Emerson 1F85U-42PR Universal (Up To 4H/2C) Programmable Thermostat

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

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.

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.

Perfect !!

Very easy to install.
