A Helpful Thermostat
Honeywell has been around a long time. I have used them before. My previous model lasted a long while, but started acting up so I replaced it with the current model. I like that you can tailor the temps to your life style. We keep our house at 68-69 degrees during the day and drop it down at 12:30AM to 65. We set it to come back up to 68 around 8:00 am. This saves a little on our oil bill so, we are pleased with this Thermostat.

Simply excellent!
I easily installed this thermostat at my cottage, in the living/dining area, which is warmed by 3 electric baseboard heaters. I found they were all linked, in the basement, to a voltage reducer which turned 240 volts into 24 volts. From this device, 2 thin wires (red and white) connected to the old manual thermostat. It was a simple matter to remove this thermostat and then connect the low voltage wires to the new Honeywell RTH221 terminals, marked R and W. Programming the new thermostat was also very simple since I only had to enter the time and temperature for wakeup and sleep and those settings were extended to every day of the week. I love getting up in the morning to an already-warmed up house, and not having to remember in the evening to turn down the thermostat before bed time. This inexpensive thermostat delivers everything Honeywell promises and is the perfect choice for anyone who doesn't care about different temperature settings for weekdays vs. weekends.

Works OK but needs a lighted display.
Fine product, BUT if you've ever had to get up in the middle of night to change the temperature in your bedroom you know how helpful having lighted display would be. The once proud Honeywell is changing. Check this out from their corporate website: "Over the last few years, you might have noticed former Honeywell Home products being presented as Resideo variants or completely replaced with Resideo." As is you have to flip on the room lights or carry a flashlight just to see the display and find the controls! The once-proud Honeywell would have added a light.
