Perfect Thermostat for Baseboard Heaters
I replaced some old baseboard heaters (individual thermostats on each unit) and wanted a wall mounted programmable thermostat that would control 2 heaters. This Honeywell unit fit perfectly. It's power is supplied by its AA batteries so no power is needed from the baseboard heaters. I chose to use low voltage wiring to connect to the heaters, so the small wires could be buried easily without tearing up walls. The only negative is that programming isn't as flexible as other thermostats. There is only one daytime temperature and one nighttime temperature to choose from when programming the unit for automatic operation.

Unable to program, instructions poor in this area
Made two separate purchases. Units arrived quickly and in apparent good shape. Installation was easy. These replaced mechanical thermostats in an oil hot water baseboard heater system. They do a great job controlling temperature. I want to program them for only one temperature during the entire day and a lower temperature at night but cannot. The night time mode starts when I want but the daytime mode does not. The instructions have not helped. I wonder if I should try with the units in 24 hour clock mode.

This is an excellent thermostat, great value for the cost.
I use this thermostat for self generating millivolt control circuits. This is ideal for through the wall heaters and boilers which operate on 750 millivolt control circuits. Just 2-wires, no additional power required.

Limited funtionality
Although a 7 day programmable thermostat, you can only program 2 temperatures for all 7 days. The only thing you can program is the time to raise and lower the 2 preset temperatures.

Constantly making a loud clicking sound.
This unit constantly makes a loud clicking sound. My wife is bothered by it more than I am but now I am hearing it now. Annoying!

Very Easy to install and set up 120 volt thermostat.
My Sister's house had a unique setup. They ran 120V from the circulator motors to each thermostat. She had some ancient Honeywell thermostats that weren't working too well, and had no programmability. The only negative I can think of is that there are only 2 settings. Some of the other programmable ones have 4. The display is nice and large, and the Portrait format covers a lot of the older thermostats very well without having to touch up the wall paint. It screws right into the switchbox using the same screws.

I would use this product again for this application.
Someone install the boiler system in an apartment building I serviced. I heard from the owner that the pump couplers have been failing on all the pumps. I noticed the pumps short cycle the lot. There was no pump relays. 120 volts went right to the thermostats to turn on the pumps and they would short cycle 100 plus cycles a day. This inductive load digital thermostat solved the problem!

Great product, great service!
This is the absolute best 120v line voltage thermostat.
I am using for oil fired boiler where there are limited choices.
After using inferior other brand thermostats I called Honeywell and this was the recommended product.
Will not disappoint and easily fits into electrical box.
Ordering a second one for second zone today.

Great product. I would certainly buy it again.
I'm using this thermostat to run the fan in a toe kick heater, it was the only unit I found that used an actual relay for output control, not electronic based. It's battery operated so there was no issue with lose of power from the open circuit from the temperature limit switch on the heater. I would certainly use it again.
