Controlled Heat Well
Fairly easy to program
No Override Time Control
We bought and installed this best-buy thermostat, and it works well; has a large clear display; and was easy to program with its Copy operation; and has a very good price. But it has one big design flaw: when you override the temperature setting, there is no way to give or change the time that the override runs. If you boost the heat setting by 2 degrees, say, the override will be in effect until the next program change time, whether that's in 15 minutes or 15 hours -- there's no other choice. So to boost the setting by 2 degrees for 90 minutes, say, you have to set a kitchen timer for your 90 minutes, and then return to the t'stat to cancel the override manually. <br /><br />This is a great step backward from the 10-year-old Honeywell RTH8000 that we are replacing. When you override the setting on that unit, it immediately presents a clock time setting for how long to override before reverting to the program. You set the time for it to run right then, and forget it.<br /><br />The lack of this common-sense feature in the Lux unit is, to me, a great inconvenience. To my wife, it is a deal-breaker. So we will be discarding the Lux unit and replacing it, probably with the Honeywell RTH8500D. The Honeywell units seem to be the only ones that get this commonly-used feature right. A great shame.<br /><br />I would recommend this to a friend, but only with the caveat that they must be willing to live with the flawed override function.
How long have you owned it:
More than six months
Yes, I would recommend this to a friend.
