Picture this: You walk up to your thermostat to adjust the temperature in your home, only to be greeted by a blank screen. You tap on it and press the buttons — still, nothing. Since your thermostat is the control center for your HVAC system, you can’t afford to go too long without it working properly.

Remove and replace the batteries from your Honeywell system as directed in the instructions for your specific model. The batteries may be within your battery compartment or control panel. Be careful to make sure they are correctly oriented within the thermostat. Once replaced, test the system for operation and responsiveness.

Your thermostat is the control center for your HVAC system. Programmable thermostats feature easy-to-read screens that allow you to program your heating and cooling settings and view the current temperature in your home. However, if that screen goes blank, you can’t do any of this. Honeywell and other brands of programmable thermostats typically show a blank screen when there is no power going to the wall unit.

A Honeywell thermostat will flash a low battery signal for about one to two months before the batteries in the wall unit run out completely. If you’ve been away or haven’t noticed this warning and the batteries can no longer provide power to the screen, it will go blank. This is easily fixed by removing the cover on the wall unit and replacing the batteries. You may have to reset the unit and reprogram your settings once the display returns.

If your thermostat is wired directly into your home’s electrical system, a blank screen indicates there is no power going to the unit, which means there may be a tripped breaker or a problem with the wiring. If the breaker controlling the unit hasn’t tripped, contact an HVAC technician or an electrician to inspect the wires. Sometimes a loose connection is enough to stop power from running to the unit. If this doesn’t resolve the issue, have the thermostat replaced.

We have a travel trailer that is only three years old, but when we arrived this past Summer to open it up we discovered the factory thermostat had failed. I called all around and was told I"d have order one and it would be anywhere from $80 - $130! For a cheap little thermostat. I decided to do some more research and found a few interesting articles online where people used regular thermostats like this one to replace the ones in their trailers. You have to be careful and make sure you get one that uses batteries like this one does since the trailer does not supply a "C" wire (or something like that) with voltage to run the thermostat. And be prepared to read some wiring diagrams and switch some wires around at the thermostat. The only other thing is my old thermostat had a switch for high and low fan, this one does not. The solution was to wire it for high all the time. You could wire it for low all the time, or you could order a small toggle switch and mount it to this thermostat with some knowledge of soldering and electronics, maybe a 20 minute job.

This thermostat is all electronic. The old one was more of a mechanical adjustment. I know under the cover it was really electronic, but there was a mechanical switch to set it to cool/off/heat, so when we were ready to leave I could switch it to off and feel comfortable that it was off, since this is basically a mechanical disconnect. With this new one it is electronic, so the off setting is just a digital setting, not a mechanical disconnect. Normally this wouldn"t be a concern, but I have a background in electronics and I stay awake at night thinking about stuff like this. And since we sometimes leave the trailer for a couple of weeks at a time, and longer in the Winter, I didn"t want to worry about turning itself on after a power outage, or maybe when the batteries start to die. My solution is to remove the batteries before we close things up to head home. The battery compartment is easy to access on the side and pops right out with little effort. So that"s just part of our process now and gives me peace of mind that the A/C isn"t going to be running straight for three months in the Winter.

This thermostat is not programmable, so you can"t tell it to set certain temps during certain times or certain days. For my use I didn"t want that functionality. This is simple, set it to heat or cool, and set the desired temp, and you"re done. No 120 page manual to ready just to turn the A/C on.

TH401 thermostats give a modern touch to your home. With maximum loads at 120 and 240 VAC, these compact thermostats feature TRIAC operation that is ideal for small-space electric heat applications.

Since the Nest Learning Thermostat launched in 2011, no other smart thermostat has emulated its core function — learning your schedule and adapting to it automatically, so you don’t have to lift a finger. This feature has made the Nest one of the best smart thermostats (lots of) money can buy for years. But just a decade on, Amazon has finally done it. The online shopping giant’s $60 Amazon Smart Thermostat can intelligently determine if you’re home, away, or sleeping and automatically adjust your climate to keep you comfortable and potentially save you money. And you don’t have to program anything.

Amazon worked with Resideo (owner of the historic thermostat brand Honeywell Home) to develop the thermostat, and its internals are very similar to the Honeywell Home T9 and T5 smart thermostats. It’s compatible with most 24 volt HVAC systems (you can check compatibility here), but doesn’t support systems with more than three stages or multi-speed fans. Together, Amazon and Resideo seem to have finally cracked the smart thermostat conundrum, and the Amazon Smart Thermostat’s learning feature — called Hunches — is very good. No, it isn’t quite as good as Nest’s, but it also doesn’t cost $250. So, tradeoffs.

Hunches — which are part of Amazon’s broader Alexa smart home platform — are AI-driven decisions that use data from your Alexa smart home to decide what to do with your temperature. It follows, unsurprisingly, that the more Echo smart speakers and displays you have in your home, the better it will be. According to Amazon, Hunches also uses “select other smart home devices like lights, locks, and sensors” to determine if you are home or away, as well as geolocation of yours and your household members’ smartphones (everyone has to have the Alexa app installed and location settings turned on for the thermostat).

For the next three days, it turned on the heat a little too early, and I had to go into the thermostat settings in the app to tell Alexa its Hunch was wrong. After three times telling it that, no, we do not wake up at 4:31AM, it reverted to our regular wake-up time.

The controls on the Smart Thermostat are three touch points on the bottom. LED icons show you the ambient temperature by default, then the current set point when you tap on one of the arrows.

It’s hard to quibble much at this price, however, because at least it’s trying to be smart. Outside of Nest and Ecobee, few thermostats are actually smart. Most are just controlled remotely — either by an app, voice, or geolocation (where it adjusts based on whether your smartphone is at home). This is all very handy, but it’s not intelligent.

Case in point, the new Nest Thermostat has no advanced AI features of which to speak. While it can do useful energy-saving or comfort-increasing tasks such as preheat or cool the home or use the fan to circulate air to more efficiently use air conditioning, it doesn’t have the same learning features as the Nest Learning Thermostat and its smarts are largely reliant on Google’s home / away modes, which can use geofencing, on-board motion sensing, and other Nest smart home products to determine if someone is home. As with the Learning version, you can choose which devices feed into the home / away modes, which you can’t do with the Amazon Smart Thermostat.

If you don’t like the idea of Amazon controlling your climate willy-nilly, the Smart Thermostat has a standard scheduling option. With either set up, you can also use Alexa’s Routines to have your thermostat do specific things based on time of day, when a smart home device tells it to (such as a compatible temperature or motion sensor), or with your voice. These functions are available to any smart thermostat that works with Alexa, but you will not find one as inexpensive as this one.

The closest competitor price-wise — the Wyze Smart Thermostat — is $80, and the Honeywell Home T5 and T9, whose hardware the Amazon thermostat shares, start at $120. Most other smart thermostats are over $100, including the Emerson Sensi, the Lux Kono, and then Ecobee’s and Nest’s start at $180 and $130, respectively.

Of course, almost all those thermostats work with multiple platforms. The Amazon thermostat only works with Alexa. And while the coming smart home standard Matter — which promises interoperability between ecosystems — may change that, Amazon has not confirmed that this device will be upgraded to support Matter.

While this thermostat is inexpensive, it doesn’t look cheap, unlike the Wyze Smart Thermostat, which has a plasticky feel and an odd, oblong design. The simple, clean design of the Amazon Smart Thermostat will fit in with most homes, and because it doesn’t have an LCD screen, it doesn’t scream “high tech” like others in this space.

Most of the setup and programming of the thermostat requires the Alexa app. And, as you’d expect from an Amazon device, it’s designed to be controlled with your voice. This makes it surprising that the Alexa voice assistant isn’t built in as it is in some of Ecobee’s models. Instead, you need to have a compatible Alexa device for voice control.

Physical installation of the Smart Thermostat is identical to that of Honeywell Home’s T9 or T5 and requires shutting off the power and wiring the base.

Integration with Alexa is straightforward and doesn"t require a skill or account linking. Setup and installation of the thermostat is similarly simple. You will want to check if your heating and / or cooling system is compatible first, however. And if you don’t have a C-wire, you will need to opt for the $75 version that comes with a C-wire adapter and plan for a much more involved installation. (C-wire is short for common wire and supplies power to your thermostat. Most connected thermostats need a C-wire to connect to Wi-Fi, which is a big power drain.)

Everything you need to install the thermostat comes in the box, including a screwdriver and handy labels for identifying the thermostat wires. The Alexa app guided me through installation very well, making it clear which wires should go where, connecting the thermostat to my Wi-Fi, and testing that everything was working correctly. If you are uncomfortable with wiring or aren’t familiar with how your heating and cooling system works, you should get professional help. Messing up your HVAC system will be a costly mistake.

Using the Alexa Smart Thermostat was a smooth experience. The Hunches worked well (other than my 4:30AM blip), turning my heating down between 11PM and 11:30PM every night and back on at 6AM in the morning. Switching to away when the house was empty during the day was less reliable, and in my week of testing, I wasn’t able to get a firm read on how long it takes to adjust to an empty home — this is a key component of any energy savings this device will get you, so I’ll update this review once I’ve had more time to evaluate the feature. However, you do have the option of telling Alexa, by saying “Alexa, I’m leaving” as you walk out the door.

Controlling the thermostat with voice using an Echo speaker or display was smooth — and with the latter, an interactive screen pops up for further control if needed. You can control the mode with voice, too, switching to heating or cooling, and even ask Alexa to change the temperature when no one is home.

In order to use the Amazon Smart Thermostat, you’ll need to download the Alexa app for iOS and Android. An Amazon account is required to sign in. By signing up for one of those, you must agree to its conditions of use.

Once you connect the thermostat to Alexa, you need to agree to Amazon’s conditions of use and all of the terms found here. You can explore the documentation at that link, but below, we’ve listed the 12 terms that you must agree to:

But the app was a more frustrating experience. It takes four or five taps to get into the thermostat screen, although eventually I was able to add the thermostat to the new Favorites section in Alexa’s devices page, which speeds things up a tad. Once on the correct screen, the controls mimic those of the physical device, plus there’s a humidity reading (the thermostat has a humidity sensor in it, a temperature sensor, and an ambient light sensor for adjusting the brightness of the LEDs).

The one other area I ran into issues with was using the thermostat in a two-zoned home. As with all thermostats, you need one for each zone in a multi-zoned systemand they control the climate independently.Butthe Alexa app wouldn’t let me set the home, away, and sleep temperatures separately; whatever I set for my upstairs zone also applied to my downstairs zone. That’s not ideal if you like to sleep at 66 degrees but want your living room and kitchen to drop to 62 at night to save energy.

Switching the upstairs thermostat to a schedule and keeping the downstairs on Hunches did allow me to have different set points, but that’s not an ideal solution. This is a problem in the Alexa software, as with every other thermostat I have tested in this two-zone system, each thermostat controls each zone entirely independently.

The other drawback is that there are no temperature sensors designed specifically for the Alexa Smart Thermostat. It’s possible to set Alexa Routines to use with the temperature sensors built into some Echo speakers or with compatible third-party motion or temperature sensors like those from Centralite and Aqara, plus Amazon’s new Smart Air Quality Monitor will work with Routines. But that integration isn’t as seamless or as easy to use as thermostats with native temperature sensors.

The Nest Learning Thermostat, the Ecobee thermostats, and the Honeywell Home T9 Thermostat all work very well with their own external sensors, but these thermostats cost $100 to $150 more than Amazon’s. You also don’t get useful extra features such as the time and weather displayed on this cheaper thermostat or integration with platforms or voice assistants other than Alexa. Still, if those features aren’t important to you, then you really can’t go wrong with this device.

Based on my testing, it’s hard not to be impressed with the Amazon Smart Thermostat, and not just because it’s cheap. I have tested almost every smart thermostat released since the Nest Learning Thermostat launched a decade ago, and this is easily one of the best.

I would still choose a Nest Learning Thermostat for my home because I love the look and feel of it, and I have more control over how it manages my home’s climate (plus it works with both Google and Alexa). However, I thoroughly recommend the Amazon Smart Thermostat over the new Google Nest Thermostat, which is a dumbed-down version of the original (something of a theme with Nest devices these days). Honestly, the Amazon Smart Thermostat is the budget thermostat Google Nest should have made.

If your thermostat is blank, the first thing you should do is check the batteries. Chances are, the batteries have died and the thermostat simply can’t power on. Replace the batteries and see if your thermostat turns on. If not, proceed to the next step.

Typically, thermostats are connected to a home or business via the main electrical system. Sometimes, the thermostat or another source of electricity can cause the breaker to trip (similarly to how a hair dryer can trip the breaker for example).

If you’ve checked the batteries already, check the breaker. If it the breaker has tripped, simply flip the switch back on and check if this restores the thermostat screen.

Worst case scenario, your thermostat is at the end of its life and simply needs to be replaced. While all thermostats are different, the average device has a life expectancy of about 10 years.
