Comments about LuxPro PSP721U Universal Programmable Thermostat:

replaced my old Honeywell with this unit because Consumer Reports recommended it. Doesn't show the current setpoint readily, the display is too small and hard to read, and the vacation/special setting took me over half an hour to get right. Ok maybe I'm a dummy but the Honeywell was MUCH easier. Wish it hadn't broke on me!

    Comments about LuxPro PSP721U Universal Programmable Thermostat:

    This is a great thermostat ... one of the few that allows you to set the range around the selected temperature to slow down the on/off cycling. I set mine at 68F plus or minus 1F so the furnace comes on at 67F and goes off at 69F. It is just what I wanted.
