Question: Can it be set to 40 or 42 degrees ,to keep above freezing, and left that way?
Document: (3) The adjustable delay for the unit to recycle (turn off-on).I love my hot water heat, but it takes several minutes to start heating from a cold start, so I set the thermostat to the minimum setting. With a gas hot air system or when using the A/C the unit might recycle to often at this setting. So far this thermostat seems to keep my house temperature within a couple of degrees at all times, and has performed flawlessly while in the Heat mode.
I just got my most recent power bill - another drop in costs! Ok, so from July to August (generally getting hotter) my power consumption dropped from 1214 Kwh to 721 Kwh (more than a 40% reduction) - then, from August to September (on average 7 degrees cooler) it dropped from 721 Kwh to 490 Kwh (more than a 32% reduction).
The product itself is a little overly complicated to use, but I suspect that programmable thermostats in general are in effective. The recommended EnergyStar/default program that will save you all kinds of money is comprised of outrageous temperature settings that just will not work (85 degrees is way too hot inside). This device may have some use for somebody, but I returned it.
I have decided to just buy a simple (non-programmable) unit that I can set to the temperature I want and keep it there!! !
Bought 2 of them about 8 years ago to replace manual Honeywells.Dial switch (big round thing on the left) stopped working properly after 2 years - just doesn't fix itself in a proper position. On both units!Since there is no daylight time adjustment button (or something like that), twice a year a have a pleasant task of trying to set dial switch in a position where it would allow me to set time.
Easy to install and programming the temperature and time is very simple. temporary adjustment of the temperature is simple as well and will revert back to the programmed settings at the next scheduled time unless you set it on Hold which will keep it at the specified temperature until you decide to unhold it.
We have had our thermostat up for a while now. I think it has helped our electric bill a tad, but I know it is way easier to see and set than our old one, I also love the fact that I can set my own temps for different times. When it comes time for another, would for sure get another one.
We've owned this product now for a little over a year. It is completely out of whack when it comes to regulating temperature. I've set all the numbers to keep the house at 68. We live in a very cold area. I have checked the swing (1 degree), recallbrated it, reset it, re-programmed it, and the heat comes on whenever it feels like coming on, and it's not often.
This thing is missing 2 major features that drives me nuts. First, it doesn't show the Set temperature on the display all the time, just the current room temperature. I have to press one of the up or down buttons to see where my temp setting is at. Second, when it is in override mode, there is no easy way to get back to Run Schedule. These are big problems for me.
I selected the LUX 1500E thermostat because it was one of the top rated by Consumer reports, and very affordable. I received it within a few days and it was easy to install..instructions were clear, and the programming is simple. My house is actually warmer because I can set my heat to come on when we are home and need it and keep the heat off when we are not home. That helps my heating bill since I have a big, old home. I recommend it highly! !
