Won’t work with baseboard heaters. Must have missed it in the description. They were VERY good about taking it back. So a mistake for me but I’ll continue to buy from Amazon with confidence.

I haven’t opened the package yet, so I don’t know how many stars to give. I am surprised to see on the back of the package that it requires 2 AA batteries. Inside the package I found that if they run out, it’s no big deal.
I had an electrician install it, and was glad I didn’t try to follow the instructions myself as it took a while (not because of the unit but because the wiring in the house wasn’t obvious). I don’t have AC in the house.
I find the unit easy to use, not confusing, the buttons make sense. I didn’t want a lot of features, or weekend settings. A light would be nice–instead I have a nightlight mounted nearby.

Temp reads 3 to 5 degrees higher…woke up very cold 1st night.The reason I say 3 to 5 is because when I woke up it was 3 degrees off so I turned it up to where the furnace kicked on and the thing shot up about 5 degrees before the heat was on even a minute…so anyway the heat turns off and it’s still cold.Comparing the temp in the room with the old mercury thermostat and another digital temp recorder it was 5 degrees higher then what both of these said.I think it’s closer to 3 degrees off as it seems the old mercury type thermostat seems just a bit slower to react then these digital readers.After about 1 hour the old mercury thermostat is getting closer reading 74 while the honeywell is reading 77.

Thermostat is OK for the price. It programs easy, and seems to work fine. The reason for the two stars is that I ran across a scenario that worried me when programming the unit. I found that if I set the program and then manually adjusted the temperature, the “Heat” indicator on the display would be off, but the output relay would be On – causing heat demand – in fact heat demand that was uncontrolled. I tested this on two units and it happened on both. Pressing the “Run” button seems to kick it out of this mode, so I still use the thermostat.

This is a simple to use and accurate temperature control device. Clear display, easy to install.
