Question: can it be used for straight cool ac also
Document: Easy to install. Good directions. Works great. Using to control heat in my observatory and the low set point of 41F is great for when the space isn't being used.
Easy to install. Works much better than older style thermostats. Rooms stay much more even temp. Good looking unit also
This was to replace a thermometer that was &#34;iffy&#34; meaning that sometimes it would stick either off or on causing the room to overhear or be too cool.. It is hard to find thermostats for resistant heating that show the temperature and look nice and this fills the bill for me. So-far it is working well and that is the main thing I want.RSW
I bought this thermostat after previous good experience with the same model. It is simple to install, accurate, and easy to use. I like the way it steps down the heat produced by the attached heater(s) as it approaches the set temperature. That seems to make it hold the set temperature very smoothly, one never notices that the heat is going on and off. The down side of that feature is that it cannot be used to control a heater which has a fan.
I can't say that this will happen in every house with this type of room configuration, just that it happens in mine.Also, I need to retract my original statement about programmable thermostats. I originally saw no value in turning the thermostats down, especially during the day, but I failed to consider the drop in outside temperature during the night.
They were too slow to respond and didn't keep the room temperature stable, thus using more electricity than was really needed. I'm disabled and don't work anymore so fiddling with programs doesn't make sense. Besides, I know from experience that all the energy saved when allowing a room to cool for a few hours is needed to stabilize the temperature of that room once it's being heated again so why not just keep a constant temperature.
(November) The old thermostat must've had a temp swing of about +/-6 degrees of the set temp. So I wanted about 72 I'd get anywhere from 66 to 78. Way to much of a shift to be comfortable and also the POWER BILLS!!! This hopefully will cut that down and I hope it is really a true .5+/- of the set temp like it says.
Wired exactly according to the simple 4-wire diagram, white to white and black to black. Also, set up a fan during operation to prevent convection currents from effecting the thermostat's room temp measurement. Same problem occurred. Called Honeywell, the &#34;technician&#34; was totally unfamiliar with electricity, home circuits, heating systems, and this product. Whew, if electricity was so simple anyone could handle tech support.
Circuit board looks an old design as to change from C to F uses switch on circuit board + several plugs for connecting front unit with base unit which could have connection problem years later. It works but the temperatures reading does not show accurately; ex, it shows 59 degrees while other three temperature gauges, used for testing, show 61. I tested for two days long and it always  shows 2 degrees lower than other devices.
For some reason these thermostats will not achieve a proper balance in this situation. One will always wind up driving its heater far too much while the other ends up rarely providing heat. I've tried switching them around but the problem doesn't follow a particular unit, nor does it occur always in one specific room. These thermostats also get very warm when running the heaters at 100% for an extended time. This is on the side opposite the temperature sensor but I suspect it may effect the reading.
Answer: no
