Large Digital Display Electronic Non-Programmable Thermostat, Save Energy Button, Battery Or System Powered, On Screen Low Battery Indicator, For Use With Most 24V Heating & A/C Systems, Millivolt Systems Wall Furnace & Gas Fireplaces, 2 Wire Heat Only & 1 Stage Heat/1 Stage Cool Heat Pumps.
Instructions are transliterated (note not translated) from some other language. Since it is made in China, my guess is the instructions started out in Mandarin. I installed it. I managed to set both heat/cool temperatures to test each cycle on my existing HVAC system. It broke that afternoon. No amount of dropping the cool temperature setting would trigger the A/C. After reinstalling the stock Honeywell unit, the A/C fired up, the moment I switched the furnace back on. Lux's technical support is an answering machine, with a promise to call back in 4 hours. It has been 24 since I made the store eat their returned unit, and they still don't know I am no longer in need of support. Because they did not call back as promised!!!!! This company should be going the way of Mr. Madoff.
