Question: can the thermostat be turned off, so both the heater and the a/c will not be turned on, regardless of temperature?
Document: I love having this thermostat. I got a really good deal on the price (&lt;50)...but I think it would be worth it regardless.Installation wasn't complicated. I didn't even know if this would work with my traditional setup - the FAQ was confusing, but it turned out to be a very simple install and worked like a charm.
I too made the mistake of purchasing this unit. It does not perform in the manner I expected. All I wanted was a reliable unit that turned on the heat when it was cold and the a/c when it was too warm. What I received was an extremely complicated piece of electronics. I followed the instructions to no avail. I called customer service and he guided me thru the programming. I am now waiting to ascertain if it will function as desired.
It turned out to be the furnace and not the thermostat. The thermostat works great, keeps an even temperature and you can program it without having it attached to the wall. The programming is step by step, and does not require a degree in engineering to figure out. I know some reviewers did not like the idea of having to touch the screen to light it up, but the touch does not change anything and is not that much of an inconvenience.
The default temperature setting is pretty well for my home. I just keep it as default. All I adjusted is for Weekend (Sat and Sunday). Ever since I install this, I hardly need to turn it on and off OR adjust the temperature constantly.I had a little worry before installing it. But it turned out it's a lot easier than I thought. Before removing the old thermostat, please make sure to turn off the main power of your AC and AC-related switch.
They made it cookbook-like steps. Just don't be intimadated by the codes. They are like measurements in cooking: teaspoons, tablespoons, cups, quarts... and putting in the ingredients at the right time.Now that the new thermostat has been controlling the heater for a few months, it really shows its superiority. It keeps the temperature even. That 84 y/o I mentioned above needs the house very warm. With all the functions programmed by the touchscreen screen, he can't mess with it.
Prior to installation, I recommend you get out the documentation with your heat pump, AC, heater, or whatever and determine which settings you'll need to tweak once you get through the installation of the hardware. This will save you a lot of headaches down the road.After a few days of use, I can say I'm very impressed with the "smarts" of this thermostat. It figures out how long it takes to cool your place and gets it to your desired temperature by the time you specify.
You can set a different program for every single day of the week. Programming the temperature and times is really slick - you can select any day or days of the week and make them the same program. There are four temperature / time settings per day.Now that the thermostat has run for a few weeks, the thermostat has learned how long it takes to arrive at the set temperature and starts up my hot water heater plenty early to get there on time.
It requires a 3 degree separation between Heat and A/C. This may not sound like much, but on days where the temperature swing can vary 25-30 degrees between night and day, it's a noticeable difference. If I have it set to keep the house warm on a cool night (temps in the 50s outside means the thermostat is set on 73 for the Heater), then it'll get hot in the house the following day when temps get up into the 80s.
Its display is lower than normal before and right after ON and higher than normal before and right after OFF. Because of this &#8220;bug&#8221;, my gas heat system, if I am not mistaken, all the gas heating system, are turned off too fast in the temperature maintaining mode. It turns off in about 15 to 20 minutes and the radiators do not get chance to be heated (less than 10% of each radiator only started to get warn) . What a waste!
I bought a few of these thermostat because it says automatic switch from heat to A\c. That is not so !! I am very disappointed and am trying to return them. There is no button to have backlight on.
