1F85U-42PR

Bought to replace dying Honeywell tradeline Chronotherm T-stat. Simple to install & program and has needed features without going the smart route. Installed during peak cooling season and now well into heating season it works excellent. Holds temps both heat & cool with no short cycling. Great non smart T-stat for a great price.

This is the easiest programable t-stat I have ever used. I had it in a hotel and decided I needed it for the house. The screen is bright when you need it but blacks out quickly when done. The numbers are also nice and large. It’s default if a 5 day a week program (M-F) but the instructions to change either to a 7 day program can be found in the ”installer” program instructions. Not the “user” program instructions which is not obvious but do-able. Bottom line: It is perfect.

This is a replacement for my 20+ year old Lux programmable that although still operating correctly was having failures in the hold mode and setting the time. Programming this one was pretty much similar. The only difficulty and the most time consuming was on installation trying to attach my two very old wires (cloth insulated) into the sideways slots. Front approach which Honeywell seems to have would have been easier.

It works great. I bought this one because you can set the temperature differential that others cannot. This is important because modern thermostats are so sensitive that the furnace runs a lot. They keep very accurate temperatures in the house, but at a cost of fuel efficiency. This helps a bit in this regard. I did have to adjust the displayed temperature because it was not in-sync with the thermostat, but that is why they allow you to adjust it. I ran a C wire so the light could be used to stay on constant and so the battery would last longer. This worked well. I left the light on for the first couple of days, but later change the setting so I could press the button to turn it on. I will use the on all the time feature, however, when I have guests because it doubles as a nightlight in the hallway. Programming for only two times per day was confusing at first because of the labels they use for the two times. It seems backwards. Once you figure that out, it was easy to set the programming. I did not need to set a change for 4 times, but it is able to do that. The display is large and the buttons make it easy to use. I purchased this thermostat instead of the smart ones because I do not trust anything connected to the network for controlling my house. They do have issues and safety is one of them. I like this one because it is programmable and simply works once it is configured. You set it and forget it. Another thing I like is that it does not have a touch screen. Many reviewers stated that touch screen thermostats all eventually die. I wanted to stick with buttons for reliability.

Great thermostat. We chose not to get the WiFi connected Emerson version because we didn’t need it. (We wanted a “simple-to-operate” and it is! ). Brand is actually White Rodger’s/Emerson.

Love it the plumber put in a Honeywell T6 Pro Thermostat and I hated it!! The t-stat was too dark and hard to program for me. I am glad I got this Emerson it has a 5 year warranty vs 1 year on the T6 pro, you can see it without a flashlight in fact you can leave the back ground light on which I do for kind of like a night light. Really easy to program has the button for heat, off and cool on the bottom like my old one was so you can switch to heat and cool without going to a menu. If you want to have have 2 programs each day use the 5-1-1 instead of the 7. Example I use 7:00 am for 71 degrees, and night 10pm at 68 degrees this is for Monday - Friday don't have to program for the whole week since I use this for M-F, and on Sat and Sun you set it for 2 times like you did for the week really easy!!! Note: I didn't install it had a handyman to it for me.

I got this as a replacement after sending the first replacement I received back (different model, different manufacturer). The directions are easy to follow if you are technically inclined at all. Programming was easy to follow also. This unit will hold the temperature right at the set point. If you need to make a temporary adjustment, just change the setpoint. It will hold for a few hours then go back on the regular schedule. We find this easy to use and does a great job. The only thing I can't address is the longevity but expect it may well be the last thermostat I buy.

FYI: Package had been previously opened. Pull tap to activate batteries had been removed and reinstalled because the tap to be remove was under the battery versus sticking out. (Had to remove batteries to remove the tab.) The thermostat had non factory settings programmed into it. Preformed reset procedure. Thermostat seems to be working correctly. I think new implies just that and not previously owned and returned.

Perfect !!

Remplacée car l'encien model est défectueux, installer nouveau modèle. Tous fonction bien pas de surprises.
