Anyone who can read and use a screw-driver can probably install this unit. You mount the back to the wall, hook up the wires to the back plate (Mine uses two), install the batteries and program the unit while on the couch, and then click it on to the base.

The limitation I mention is that you get 2 AM times, and 2 PM times, not 4 whenever times. This works if you go to bed at 10PM. I set ~mine~ so my first AM is turn down after midnight, and my second AM is up at wake-up time. But hen I cant turn the heat down again until lunchtime, the first possible time, at 12:00PM. And Programming is in intervals of 15 minutes only.

It also has a lock feature. If you 'lock it' and lose the instructions, you might get upset like another reviewer did. But it'd be your own fault...

All in all, good for standard purposes.

Terrible

terrible, thermostat is locked, and won't un lock... tempature is stuck at 83 degrees in Houston summer heat, you're better buying a fan and a bucket of ice.

      Comments about ACE HARDWARE Ace® 4 Program Programmable Thermostat:

      I installed it with ease. A very little screw that secures the red wire fell out of my bulky fingers and fell. I never did find it, so I took a screw from one of the contacts I wasn't going to use. After completing installation I wanted to test that the thermostat was indeed delivering the message (millivolt connection) to the wall heater.No such luck. I fussed with the programing to get the heater to fire up (yes, the pilot was on). I gave up for the day and went home. The next day I returned to find that the heater had apparently come on as the room was at a comfortable temperature. Would like to have had a TEST mode.

        Comments about ACE HARDWARE Ace® 4 Program Programmable Thermostat:

        First unit the temp would transfer from 70 to 85 at midnight. The second unit would do the same thing 70 to 85, and the diff. temp was set to close =/- 2deg.causing the ac to short cycle. save your time and money and buy a quality thermostat.

              Comments about ACE HARDWARE Ace® 4 Program Programmable Thermostat:

              This would be the best and most cost effective unit if it were not for one thing - in the Spring or Fall, it cannot be on both heat and cool mode, so if it is 85 degrees during the day and 50 degrees at night, you can't have it cool during the day and heat during the night - it can only be in one mode at a time. This is a major disappointment.

                    We've bought 3 units, and 2 of them went up in smoke within 10 minutes of using. On the working unit the heat/ac switch keeps getting burnt, but it's still usable.

                      The instructions do not cover all the possible wirings of older systems. But with a little experimentation it was easy enough to figure out. Will replace the other thermodstats in the house with the same model.
