Rather impressed with this thermostat. Replaced the big analog black one fairly easily. Thanks to other reviewers, the wiring was very straight forward. If it continues to work well, I'll be ordering another for my second AC.

Defective product! So disappointed. It comes to life but causes the furnace to turn on and off repeatedly. Customer return not accepted, even if defective.

We updated from the older thermostat to this newer one - very happy so far, especially with the backlighting.

Size of unit is quite small. I was hoping it would have covered the old holes, but it still works fine.

This product arrived with the package open, no instructions, no wires. It is much smaller then the Coleman Mach it is supposed to replace. Amazon says product can't be returned but they will credit buyers.

Reçu article déjà ouvert et utilisé. Un bornier (ground) est brisé… Pour le reste Le thermostat semble bien mais décevant à ce prix d’avoir un article cassé

I wasn't expecting this to come with no retail packaging or instructions, it was just in a sealed bag. The thermostat appears to be brand new tho, and I was able to download product info/instructions from the Coleman Mach website. Installation was not straight forward. This new unit uses 20 AWG solid wire, unlike the old one. So I had to purchase the new wires, and then connect that to the existing wiring in the wall. It works great, the thermostat is a huge upgrade, but it involves a little more installation work than I was expecting. Just a heads up of what to expect.

They must have sold me some that was already returned. This thing turns on and then soon as you set the heat temperature it turns off and the Heat obviously turns off. This is horrible product and there's no returns to yeah they sold me garbage and made sure there was no returns. Do not recommend this product nor do I recommend this seller! Do not buy from these people definitely do not buy this product. It will not work for heat only situations. I don't know about anything else because I already installed the heat pump for my AC. But this will not run my propane furnace. Garbage let me repeat myself garbage. Save yourself don't buy this crap and don't deal with the frustration I'm dealing with. I have two brand new holes in my wall for this garbage.
