How to Install a Thermostat for Split Air Conditioning System

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. First thing is your indoor furance thermostat must have a “fan on” feature, if it doesnt you must buy a new thermostat that does have that feature and install it. Again I am not going into the wiring here as it gets too long winded and depends on your furnace controller type. Nice instructions come wih the ‘stats too. You do this prior to adding Thermostat number 2 then once you have your indoor furnace up and going with your new thermostat you are ready to proceed to the easy part, wiring up the 2nd thermostat to control the fan when running the OWB. Find the two wires that are connected when you sellect Fan On. One of them will have control voltage at all times, the other will have it only when you have selected Fan-On.

How to Replace Your Own Furnace

We carry 4 sizes of front loading forced air furnaces. These models can also be designed to burn coal. Our fan feeds oxygen in from the bottom so the coal burns easily. Shaker grates are installed in all models to help get rid of the clinkers. Watch this video first on the outdoor forced air wood furnace:

The heater firebox is constructed of 14 and 16 gauge stainless steel for the best heat transfer possible. The all stainless steel firebox also resists rusting and burnout that occur in standard carbon steel.

The stainless steel smoke stack that passes through the water chamber resisting burnout and corrosion.

Dometic Single Zone Cool/Furnace Control Kit with LCD Thermostat

This leaves me with the following questions Does the currently wired configuration support automatic two-stage operations for Heat? Does the currently wired configuration support automatic two-stage operations for AC? Does the stage delay timer apply to AC or only heating? All the mentions I see only reference heating, so I’m inclined to believe it does not apply to AC.

Types of Thermostat Wire. There are a variety of thermostat wire types. The main difference setting each apart is the number of colored wires. HVAC systems with more functions need more wires to communicate to and from the thermostat.

Video of the Day Instructions Turn off the power to your furnace by turning the switch on the side of the furnace to the “off” position. Remove the access panel on the front of the furnace and locate the control board. You will find a terminal strip where the low voltage control wiring hooks up to. Locate the “G” terminal, which controls the blower operation from the thermostat, on the board. Connect the green low voltage wire to the “G” terminal and put the access panel back on the front of the furnace.

If no green wire exists you may need to pull a new thermostat wire from the furnace to the thermostat.

Gas & Electric Furnace Troubleshooting Simplified

We would love to have your business! Below we have a YouTube video on gas furnace troubleshooting made by hvacrepairguy. I hope this video will help you solve your furnace problems.

Replacing a Thermostat in Your Home 1 Purchase a replacement thermostat that will work with your system. Review the compatibilities listed on the packaging of the replacement thermostat. Most replacement thermostats are compatible with all common systems. However, if your system is unique, finding a replacement thermostat may be difficult.

Here are your basic options information that should be easily found on the packaging: Used when you have separate heating and air conditioning units “Works with 2 stage or multi-stage heating or cooling”: Used for heating or cooling units that have designated high and low speeds “Works with Direct Line Voltage”: Used with or direct current power sources to power the thermostat generally seen in older homes “Works with 24mV”: Used when both heating and cooling are individually controlled in different areas from the same system 2 Review the manufacturer instructions for wiring your replacement thermostat.

Most thermostats utilize similar installation methods; however, it’s beneficial to read all materials and preview all pictures provided for how to install your new thermostat. Or you risk literally being stuck in the cold! Reading instructions is a total drag, yes. But this is not something you want to mess up!

How to Connect a Programmable Thermostat to a Gas Furnace

I noticed a problem right away with trying to maintain a comfortable temperature in the rig. It seemed like there were large swings in temperature between the furnace or the AC on and off cycles. Also with the analog type slider knob it was hard to precisely adjust the temperature. I did a little research on the web and found many people had upgraded to a digital type thermostat and were happy with the results. Most of the articles recommended using the Hunter brand Model B, as it was capable of controlling the cooling and heating, plus the fan function.

Matthew: If this is the case, then hook the outdoor unit wire back up to the furnace; then go outside and unhook the wire from the outdoor unit.

Your furnace thermostat is an essential part of a home furnace system. The thermostat is responsible for regulating the other systems inside the furnace; it is primarily in charge of maintaining the temperature at the which that you set. If the thermostat is not working properly, you may find that your home is colder or warmer than you would like it to be. Your electric bill may also shock you, as the furnace may be overworked. Read on for a brief and comprehensive guide on how to wire a furnace thermostat.

Step 1 – Prepare the Furnace First, turn off the furnace. Most furnaces have a power switch in the central control or the heating system. If the wire is not already connected to the furnace, connect it to the proper terminal according to your furnace owner’s manual. Run the wire through the furnace covering and into the control panel where the thermostat will be located. If there is not an opening in the control panel, you will need to cut one on your own. Step 2 – Install the Thermostat When you have decided where the thermostat will sit, you can install it in the drywall.

Mark the location where you want to install the thermostat. Drill a small hole in the drywall in that area, then feed the wire into the hole.

This comes from the transformer usually located in the air handler for split systems but you may find the transformer in the condensing unit. For this reason, it is a good idea to kill the power at the condenser and the air handler before changing or working on the wiring at the thermostat.

If you have a package unit then the transformer is in the package unit.

Average Home Makes 40 lbs. of Dust Yearly. So we all know how dusty the tops of tall cabinets get over time. Fibers from furniture and carpeting, dead skin, dirt from outside, pet hair, and the like build up .

When I removed the wires from the new thermostat, the HP kicked on. First lets get the HP and Furnace to operate correctly. Do you have a wiring diagram for your equipment? As I look at your last message you have W2 connected to the thermostat with a white wire that goes where? This is typically not used on a fossil fuel set up.

I am searching for a diagram right now, I do have a diagram I can send you but your FF kit could be different.

How to Install a New Low-Voltage Thermostat

As soon as I convinced my wife it was worth the investment, I went straight to Amazon Prime. When it started having trouble connecting it to my wifi, I realized my common wire does not have enough voltage to power the Nest! Most modern thermostats require what is known as a c wire.

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.

As another data point I actually got the sail switch working again – just had too much stuff built up on the sail, was staying locked “on” all the time. Cleaned and now works. If the sail switch happens to fail while I am still there I could just get a current sensing relay for the fan motor and switch the low voltage through that as well. My only concern is the added load on the heat contact in the thermostat. Not sure how much humidifier draws 24V in operation, nor what the thermostat contacts are rated for and I can’t take measurements until I get this operational again, still need to find what the correct water panel is for this unit.

I think it is unlikely the current is too high. In the good old days the thermostat had a “heat anticipator” that caused the stat to shut down heat a little early. The anticipator at the stat was set to the gas valve current. The current would be higher if you add the solenoid. This is probably not an issue with recent stats.
