80 Series, Non-Programmable, Heat Pump Thermostat, 1F83H-21NP

fast shipping works great easy to set up well packaged

Well designed. Perfect for controlling my dual fuel system. Eliminated a fossil fuel control board in my system. Controls temperature extremely well. Integrated perfectly with White-Rodgers control board. The instructions could be more explicit regarding thermostat auxiliary heat calls, manual heat calls, and heat pump to furnace call back during defrost. This would be very straightforward to write up. I'm speaking as an engineer...

The best “dumb thermostat” I could find for my heat pump and air handler set up. Easy install and ability to tweak settings. Large display. Simple and effective.

I had the upgraded model of this and sadly that died after 6 years. The AC would just cut off randomly or cut off when it reached the set temp and never turn back on at all. I had to keep pulling the new batteries out of it and reset the thermostat to get the AC to work again. After much banging my head on the wall to fix the issue, I decided needed to replace thermostat. I had their smart model that is 95% just like this one but more $$$$$$$ and you MUST use their app to even set it up. This unit is basic, no APP needed. I was able to keep the base on the wall from their more advance unit, and just put thermostat in it's place. It fit perfectly! Love that it was backwards compatible with their other models. I hated that I only got 6 years out of their smart device, but I love the look and style of these units. It has AUX heat, and was able to get this model for a decent price. So far, 100% love it.

If you have a heat pump AC, this thermostat will make you very happy. I bought in early June but didn't replace my old one until early August because I was afraid to mess it up, I took photos of the old one (Climatouch) wires To make sure I have the right connecting terminals which I have 5 wires, red, blue, white, green, light red. Very fortunate I see the same color wires in this new one, took the old one off the wall, place this new one in， Turn the power on, bingo! Sounds easy? But I spent more time to figure out how to screw the thermostat into the wall because my old one has a bigger hole :( anyway, I gave myself a pad 9n my back, all my worries has been overestimated! Effect? This new one is very efficient, it maintains the room temperature whenever the room is getting hotter, the result is a very comfortable atmosphere all day and night! More frequently to kick on but much shorter period of about 5 min vs 20 min of my old one which won't kick on until there was a 2 degrees differential between the setting temp and the room temp, sucks! Go ahead, but this one if you have a heat pump ac, you won't be sorry :) by the way, I just received my electricity bill, there are 2 weeks of using this new 9ne but my bill is the same!

Simple instructions very easy to install. Been using for two weeks now the only reason for 4 stars is I waiting to see how long it last.

This is non-programable - and that is exactly what I wanted. Easy to set.

We had a thermostat that was replaced under warranty approximately 5 years ago. When that factory American Standard Thermostat was installed, we didn't know it was newly manufactured in 2004! So, when we needed a new thermostat I decided not to bother with a super expensive one and to go with an acceptable substitute. This fits. It's worked for the past 3 1/2 months and it was simple for a handyman to install and to use.

It just works. Programmable and smart thermostats are junk. This is better, the temperature stays where you set it.

Comme celui que j'avais bon modèle.

Marche bien

no possibility to have .5 it's 70 or 80 not 70.5

Commandé deux fois le même thermostat de Amazon. Première fois une boîte ouverte avec le mauvais item à l'intérieur! J'ai retourné l'article. Je commande un neuf. Je reçois un avec l'affichage défectueux et le racket à batterie lousse en arrière. Manque de contrôle de qualité à plusieurs égards.
