Answer: 
A single AAA battery (not included) is needed to operate the lighted display however the thermostat will still operate at the desired setting (if the battery is dead) using the 4 wires as referenced in the question. The battery is not needed to hold the setting in the event of a power outage (according to the instructions).

Answer: 
Hi Bean,
This thermostat requires batteries as it is a programmable electronic thermostat, unlike a mercury thermostat which is a non-programmable mechanical thermostat.
The batteries power the thermostat and allow it to maintain the programed settings in its memory.
Mike,

Answer: 
No. You really don't need a clock. It doesn't care what day or time of day it is. It's just a great AUTO heat or cool. Mine is set at 71 and 78. Which works out perfectly here in Florida.

I have a four wire system, the current old thermostat has to be manually switched between heat/cool. Will this one just do it automatically to keep the desired temp? or do I need to get the lesser model that has the manual switch?

Answer: 
Yes. There has to be a three degree difference between heating and cooling. It will even enforce that for you. If you move one to less than 3 degrees separation it will automatically move the other one far enough away.

Answer: 
The system will use two (2) fuse breakers next to each other and will be ganged together by a metal clip if it is using 220 volts. The box label should be marked as such.

Hey Donna,
You'd first need to see if you have a fuse panel or a circuit breaker panel.
If it is a fuse or breaker, you'll need to safely trace the wires leading to the panel from the heaters.
Depending on what type of fuse panel you have will determine what type to look for. Most breaker panels have a double pole for 220V devices, and a single pole for 110V.

The additional information you need to view is also the correct number of amps listed on the fuse/breaker.
Inspect the panel only after turning off the power to the heaters, if you are aware of where they are. If you don't, then make sure the entire is turned off at the main power/disconnect.
As with anything electrical, if you have any further questions or concerns, please consult a local licensed electrician who can answer them in more detail for you.

CUSTOMER REVIEWS

Rated 4.7 out of 5 by 97 reviewers.
Rated 4.0 out of 5.0 by Simple solution. Just what we were looking for. Didn't want all the technology just basic Heat or Cool and set the temperature for our comfort. Simple. June 16, 2016
Rated 4.0 out of 5.0 by ALMOST what I expected. Simple to hook up. Seems to work just fine...as advertised. The only thing I would suggest for this thermostat is (1) A larger viewing window and (2) larger numbers and letters to go with it. Depending on whether there happens to be a glare or not, the readouts are a little hard to see. Overall, I am satisfied. It is what I wanted and so far there have been no problems. May 24, 2016
Rated 4.0 out of 5.0 by Easy to install, easy to use. The main reason I purchased a new thermostat was to get ride of the programmable one we had. The reason I picked this particular one is because of the large easy to read display. It is easy to read to change the temperature, the numbers are huge. The only problem I had was that the words for the "cool", "heat" and "off" are written so small you can't read them. This is why I gave 4 stars instead of 5. The back-light is brighter than I expected, when you push one of the buttons it lights up bright and the contrast is great so you can see it real easy, better than I expected. Push the up button and the temp goes up, push the down and it goes down, easy. March 15, 2016
Rated 3.0 out of 5.0 by Deluxe non programable thermostat the thermostat has a pale green light & the numbers are also very pale. I have trouble seeing the digital reading unless the light in the room is bright. April 26, 2016
Rated 5.0 out of 5.0 by Simple and attractive I bought this because someone recommended a newer thermostat helped with energy efficiency. It was not in stock, but I requested an email to let me know when it was in inventory. It took a couple of days delay to get to me, but I had not scheduled anyone to install it, so other than wanting to see what I bought, the slight delay was of no importance. Once received, I had it on hand but did nothing to install. Then one cold day (17 degrees), I woke up to a VERY COLD house. My thermostat was blank and the "low battery" message was on. I replaced the batteries to no effect. Once the repairman was here, he told me my thermostat was broken and he installed the new one. Heat came on. I was happy that I had the new product in hand. Happy to time it just right! January 20, 2016
Rated 5.0 out of 5.0 by Accuracy Whatever temperture you set it at is the temperture it goes off at. February 23, 2016
Rated 5.0 out of 5.0 by Met my need This product had all the features that I was looking for. Easy to read,easy to set, the back lighting made this possible.
