    • Fixed my problem
Thermostat is just like the one I previously had installed. Works great! Fixed my problem of not being able to change temperature in house

    • My favorite
Have three of these in the house. They have been sold under three different names over the years but all are the same. Simple, basic, minimal buttons and they remind you when to change air filter. That’s my favorite feature!

    • Ideal direct replacement for one that looks like it
Purchased a Hunter thermostat over 10 years ago that looks identical. Old buttons were sticking. This is a perfect replacement; I just replaced front head unit, leaving existing back plate wiring intact. Works perfectly!

    • I can't imagine a better non-programmable thermostat
When I was converting my old HVAC system from full line voltage to low-voltage digital controls, I bought this thermostat to control the relays I used for the conversion. One of the features I like most is the adjustable "span" that controls the temperature differential between shut-off and turn-on. During moderate weather, you can adjust the span to 1 and the set temperature can be maintained very closely without putting an undue burden on the system. During more extreme weather, you can set the span as high as 3 degrees for wider temperature swings, to avoid the short-cycling that can reduce the life of your HVAC system. Many thermostats don't have this feature. Another feature I like is the blue backlight, which also stops working when the batteries are low to conserve power. And speaking of batteries, I like that it uses AA instead of shorter-life AAA, and I don't have to disassemble anything to replace them because they're right behind a door that swings open from the front. The one design feature I find somewhat odd is the fact that they located the filter replacement reminder reset button so prominently (the small button) on the front, instead of behind the door, but the good news is that resetting the reminder requires pressing and holding the button for 3 seconds to prevent resetting it accidentally. Finally, I'll mention the main reason I was looking for a thermostat in the first place. I already had a Honeywell thermostat that I had bought for my low-voltage conversion, but in testing it I discovered that it was just too sensitive to transitory temperature variations, such as even minor handling of the thermostat case itself. That's something you can't know until you actually make the purchase, and luckily I found that the Supco strikes a better balance in this regard, with a few extra features thrown in. Can you tell that I'm delighted with this thermostat? The whole low-voltage conversion was a bit of a pain, but definitely worthwhile, and even more so because I found the right thermostat. ... show more

    • RV workaround for automatic heater firing at 41 deg. and below.

Works great. For RV use BE AWARE IT WILL ALWAYS FIRE THE HEATER AT TEMPERATURES 41DEG AND BELOW!!!, even if it is turned off, and even if the batteries are removed!!!! This is noted on the owners manual under "Mechanical Heat Backup". Not so good for us up north where the RV is outside all winter. You must remove the thermostat from the wall to prevent this. To permanently disable this feature you can remove the bimetallic switch from the thermostat. To remove the bimetallic switch, remove the thermostat from the wall/backing plate and turn it over. There is a large silver colored square device soldered to the lower left corner of the circuit board, below where the batteries are. "SW5" identifies it on the board. If you look closely it has "5 C" stamped on it. (Of course 5deg C is 41deg F). You can carefully snip it off where it is soldered to the board, or I just snipped one leg off and bent it up to break the connection but left it there in case I ever want this feature back. This is a good safety feature for household use in that it will still keep the heat above freezing even it the batteries die in the thermostat. ... show more

    • Not the same as my old one
This thing is useless. I have used this exact same product for the last nine years with problems only occurring in the last two months. I know exactly how it is supposed to operate. It’s tricky, but not impossible. Until this unit… The temperature can never be made exact. The up arrow — even when touched gently — races up to a much higher temperature than you want. Then you are stuck with that one. I know to wait until it blinks to make a change, but the controls are basically useless. You cannot go up one degree; you have to go up three or four degrees. I actually touched the down arrow and the temperature screen showed the temperature going up! I bought this for $33 only 10 days ago. At that point it was an Emerson Climate Technologies product. Now in such a brief time apparently it has been sold (or rebranded) to Supco, and the price has significantly increased. I would suggest that you do not buy this product. Something fishy is going on with the company, and the product itself is junk. I could not contact customer service via telephone or email. Emerson is a HUGE company; they do not care about thermostats. Maybe Supco will, but I am done wasting my time with it. ... show more

    • Need an answer to a question
When I had my installed to replace a similar model the technician says that yes that is how this thermostat operates. For example if you set it to 76 it'll cut off when it reaches 74 and it won't cut back on until it reaches 78. It's even worse if you haven't older AC unit that doesn't cool as well. I definitely would not recommend this knowing that. Why they built it this way is behind me. Thankfully I now have a all new AC system in a different thermostat entirely. ... show more
