Most Liked Positive Review

I like it, but know what you are buying.

Replaced a defective four wire Honeywell thermostat that worked intermittently. On occasion, the display would go blank and the heat would go on full-on. It wasn't obvious that the thermostat was defective. I initially thought that there might be a problem with the main controller since the thermostat had no battery and power was supplied from the main controller. I was surprised to find that this Honeywell Pro thermostat had a battery. Didn't know about the four wire (with battery), five wire external power option. Got it working with four wires and battery. I then discovered I had the extra wiring to supply power with the fifth wire. Now works great in five wire configuration w/o battery. Apparently, the thermostat I replace was able to "steal" power from a four wire configuration.

Most Liked Negative Review

A non-mechanical Thermostat of Honeywell quality

I needed a thermostat to supply the BMPlus Zone Control System with Temperature, Heat/Cool mode, and Fan settings only. The Zone Control should control the CPH, Stage, etc. The Installation Pamphlet documents a variety of setting, but not how to turn them off. Honeywell support will read the pamphlet with you (if they answer the phone) but not offer any additional help. They should have a flow chart available. Better documentation is needed.

Good thermostat

I have been using this thermostat for 15 years or more. I've had really good luck with them and they are simple. Older folks don't have any problem understanding them and they last a really long time

They work very well, very accurate.

This was a replacement for an identical unit that was damaged by leaking batteries. There IS a low battery warning on this model which I simply ignored too long -- entirely my fault. We have five of these units for our zoned radiant heating system. They hold the temperature within one degree (or less) of the set temp. They are used for heating only, since we don't have or need central air conditioning. (We are able to cool the house with two portable window air conditioners.)

This unit displays both the set-point and actual indoor temperature side-by-side. On the 'auto' fan setting, the fan should run only when the heating or cooling system is operating.

This could be a number of things. 1) The thermostat could be located in a bad place (too far away/in cold corner), 2)The thermostat could be defective, or 3) your furnace may have a stuck valve or switch. You may need to call a professional if it's too involved.

You can set the fan to run continuously, by having the fan switch set to on, or set it so that the fan only runs when the heating or cooling system is on, by setting it to auto - both using the fan switch on the bottom left-hand corner.

Remove the thermostat from the face plate (it's held on by plastic tabs) The batteries are visible on the back. Might help to download the instruction manual from Honeywell's website.

The manufacturer recommends that this be installed by a trained, experienced technician. This thermostat comes factory calibrated. You can find more information in the Installation Manual: http://s3.pexsupply.com/manuals/1277918330238/33869_PROD_FILE.pdf

You can install it yourself. The few settings that need to be done are clearly explained in the directions and they are very easy to follow.
