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.

Alexa gets smart about thermostats with new Nest-ready tools

R — The R terminal is the power for the thermostat. 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. Red for the R terminal. RC — The RC terminal is designated for the power for cooling.

how to hook it up to the most basic two wire install? Normally, comming from furnace, connecting red to white would control it. >>>> I am installing a new NEST thermostat, replacing an old two wire mercury bulb furnace thermostat. There are only two unmarked wires. There’s 24 V across the wires.

Hey all, I have a question that I hope some folks who know more than me could help with. I am looking to upgrade to a wifi capable thermostat for a 2nd home. The house is small, near the coast and has a 2ton WaterFurnace Envision series 5 geothermal cube. Since we usually only spend weekends there, and sometimes go long winter stretches without going at all, we usually set the Geothermal at 55 in winter and 76 in summer when we leave, and then bring the system to temperature 2 degrees at a time during the winter as to avoid the back up heat kicking in when we get back.

It would be great to be able to go onto the internet to turn on the AC or heat in advance of arriving, so we do not have to wait for the temperature to come up or down upon arrival. It’s especially bad in winter when it’s 55 and we have to bring it up to 69 2deg at a time.

Super Thermostat I have two heat pumps to heat and cool my house. The house layout is such that there is no path from one part of the house to another for a big old air duct and two of them offer redundancy in case of failure. I have really nice programmable thermostats on the systems that can shut them off during the peak period but there are still a few things that would be nice to have. Ability for each of them to know when the other one is on to prevent both of them from coming on at the same time, or restrict each thermostat to a specific period of time so they don’t overlap each other.

Be able to adjust both of them from the same spot so you don’t have to run back and forth. Be able to tell if either of them are on and what they are doing when wondering what is eating up the power. Keep visitors from playing with the temperature when they think they’re getting too hot or cold. Sounds like a job for a couple of Web enabled thermostats doesn’t it? Enter another Arduino, this time a thermostat.

How to Install a 2nd Generation Nest Thermostat

Smart Home How to install the Nest Learning Thermostat If you’re sold on conserving energy and reducing your bills with Nest, use this guide to install and configure your smart, new thermostat. Although it plays an important part in our comfort and energy bill, it doesn’t get much attention, ignored along with other utilities like the water heater and trash compactor.

Most times, we set it, forget it and get on with our lives.

The obvious answer is to run a new thermostat cable with five wires instead of trying to use jumpers etc that in the end just end up causing more troubles, like destroying a circuit board. In most cases if can be as simple as attaching a new one where the old one goes up the wall from the basement if it’s open.

But, is the release really that significant? Pros Larger display with better overall resolution. Far-field sensor for viewing temperature from a distance. Learning capability has been enhanced. Cons No remote temperature sensors. My Nest 3rd Generation Review The new Nest thermostat 3rd generation looks noticeably sharper right out of the box. And, the resolution has been enhanced to pixels per inch. What I will note is that this model is sharp. It has really been enhanced in the aesthetics department where it makes older models, such as the Ecobee3 or the Honeywell Wi-Fi Smart , look old.

Enhanced Learning Nest is the leader in the smart thermostat industry — and remains that way with the 3rd iteration. And, the learning has been enhanced. Farsight The farsight feature is great and uses a far field sensor to operate. What this does is ensures that you can see the temperature from a distance.

I chose the Worcester-Bosch Greenstar 30CDi combi-boiler as the heart of the system since the manufacturer has a very good reputation for reliability and efficiency. This boiler has various control systems that can be used to operate the heating and direct hot water. The DT10RF controls both the operation of the central heating, and also the timing of the hot-water pre-heat function which allows the boiler to deliver hot water more quickly. When running the heating, the optimiser function calculates the time the boiler needs to start in order to reach the correct temperature at the programmed times.

You can set up to four different time periods for each day of the week for heating. You can set the room temperature for each of these four periods.

A smart thermostat is a great accessory to have, not only to be able to adjust your home’s temperature from your phone, but to also save money on your utility costs. Here’s how to install and set up the Nest Learning Thermostat in your own home. Warning: This is a project for a confident DIYer.

Caulking Gun Step 1: Plan Your Wiring I could have continued to use the 2 thermostat wires that were in my wall plus add 2 more wires that will run outside the wall to a nearby outlet where I would plug in the 24vac transformer. I didn’t like this setup because I didn’t want the wire to the transformer exposed where the thermostat was mounted. The installation would look much cleaner if all the wiring ran through the wall as it did previously. I needed 4 conductors.

Two from the boiler and 2 from the 24vac transformer. I was going to run the 5 conductor wire from my thermostat down to my basement and then I’d splice 2 more cables in the basement. One set of 2 conductors going to the boiler and two more going to the transformer which will be plugged into a wall. I used the same 5 conductor wire throughout except for the connection between the boiler and new wire where I used the existing 3 conductor wire.


Recommended For You 3 With the damaged Honeywell thermostat faceplate removed I began by documenting where there original wires were connected, this is very useful later! Add a comment 4 I then removed the thermostat from the wall. Dang, I have a few holes I don’t feel like patching and painting, guess this means I’ll be using the included trim plate which is optional to install. Add a comment 5 The Nest came with a handy, tiny screwdriver to remove these wires.

Hive vs Nest thermostats Hive vs Nest thermostats There are lots of smart thermostats to choose between now, with Nest and Hive two of the best known and most popular. Here we look at the differences to help you decide if one of them is right for you. It’s Hive vs Nest. There are lots of smart thermostats to choose between now, with Nest and Hive two of the best known and most popular. We’ve tested many of the new systems in our best smart heating systems roundup. Smart thermostats are the biggest development in heating technology in three decades.

Instead of a primitive timer or indecipherable programmer unit, the new smart thermostats simplify everything as well as allowing you to control your heating using your smartphone — wherever you are. Since we originally wrote this article, Hive and Nest have released new thermostats, 2nd- and 3rd-generation respectively. Hive has also launched a proper multizone system.

The 3rd-gen Nest can now control your hot water tank and has a couple of other features including a bigger screen and support for OpenTherm. For more details, see our Nest 3rd-gen review Hive or Nest: These are slighly higher than the prices for the original Hive system. It works with any supplier and with most boilers. Each kit comes with a box that plugs into your broadband router, and another box that connects to your boiler to give it the ‘on’ and ‘off’ commands.

Also note that it may be against the law, code, or regulations to do this without a permit, or it might void your insurance or warranty. Check your local regulations before continuing. The Nest Thermostat is one of the most popular smart thermostats on the market, mostly thanks to its unique design and easy-to-use user interface. So if you tend to turn down the heat when you go to bed and turn it back up when you wake up, the Nest will learn this and do it for you, without you having to program it manually.

If you see a handful of tiny wires in all sorts of different colors, then you likely have a low-voltage system, but if you see only larger wires that are connected with wire nuts, then you likely have a high-voltage system.

How to Check for a “C” Wire. The simplest and easiest way to check for a common wire is to look at your thermostat. Detach the thermostat from the wall, and take a look at the wires that are connecting to it.

By the end of the month, you’ll be able to sync your Nest Learning Thermostat up with Alexa-powered gadgets like the Amazon Echo. Chief among these is the popular Nest Learning Thermostat, which you’ll be able to sync with Alexa-powered gadgets by the end of the month. Those APIs help third-party developers sync their smart lights or newsfeeds up with Alexa, and have already brought a number of bulbs and news services into the Amazon fold.

Amazon hopes that the thermostat API will have the same effect, and says that thermostats from Insteon, Honeywell, and Nest have already jumped on board. They’ll join the Ecobee3, which is currently the only connected thermostat that Alexa knows how to recognize and interact with. Hook it up with an Alexa-powered device like the Amazon Echo smart speaker or Amazon Fire TV, and you’ll be able to tell Alexa to turn the heat down, or set the thermostat to a specific temperature.

A trio of big Alexa announcements from Amazon pictures Thanks to the API, you’ll be able to enjoy those same controls with other connected thermostats. And, unlike Alexa’s “Skills” the voice platform’s apps , you won’t need to add any extra “invocation words” to your command in order to activate the Alexa-powered climate controls. You can just say, “Alexa, set the heat to 70” as opposed to saying “Alexa, ask Nest to set the heat to Two new Echo devices for Amazon’s Alexa 1: The first is a battery-powered version of the Echo that you activate with a button-press; the second is a wired gadget that always listens for your voice commands like the Echo does, but pipes the audio to an external speaker setup.

Now, the Nest and other thermostats like it can enjoy that same level of control. Alexa is getting smarter — and simpler.
