Upgraded Digital Non-Programmable Thermostat for Home 1 Heat/1 Cool Single Stage System, with Temperature & Humidity Monitor and Large Blue LCD Display

Works Great on Gas Fireplace
I had an old Honeywell programmable thermostat on my InstaFlame gas fireplace that the installer setup when the fireplace was installed. The fireplace has a 750 millivolt ignition system with a two conductor thermostat wire. I use this fireplace to warm the family room and since we have an open floorplan, it also helps with the rest of the house. I got tired of messing around with the scheduling and having a dim small readout. I saw this thermostat while I was browsing around and liked that it had a bright blue background, the numbers were much larger then the old thermostat, and there was no screwing around with time schedules. There are similar rebranded thermostats that are probably made by the same company. The wiring was very simple. All I did was pull the front off the old thermostat and remove the red wire from the RH terminal and the white wire from the W terminal and then removed the old base from the wall. Since I am only using this for a fireplace I removed the jumper between the RH and RC (RH heating and RC cooling) to allow for more room under the incredibly small terminals on the terminal strip. I did struggle a bit to remove the new Garystat cover from the base but with a little patience and gentle prying with a screwdriver the cover came off. I installed the thermostat wires under the new base RH and W terminals and mounted the base to the wall. The Garystat base mounting screw holes fit the old wall anchors perfectly so I didn’t have to drill new holes for anchors. I installed two fresh AAA batteries (batteries were not supplied with the new thermostat), set the toggle switch on the back of the cover to the gas position, set the Heat/Off/Cool switch to the Heat postion, and snapped the cover on the base. I didn’t mess with the fan switch since my fireplace has a thermal switch on the firebox that controls the fan. I did investigate the calibration, swing and other settings. I decided to not use the humidity display setting and left the others at the default settings. The fireplace came on after I adjusted the setpoint to my desired temperature and when it reached that temperature the fireplace turned off. There is nothing to not like about this thermostat. It is simple to install, simple to initially program, and I love that you can calibrate your room temperature display. I hope it lasts a long time but if it doesn’t I will probably buy another one. They are inexpensive and seem to work great. The box had everything you need to install this and, while having small print, the instructions were pretty good for the installation. The example wiring diagrams were pretty useless since my application was not for furnaces, heat pumps, or air conditioners, but a casual inspection of the wiring for the old thermostat convinced me that the Garystat would work. Shipping was quick and the thermostat arrived undamaged.Update: I saw this thermostat was on sale and decided to purchase a second one as a backup. It has been really great and is very accurate. I would recommend this to anyone wanting a great non programmable thermostat.

5 stars if not for the battery dying so quickly
This was easy to install and not too bad on your pockets either as it is not too expensive. It works well and is reliable but I do dislike that it runs on batteries and that when they die and they seem to die quickly the thermostat just quits working. First time it happened I was afraid it malfunctioned since it was insanely hot in here and then realized it was just the batteries. I will try different batteries and see if that helps it to last longer. I do like how it lights up and keeps an accurate temperature. It looks very nice in my home too.
