The Lazy Daze Companion: Thermostats

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.

It is possible to hook up those other fancy smart thermostats, but it requires some serious electrical knowledge and additional parts. Plus, you will probably need more than one. Most people with high voltage heat have multiple thermostats throughout their house.

Old thermostat wiring

Homes like this are increasingly common. Dozens of builders are telling us this is happening. Or you can try using equipment designed for sailboats. The PassivhausA residential building construction standard requiring very low levels of air leakage, very high levels of insulation, and windows with a very low U-factor. To meet the standard, a home must have an infiltration rate no greater than 0. The standard recommends, but does not require, a maximum design heating load of 10 W per square meter and windows with a maximum U-factor of 0.

Additionally highlighting some of the differences in those functions from manufacturer to manufacturer. Wire is available here. Always turn the power off!

You can do this at the air handler and condenser. Always make sure there is no voltage at the transformer before proceeding. The thermostat wire colors below are the most likely colors used for most installations. However, your thermostat wire colors may be different than what is indicated here. There is no official standard for thermostat wire colors.


Post Nest introduced its smart thermostat in October of last year only to find that there was greater initial demand for its product than originally thought. It has taken months for supply to catch up. Essentially, the Nest thermostat should look good when you see it and manage your environment automatically in the background. Does it achieve that goal? Advertisement Nest Installation is a snap My home is relatively new; only about 8 years old and I had no problems installing the Nest.

The connection that the thermostat makes to start the furnace is the R to the W on the furnace, so we need the thermostat to be able to do that for two separate furnaces, so what we do is have the thermostat make a DPDT relay that tin turn makes both furnaces R to W connection, I can .

As Carson Dunlop Associates ‘ sketch left explains, there are a number of places where you should not locate the room thermostat. Bad Room Thermostat Locations Don’t locate the room thermostat in these locations: Their heat may affect its operation. Room Installation Thermostat Installation Tips Use new thermostat wires to avoid the risk of insulation nicks, cuts, and shorts in old wiring Seal the hole in the building wall through which the thermostat wires pass out to the thermostat mount.

Drafts through wall cavities can blow out of this hole and affect proper thermostat operation. Do not use the thermostat power transformer to operate any other devices such as doorbells Does the Room Thermostat Need to be Level on the Wall?

With a zoned heating system you can turn up the heat just where you need it, just when you need it—resulting in significant savings on your utility bills. Read on to learn more.

Below we will describe to you how to hook up a digital thermostat, hook up a programmable thermostat, or hook up any type for that matter. Whether the old thermostat is bad or not if you simply want to replace your old one and hook up a new one the first thing you need to take into consideration is to select the right replacement thermostat. To select the correct replacement you need to know what kind of HVAC equipment you have in your home or where you want to hook up the new thermostat.

There are numerous types of air conditioner and heating combinations so in this article, we will cover a basic gas furnace and air conditioner split system HVAC system. Thermostat Wiring Colors Code – Learn More about the Thermostat Installation opens in a new window How to Hook Up a Home Thermostat If you do not know what kind of unit you have to take a look at the paperwork from the last time the unit was serviced. Perhaps it will show the type of equipment on the service ticket where the unit had maintenance.

It is assumed that most people will know what kind of unit they have so that they can select the proper thermostat.

Furnace Not Working

Podcast Network January 27, You are here: The DIY market has always patronized the Home Depots and Lowes from the day they bought their first house and the DIY market has never belonged to any distributor or contractor, but the potential of Nest to impact our markets beyond the DIYs bears conspiracy, I mean, considerable attention. Although, a twenty dollar Starbucks card goes to the first person who correctly identifies the third largest stock holder in Nest in the comments section.

Top Zoning Thermostats Ecobee4. The ecobee4 is best for when you have a central low voltage heating system with only one thermostat. You can connect sensors to the thermostat and Ecobee will then make sure the rooms you are occupying are heated to your comfort.

Editor’s Choice Winner The Ecobee The multiple sensors really won me over, it makes so much sense to have an average temp across different locations in your house, especially if you have an entire floor on one heating or cooling zone. In my house there are rooms that are much cooler or hotter than others , so having the average temp ensures the heat runs until the entire floor is comfortable, not just the room the thermostat is in.

View on Amazon Before we dive into the reviews, we have a little crash course in Thermostats for you. You’ll learn how a z-wave thermostat works, how it’s wired, and how to replace your old thermostat with a Z-Wave thermostat like a pro. You can skip to detailed reviews here Home Thermostats Many older thermostats provided a single dial or slider to adjust the temperature of your home. They used a mercury switch a little glass tube filled with mercury to turn your furnace or air conditioner on.

2 thermostats for 1 furnace and ac unit

Connecting the stats in parallel. Will cause short cycling when both call at the same time. If each stat has the anticipator set as if there were only one stat, when both call there would be less anticipator effect half the amperage through each anticipator assuming equal resistance. When one thermostat stops calling the anticipator of the one still calling would become normal.

But, the one that satisfied first would cool down and start calling sooner than it would have if it’s anticipator had been working normally.

Depending on the heating system you have, you can have from two all the way up to eight wires that run from your furnace to your thermostat. Two wire thermostats are heating only thermostats. These thermostats have two wires, typically red and white, that run from the furnace to the thermostat.

If you have single-stage electric or gas heat, and single-stage air conditioning, the terminals with wires attached on your old thermostat may be: If you have a single-stage heat pump system with electric back up heat, the terminals with wires attached on your old thermostat may be: Disconnect wires and remove base After labeling the wires, remove one wire at a time from the old thermostat base and secure it by wrapping the wire around a pencil. This will keep the wires from falling into the wall.

When all of the wires have been secured, remove the sub-base from the wall. Install new thermostat base Mount your new Sensi thermostat base using the supplied screws, drilling holes if necessary.

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.

The thermostat load wires are the ones in the center. To attach two systems to one controller you would take these two yellow wires, and if this were a system these would be red. You can see that we also have two black wires, and we also have two green wires.

Supply side installations typically duct the evap cooler into the supply plenum. They often “work” OK because 1 some air makes it out the supply, 2 some forces its way back through the furnace and exits from the return air grille, 3 owners have low expectations. Return side installations typically are ducted into the return duct and have a manual “damper” of some sort that blocks air from the furnace and forces it out the return grille. In both cases the path of the air through the house is controlled by which windows are opened for pressure relief.

I’ve never seen either version done well enough to keep from losing massive amounts of efficiency during heating because of poor work on the evap cooler ducting connections. I’ve seen situations where cold air was being drawn through a poorly sealed evap cooler into the return ducting, which brings in cold outside air that has to be made up for by forcing conditioned air out of the house – a double whammy.

I’ve also seen very badly damaged ducts from the evap cooler water. While the normal air from the cooler may or may not be OK in metal ducts, oversized blower motors which some put in to get more cooling from their units , or problems with the water distribution system often allow more than expected amounts of water into the ducting. You are probably moving – cubic feet per minute of air with your evap cooler.

Your ducting system probably isn’t going to properly move any more that about half of that if it’s typical. I wouldn’t try it, and I wouldn’t hook it up for a customer. If you want to try it, I would recommend: Inspect the “stub” of duct that you’re blocking at the outside wall while the heat is on to see if it’s leaking somewhere you don’t really want to put heat. To some extent you have to get used to it.
