Great Value – Not plug &play
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.

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.

Does not maintain requested Temperature 🌡️ in °F.
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.

Works well
I maintain several rental properties and like to keep these on hand for units where they get stolen or damaged. This one works very well and supports a wide range of installation setups.

We had a garage heater installed in our new home and the HVAC contractor used a $3.00 thermostat that wouldn’t go any lower than 10°C. With the cost of natural gas these days that’s too warm for our needs and the mechanical thermostat was too imprecise. The pro T4 is perfect for our needs. There is no C wire with our system so the T4 is running on batteries. We have experience with this thermostat at another house we own with a garage heater and the batteries last at least a year. We can set the garage heat as low as 5°C which works well for melting the snow off the car.Note that the T4 pro apparently has a warranty only if it’s installed by a HVAC pro but the warranty is voided if installed by a homeowner. Worth the risk in my view.

I recently installed the Honeywell T4 Pro thermostat, and I couldn’t be happier with its performance. The installation process was incredibly simple, even for someone with minimal experience. It’s especially convenient that it operates on batteries, making it a perfect solution for setups with only a 2-wire feed from the furnace.The thermostat works flawlessly, maintaining a consistent and comfortable temperature throughout my home. The display is clear and easy to read, and programming the thermostat was a breeze. It’s a straightforward, reliable device that gets the job done without any unnecessary complications.Overall, the Honeywell T4 Pro is an excellent choice for anyone looking for a dependable and easy-to-install thermostat, particularly for older systems with limited wiring. Highly recommended!
