5-1-1 Day Programmable Thermostat for Home Conventional Single-Stage Systems, up to 1 Heat/ 1 Cool, (with White Backlight)

I have 30 yrs HCAC experience, and I am SO impressed by this t-stat. I tried this on a whim because it's the first t-stat I've seen in years with the 24v power option that didn't cost $100.First impressions when I took it out of the box: It felt solid and had some weight to it. Totally unlike "light-weighted" Honeywell junk that is over-priced to begin with. Buttons are solid with affirmative feedback when pressed.I wired it up to operate without batteries (hooked-up the 24 volt common). Extremely pleased with its operation. Backlight is a pleasant soft white with easy-to-read display suitable for my aging eyes. Menu is well thought out and easy to navigate.The Tech-level adjustments are well executed as well. I was really excited that it even has a thermometer calibration feature in addition to the Swing adjustment. Very smart the way they separated these Technician level adjustments separated from the homeowner-level/programming adjustments so the homeowner doesn't get in over their head or screw something up.I also tested it running on batteries. Ran just fine. Battery life is unknown since I'm only using batteries for backup. I'm also impressed with the battery access. No need to remove the t-stat from the sub-base to access batteries like many of the flimsy Honeywells. This Heagstat has an easy access panel on the front.This is the nearest thing thermostat Valhalla I've come across in years. I purchased 5 more just to have on hand. The only thing they could possible add that would make it pure Valhalla would be to include a Plain-Jane hour meter (in addition to the filter hour count feature).Solid 5 Star product.

Easy to program and control temperature. It is great quality for a great price. The accuracy of this product is perfect for any household. I recommend this product .I have 2 and they work perfectly on both floors.

Arrived quickly in good shape. Easy to hook up as my system only uses two wires. That means the thermostat has to have the batteries to function. Works great after figuring out the correct programming and offset for temperature. Back light is a great feature because you don't need to turn on a light to see the display. Directions were good but not great - otherwise very satisfied.

With so many different thermostats that's available I was glad I chose this one. It was very easy to program once I put the batteries in it I was able to actually sit in my chair and program it without having to stand and do it by the wall where I mounted it. It was very easy to install the wiring diagrams were perfect. I like the size of the LCD display it works flawlessly I couldn't be happier especially at the price point that I purchased it for I would highly recommend this unit for anyone looking for a quality thermostat replacement

For years, we had issues with our heater not staying on until we purchased and installed this new thermostat which solved all our problems. I love that it is bright and clear with big digital-light display. I love that the batteries are in front to be replaced so easily. I love how easy it was to install and worked without any issues.

My old two heat stage Honeywell thermostat no longer always energized the heat, must have been a problem with the relay contacts. Looked for a replacement 2 stage thermostat and found this one. Although it is not the latest WI-FI enabled, it does what is needed. It is programmable for MON-FRi, and SAT and SUN. The nice thing is that there are adjustments for temperature calibration, cycle rate, and more. (The Honeywell was known for short cycling). There is no info in the book as to when the second stage heat is called on, but it seems like if you are more than a degree below the set-point the second stage is enabled, when the second stage is called for the number +1 appears above the heat symbol. Another nice thing is that it is powered from the heater but also has battery back-up, not like my old Honeywell that did not have battery backup, so with a loss of power I needed to reset the time. I did inquire to HEAGSTAT as to when the second stage was activated, as at one point it seemed like it was always calling for two stage heat. Their reply was disappointing, basically saying to hire an electrician. I would have liked an explanation of how the second stage is energized and info that when it was energized the +1 would appear. The manual also shows a +2, who knows what that is for as there is no info in the booklet. The thermostat so far seems like a great deal for the money, works well and has many adjustments, and is for two stage heat and cooling. I give it five stars, although the customer support was disappointing and a bit insulting.
