Comments about White-Rodgers 1F97-1277 Programmable 1 Heat/1 Cool Thermostat:
I own a small multi-family apt. building. Heating system heats the entire house. I didn't want the thermostat controls to be inside one of the renters' apts. I had an electrician install the controls out in the hallway (in a clear lock box) while remote sensor is inside apt. Voila, a perfect solution and money saver! Programming is easy.

Comments about White-Rodgers 1F97-1277 Programmable 1 Heat/1 Cool Thermostat:
I've had the White-Rodgers 1F97-1277 installed for about 2 weeks now and it is doing great. My connection has a common feed so unlike some reviewers I haven't experienced any problems seeing the display. Once you get the hang of the controls (read the manual), it's a breeze. The panel lockout is fantastic if you have other residents (a.k.a. kids) who want to constantly monkey around with the temperature setting. Hint: I'd recommend that you install the batteries and program it while sitting at your kitchen table or on the sofa so that it's easy to have the manual close before attaching it to the wall. Great product so far!
Comments about White-Rodgers 1F97-1277 Programmable 1 Heat/1 Cool Thermostat:
It Took Me About And Hour To Install And Program It, But That is Because I Read The Manual First Which Made It Go Much Quicker. I Am Very Satisfied With It.

Comments about White-Rodgers 1F97-1277 Programmable 1 Heat/1 Cool Thermostat:
I like the features of this unit that most other brands don't have. Such as Auto system switchover (from Heat to Cool as needed), separately programmable fan control, and the Cycling fan feature is great (the fan runs for 10 minutes every half hour, even if the heat or cooling doesn't call for it) that keeps the air moving in the house.
Installation and initial programming can take some time, but it is worth it.
The large display can be hard to read when it is not backlit, but touching the screen at the bottom (away from buttons) will light it up.

Comments about White-Rodgers 1F97-1277 Programmable 1 Heat/1 Cool Thermostat:
This unit replaces an 18 year old White-Rogers ComfortSet II and has many of the same features, but updated. Installing the base is easy, but the wiring connections have been so miniaturized they are awkward to fit. Control is precise. The large display has a lot of wasted space and could be vastly improved by a brightness increase on making a setting (like the old model) since otherwise the big screen is just too dim. We will update remaining units with this one, but wish more attention had been paid to the low lumens on the screen.

Comments about White-Rodgers 1F97-1277 Programmable 1 Heat/1 Cool Thermostat:
Unit is very good and is holding the temperature very tightly. It was easy to install and when using the hardwire power you can leave the light on if you wish to do so. I have not had the units do anything weird like one reviewer is describing, but I did find that you have to disable the auto programming in the setup menu for it to work. You can still set up your own program but it will not follow it if this setting is not turned off. I think that is the issue for the reviewer.
I also found that you can tap it in a non-active area when in run mode so the light turns on without changing any settings.
I mainly bought it for the automatic changeover and the random circulation when no call for heat/cool.
There are 4 things that make this unit less than perfect, but it is still the best one I have found.
1) Display is harder to read than many others. especially from a downwards angle
2) You cannot program the random circulation for certain time periods only
3) Does not display filter life remaining (but does show when time for replacement)
4) Does not track run time (My previous Lux did that which is handy when on a propane tank as I get an indirect reading for the usage).
Delivery was fast and accurate. Unit was double boxed and arrived in perfect condition.

Comments about White-Rodgers 1F97-1277 Programmable 1 Heat/1 Cool Thermostat:
We like to control our heat during the day and night. We still have not figured out how to remove the factory program and use our own. It will hold at the temp that it is set to.

Comments about White-Rodgers 1F97-1277 Programmable 1 Heat/1 Cool Thermostat:
Great thermostat. Love all the settings. One suggestion - turn off the light so that it only goes on when you touch it.
