Answer: 
The word "HEAT" flashes when the furnace is running. When the furnace stops running it will still say "HEAT" but it will NOT flash.

Answer: 
Sharon, the word heat will flash when the thermostat calls for the furnace to run. HEAT will flash until the room temperature exceeds the Set temperature, then flashing will stop and the heating unit will be off. This will be the same operation for cooling.

5-2 Day Universal Application Programmable Thermostat is rated 4.1 out of 5 by 23.
Rated 2 out of 5 by from Loved it until it died after only 2 yrs Pro- It has two settings that most other brands don't hav. 1) countdown delay that lets you set a certain temp for X hours or days before resuming the normal programmed setting. 2) swing setting is adjustable so you can set the temp variance greater before the AC/Heat comes on to reduce the freq off on/off cycles Cons- Lasted only 2 year before the display says LO despite new batteries being used

It worked well for a while then it won't allow me to "program" it anymore. The batteries were new & had juice so it wasn't that. I like the concept of programmable thermostat BUT I SHOULD BE ABLE TO PROGRAM & RE-PROGRAM IT WHEN I WANT.

Rated 5 out of 5 by from Lux is a quality product I previously had two Lux programmable thermostats for my heating and air conditioning units. So it was pretty easy to make the upgrade. The old ones were fourteen years old and one of them starting having some glitches so I replaced them both with these new ones which have better features, One of them being that they become illuminated when you touch one of the buttons and the characters are bigger and easier to read. They give you the tabs to label the wires-this is most important when installing. Programming is very simple. I am very satisfied with these thermostats.

Very easy install on my two wire low voltage heating system. The secondary programming for delay and swing state had to be done fairly quickly but can be re-entered if necessary. Overall an excellent and reasonably priced product. Just wish they were carried in the store.

Rated 3 out of 5 by from Is OK for the price The front cover is a little flimsy. Simple controls. Seems accurate.

Rated 4 out of 5 by from replacement thermostat at home This Lux thermostat provided an important feature that many other more expensive thermostats do not have. That is an easily adjustable swing value. This allows for fewer on/off cycles and thereby increased efficiency of the gas heat, without degrading the comfort level. It can be finely tuned to your house.

Rated 5 out of 5 by from All the Right Features at a Great Price I have the latest model Lux TX500Uc with Temperature Swing Control. This control lets you precisely set the +/- temperature range for thermostat operation in different (1-9) increments of 0.25F from +/- 0.25F to +/- 2.25F. For example, if you set the "target" temperature to 70F, the temperature range can be set anywhere between these MIN/ MAX temperatures in 0.25F increments: (1) Heat ON at 69.75 and heat OFF at 70.25 = very precise control with frequent heater cycling on/off. (9) Heat ON at 67.75 and heat OFF at 72.25 = large temperature swing with less heater on/off. (I set my temp to 70F and the swing to 6 (0.25F X 6 = +/- 1.5F, equals ON at 68.5F and OFF at 71.5F) Most furnaces are more efficient (use less $$) with fewer on/off cycles due to energy being "wasted" heating the plenum (air chamber) before the blower motor starts running. Likewise, in the summer months, less on/off cycling of the AC compressor is more cost effective and saves wear and tear on the compressor motor. Enough of the "technical stuff"! The Lux displays the SET temperature and the actual ROOM temperature, the day of the week, the time, and a bar indicating battery life. It is easy to program with 4 time periods per day (Morning, Day, Evening, Night) or just 2 (Day, Night). You can program in a number of days for filter life and the word "FILTER" will flash when the filter should be changed. For a temporary change in temperature setting (until the daily time period changes), just press the up/down arrows. For a "permanent" setting change, press the "HOLD" button after the arrows, and the set temperature will be held until you press "HOLD" again; this is a very easy way to set the temperature when going on vacation. Again ... all the right features at a great price!

Rated 5 out of 5 by from Nice Thermostat The thermostat is easy to use and program. We like the fact that it displays BOTH the set temperature AND the current inside temperature. Many of the ones on the market do not!!
