    • Great thermostat!
Style: Thermostat
This thermostat works great, is easy to use and seems well made. Was easy to install and the setup was pretty easy as well. I didn’t want a fancy smart thermostat and this does the job it’s supposed to.

    • Great Value - Not plug &play
Style: Thermostat
This is a highly functional, high quality, great value unit that remains available at a discount price because it’s simply a few years old in design and not built for the smart home / phone app market. This is the 2nd one I’ve purchased and would buy again. I bought the 1st one 8 years ago for a different room and it’s never skipped a beat. This was considered a high tech unit until the world shifted to everything working from your smartphone. This is the perfect selection for a fully programmable thermostat for older system installs where there is no common wire or interest in smart home wifi capabilities. But this unit is not the easiest on the market to install or operate if you like to adjust from the schedule frequently and have users who have trouble learning how to use features beyond the on/off button. Lol. It’s not hard, but it can be annoying for those who struggle with technology to learn how to operate Using the menu options to shift back and forth between a programmed schedule and holds on set temperatures that you may want to temporarily set (until next programmed interval) or hold for longer by placing program on hold until “cancelling” back to the schedule. For installation,I’d rate this as moderately difficult. You should be comfortable doing an installation that requires a bit of knowledge and experience with home repairs. Honeywell rates this as requiring professional installation. I wouldn’t go that far but you should be familiar with HVAC common wiring (or comfortable reading and following instructions inclusive of multiple options) and HVAC configuration terms which are selectable through an old school software interface to set up the thermostat to match your heating and cooling system(s). For this 2nd unit I installed, I was setting up to two separate units and wiring for an oil furnace and central AC unit and got a bit confused. But I contacted Honeywell support via chat and they walked through the installation step by step and helped me to identify the one setting I had incorrect. If you are looking for a really simple installation and user interface with big numbers on an easy to use display, skip this one. But if you want a high quality and fully programmable unit that gives you the capability to move back and forth between a programmed schedule providing energy efficiency 7 days a week and temporary adjustments to meet a variety of individuals (or spouses) who frequently fluctuate from hot to cold, buy this one at a bargain price and value. ... show more

    • Easy Set Up Good Purchase
Style: Thermostat
I thought that my A/C system was broke & all I needed was a new thermostat! Worked good. Just wish I could figure out how to change it from celcius to degrees but it’s not that big a deal. Good purchase & easy set up!

    • Works as expected, good product.

Easy to install and set up, large display for easy viewing. Programmable, compact, and comes with a face plate behind it to cover any marks on the wall from previous thermostats.

They work well with my Navion on demand hot water pump. Easy to use and install we have 7 of them, replaced so that they are all the same. Keeps accurate temperature.

    • Does not maintain requested Temperature 🌡️ in °F.
Style: Thermostat
Installed and setup thermostat easily. Advanced Setup (ASU) was easy. Unfortunately, it did not maintain the temp I wanted. I set for 77°F, but the remp would drop to 72°F while the thermostat display indicated 77°F. Setting to 78°F / 79°F did not do much better, still 73°F. Raised to 80°F the temperature went over 80°F. I could live with it being off-temp costantly so I could set it high to remain at a requested temp, but no luck. My older T5000 worked as designed but the illumination nearly went out to make it nearly unreadable. I called Residio but they came up with excuses. I will return this one and try another. I don't need the programability. Maybe I should stick with the T5000. I will give it one more try. It's 96°F outside. At least I am staying cool, but why waste costly energy. Replacement arrived in damaged box and it didn't not work as well. Returned for refund. ... show more
