Honeywell Home RTH221B1039 RTH221B Programmable RTH221B 1

It was suggested we replace one of our thermometers to be compatible with our boiler. This one does the job. It’s lightweight, slim and does what it’s supposes to do. No problems whatsoever. Very easy to install.

Here the deal: We had one of those Commercial grade Honeywell touchscreen thermostats that usually do a great job, but we noticed the temperature in the house never seemed to keep, and would hear the unit, whether heater or ac, kick on quite a bit. We decided to do some research, and with a deal from our energy provider, we ended up with one of those $249 Nest thermostats. I was STOKED, like a fat kid with some apple pie. We got the Nest in, and I went to work. Like a Dad in bad joke bookstore. I've replaced many thermostats over the years and the Nest was a piece of cake. BUT, we discovered it had a malfunction, so after talking with tech support, it was getting replaced. SOOOO, back to the Honeywell. I went out to the garage and grabbed the oldie off the shelf, and as I was walking in, my Dollar Store flip flop got caught on the door jam. It popped the rubber thing out of the foam bottom and made me nearly fall over forwards onto the hard tiled floor. There i was, Rambo faced, screaming in slo motion, feeling the pain of my big toe hit the metal, when all of a sudden the Honeywell touch screen goes flying out of my hands, and flips, and turns, and swings, and screams, to the floor. BAM!!! Cracked screen. Out of Commission. No Goodie No More. Mad me. I dropped the ball, but it wasn't the ball man, it was my $150 Honeywell touch screen I had plans to put back onto the wall when we sold the house years from now. So there I was, at a cross roads, like Willow, but without Mad Mardigan there to take the baby. I broke my working thermostat, and was left with TWO broken thermostats. It was humid, then cold, then hot, then cold, then humid, the windows were open, they were closed, they were damned like Conan the Barbarian was. I decided to order THIS thermostat from Amazon. I got in two days, and the hookup was easy. Easy yo. I'm talking so easy, I thought about taking it for a drink and a meal. The thermostat works like a champ! However I now rec'd the replacement Nest thrmostat and this one is taken down, boxed up, and awaits its new homeowner in severla years whoever and whenever that may be. Pros: 1. Easy to install (C wire is Common and NOT used) 2. Basic use makes ti fun for all ages! 3. Basic programming is available, but nothing that is 3 pointer at the buzzer wow 4. Small, and easy to use Cons: 1. None. It works great and is easy to install

The Honeywell Home RTH221B1039 is a solid, no-frills thermostat that does exactly what it’s supposed to do. It’s easy to install, user-friendly, and provides accurate temperature control. The display is clear, and the buttons are intuitive to use. Perfect for anyone looking for a budget-friendly option that gets the job done without unnecessary features. Highly recommend for basic heating and cooling needs!

the installation instructions are useless, terminals W & R for 2wire gas central heating systems.

Estoy seguro que el termostato funciona perfectamente, pero yo no lo he conseguido. Además las instrucciones están en español y la programación cierto es que es muy sencilla. Mi aparato es Carrier, consulte las configuraciones tanto en Carrier como en Honeywell, pensando que era compatible con Carrier. He probado todas las combinaciones de cables posibles y no lo he conseguido. Probablemente sea culpa mía, solamente quiero decir a otros compradores que se aseguren de la compatibilidad antes de comprarlo. Muchas gracias.
