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.
