, or electric heat. That makes things easy, but that might not be the case with your thermostat. Double check to make sure everything is labelled correctly before disconnecting any wires.
The wires coming out of the wall should look something like this: Do you have four thermostat wires or five? Notice in the above picture that I have five wires available: Notice that this example has six wires connected: If yours looks like this, label them and skip to Step 5. The most common example of this would be if you only had R, G, Y, and W wires at your thermostat.

The fan thermostat controls the fan, turning it on when needed and off when not. These thermostats are available from most electric fan suppliers, as well as Summit Racing. Searching the Summit online catalogue for “thermostat” or “fan switch” will quickly turn up several.
Wiring An Electric Fan with Two Relays After having my new Walker radiator installed with a inch electric fan, I was very dissatisfied with the wiring situation. After reading about it all at MadElectrical. I ordered two relay kits, along with a bunch of other stuff, and rewired my fan. I looked at the wiring the mechanic had originally done when he installed my new radiator and there were six things I didn’t like: Anyway, after mounting two terminal blocks on my firewall, creating a full If this is your first time installing relays, the kit above is the way to go I just phone my orders in: First I disconnected my battery and mounted the two relays on the driver side in my engine compartment.
Then I measured the red wires from 30 on both relays to the terminal block so I could solder them to the fusible link and make a connection to the full power there. Finally, I set up a nice ground for the Ground wire on the electric fan:
How to Install a Six Wire Thermostat
I clearly understood it, but it may have confused you. The control circuits for furnaces and other things commonly use 24 volt circuits, the voltage coming from a transformer wired into the furnace. One wire, often red goes from the transformer to the thermostat. Another wire, often white, goes back to a solenoid operated valve that controls the gas. It also operates a relay to start the fan.
However, not directly, but through limit switches or timers to start the fan a little after the gas comes on and keep it going a little after the gas shuts off.
The two transformers provide the power the thermostat uses to switch on the various relays in turn switch on the power to the fan and the air conditioner or furnace. Let’s see how this power flows through the thermostat when the air conditioner is running.
If you are having problems with a digital thermostat, there are a few simple tests that can be performed to isolate the problem and help you decide whether to replace the thermostat to fix it. Step 1 – Check Temperatures Before getting too involved in testing, check the room temperature on a digital thermometer. If the temperature matches what is being shown on the thermostat, you can verify that the room temp sensor for the thermostat is working.
Any discrepancy here indicates a bad thermostat sensor. While the sensor can probably be replaced, it is more cost and time effective to simply replace the entire unit. The next step will be to check the set point calibration. Step 2 – Calibrate the Room Temp Digital thermostats can be calibrated, meaning that both the set point and room sensors are brought into balance.
Help!! adding 2nd thermostat to control furnace fan
If the unit requires only two wires, the system is only able to heat the space. If any cooling, like an air conditioner, or fan control is required, more wires are needed. Most homeowners with moderate home improvement skills can wire a heat-only thermostat. However, basic safety procedures must be followed whenever working with electricity. If you have any confusion or questions about the process, you should invoke the help of a professional. Additionally, prior to getting started on any work that involves electricity, tell those around you what you’ll be doing.
But thermostats can also be used for home air circulation and filtration with the fan-only setting, helping to save on your energy bills. Wiring the fan-only option is not difficult as long as the thermostat model includes this option, and involves a single wire and a little patience.
Work with the power off whenever possible. When a furnace does not work it may be caused by problems with the furnace or the thermostat. Before troubleshooting your thermostat, check to see if all filters are clean and all hoses to and from the units themselves are free of wear. If these are not causing problems, then it is time to look at specific thermostat issues and possible solutions.
Your thermostat could have aging wiring that is faulty or the transformer may require replacing. A thermostat may need cleaning to eliminate erratic operation. Accumulated dust is a common culprit. First, you should have a small paintbrush, a screwdriver, and a voltmeter. The anticipator is a small metal tab positioned in front of an arcing printed scale. Give it a light push in both directions.
