Aprilaire 8920W

Pros: emailed temperature/ humidity alarms, hardwired OA temp sensor, dual fuel compatibility, controls humidifier and air cleaner, Wi-Fi enabled, Geofence capability Cons: might be difficult for those that aren't handy to install, difficult to get connected online, screen is always on (but does dim). Overall, we are happy with this little gadget. The screen looks great and it is easy to use. Installation was easy enough to do. This model has a wired OA sensor instead of relying on internet for local weather data. Nice feature for vacation homes that might not have internet year round. The full color touch screen looks really nice with the black frame. While the physical installation was easy (I used to do automation systems) some folks that aren't too handy might be overwhelmed with all the wiring for the HVAC and humidifier and air cleaner. The real downer was getting it connected. It simply would not connect when using the app as instructed. I found that connecting the Stat manually through the touch screen got it online. That got it an IP address. Then I disconnected it from my router and went back into the app. Worked fine that time. I can only guess that something internal was not allowing it to obtain an IP through DHCP when using the app. Once it had an IP by connecting through the screen, it kept that reservation so it would work with the app.

Works great.

Really happy with this thermostat. The touchscreen is easy to read and use, and I like being able to control everything from my phone. It has a lot more capability than a basic smart thermostat, especially if you have other indoor air quality equipment connected. Once it was set up, it has worked great and been very reliable.

This is a good Indoor Air Quality (IAQ) device. Consolidates various equipment well. Disappointing in other functionality and user interface. I seriously question the $320 price tag because of the negatives below. Positive: 1. Easy setup - easily connect and control various devices. Took me less than 2 hours to connect furnace/ac, Humidifier and air exchanger. This is a BIG plus and the major reason for me to buy it. 2. Ability to control devices from phone. 3. Thermostat has a screensaver function that can show the temperature and time. Very convenient. Negative: 1. Outdoor temperature/humidity sensor needs physical wiring. Hard to do if you don't have easy access. I expected the equipment to pull outside data using WiFi function, in the absence of the physical sensor. 2. WiFi interface is extremely disappointing. I haven't seen the weather functionality work yet after a couple of weeks. 3. You can connect the display to WiFi without the app. However, the device guides you to install the app on your phone. 4. The app interface feels old and scattered. Needs a big face lift. The app also insists on having location on at all times. I sense some serious data collection. 5. HUGE NEGATIVE - The thermostat reverts to default setting whenever power is lost. I turn off the AC unit's power ever time I change the air filter. This is a BIG hassle. I have to reset the date, time, schedule settings every time! 6. There's no air filter change reminder option. Big minus for me. Timely Filter changes are important and the thermostat will be an appropriate place for the reminder.

An awesome thermostat in every respect. Big beautiful color display with all the important stuff on the front screen. Simple hookup with only 3 wires between the thermostat and the controller (mounted on air handler). Has connections for everything you could want (Humidifer, Dehumidifer, Fresh Air intake, Electronic Air filter, multiple temp sensors). The display quality is top notch, and installation was a breeze. Most of the negatives you might see (in other reviews) are due to a lack of user knowledge rather than any kind of product shortcoming. The one thing I will say is that the intial setup utility where it attempts to set up it's own wireless network and connect to it leaves a bit to be desired. I highly recommend manually connecting the thermostat to your existing home WiFi from the front panel of the thermostat (not from the app), and then adding the thermostat to the App (manually) by entering the MAC address that will be displayed on the front screen of the thermostat after you connect it to your Wi-Fi. I did have a single occassion where the thermostat seemed to think there was no internet after exiting the installed menu (it reboots). I simply rebooted it a 2nd time and it was fine. For those complaining about difficulty staying connected to your WiFi, please keep this in mind - the WiFi antenna is inside the CONTROLLER, not the display part of the unit. This means you need to have a good wireless signal where your air handler is located - having strong signal near the thermostat display is not relevent. You might need to add a WiFi booster in the area of your air handler, especially if it is in a basement, or garage.
