Question: What happens if the batteries die, will the heat not turn on?
Document: Attach to the wall, put battery in, cover, and viola... thermostat that works.The only thing I don't like about this is that it's very sensitive. A change of 2 degrees will make this thing turn on! Very annoying, because alot of times, the stove will be cycling down, and then start right back up again. Why not just let the thing run :(  You can fix that by just bumping the heat up so it keeps it on, and then back down.
It gets hotter when I turn the temp up, and colder when I turn the temp down. You can't ask for much more in a thermostat.
Worked fine for a year, accuracy began to dwindle(fresh batteries every 6 months), then thermometer quit. Switches are  flimsy like a child's toy.
Using on pellet stove. Functionally, it works like it should,  The backing doesn't hold the wiring block when trying to separate unit to get at the batteries. That part could be better designed.
Least expensive digital thermostat. Easy to use. Simple to install. It took less time to install than to get the few tools and two AAA batteries. These replaced analog/ mercury switches on electric heaters.
The thermostat was off and my heater was running indefinitely. So I had to kick the breaker to power down the heater and took a look at the thermostat. The batteries that came with it have gone corrosive.That really shouldn't happen this quickly; I'm going to replace the batteries and see how it goes from here.
met my expectations. Use it for heat only in my garage...two wire made it easy. I recommend for that purpose
We have three heaters that keep our shop and garage warm and we've always used the crummy dial-type controllers with them, but wanted something that would be more accurate. These are extremely easy to install, don't require a power lead (run on batteries), have basic controls that anyone can understand, and look much nicer than the antiquated dial-style.They appear well made, and I am amazed they are so inexpensive.
Works great for Single stage systems where you don't want to mess with programming. Remember, this is NOT for dual stage units or heat pumps. For my Home AC it is easy to set with good tempurature control.
As long as you remember that you bought a non-programmable, basic unit, this should meet your needs.Cons: not a lot, really. Two come to mind, and together are why I docked this a star. First, I have not found a way to power the unit with the same DC power supply that powers the fans I have hooked up to it. It appears to require batteries, though the batteries also appear to have good life due to low draw.
Answer: yes
