How to choose
Match the schedule to your week
A 5-2 day thermostat uses one program for weekdays and another for the weekend, which is what the LUX PSP511LC, the Honeywell Home X2P and the White Rodgers P150 offer, with the LUX adding up to 4 periods per day. The Coiiwsei uses 7-day, 5/1/1 programming for a different program on each part of the week. The Riseem is non-programmable, so it holds one temperature setting without a schedule.
Check system compatibility first
Compatibility decides the pick more than any other spec. The Coiiwsei suits single-stage or multi-stage systems with 2 heat and 2 cool stages. The Riseem suits single-stage heating and cooling, gas, oil or electric furnaces and cooling-only systems. Check your system type against the pick before buying.
Compare controls, display and power
Controls differ across this group. The LUX PSP511LC and the White Rodgers P150 use button controls, while the Honeywell Home X2P and the Riseem use touchpad controls. The LUX, Honeywell Home and Coiiwsei picks have backlight or backlit displays that stay easy to read. The Honeywell Home X2P works without a C-wire, and the Riseem needs no C-wire on most systems, except heat-only and cool-only systems, while the LUX runs on 2 AA batteries that are included.
