1H Programmable Thermostat w/ 72F Max

THE GOOD: I love the product's user design features. It is easy to input four daily customized settings for weekdays, Saturdays, and Sundays. The display screen is easy to read once activated, and unobtrusive in its normal dark mode. We do not have air-conditioning and the absence of that function on this thermostat reduces its complexity. It is easy for a chilly guest to turn up the heat, but that change is limited to a maximum of 72 F and reverts to your programming at the next daily mode change. Setting up the program is relatively straightforward and should resist inadvertent tampering. Users can adjust the thermometer calibration. This allows for finer temperature balance in applications with multiple zones. No smartphone. No wifi. The unit looks nice and works reliably once installed (except as noted below). Great price. THE NOT SO GOOD The control display does not show what temperature the unit is currently requesting. This would be useful information. Surprisingly, a unit with so many good design features misses the mark on this one. We ordered seven units. They all came with two AAA batteries separately packaged. The batteries had big-name brands but looked very shoddy. The batteries in three units leaked in their original packaging. Another set did not have enough charge to set up the initial programming. We ended up replacing all of the batteries. I suspect the batteries that came with the unit were unauthorized knock-offs. Two of our seven units failed within one day of installation. The symptoms were the same. We entered the initial program. We installed the unit. Everything looked good. Then we tested by calling for heat and ending the call. Both units failed during the relay-switching process. They began flashing continuously and, despite numerous attempts, we could not reset them. Supply House provided two replacement units, and they work fine. THE BEST Supply House customer service.

I wanted a really simple programmable thermostat for an in wall gas fireplace with fan. Not a smart or enabled device. Not super expensive. Simple replacement for one from the 1970s. Surprisingly difficult to find. I called. Got great advice and I'm extremely happy. I'm going to buy again.
