You can program the HP2110 5+1+1 days, using the Speed Dial to make it quick and easy. There are four periods for each day where you can set the temperature differently, so that you can have it cool in the afternoon and warm at night. The cycle rate is adjustable, so that you can alter the settings as you need over time. The programming steps are laid out on the LCD display, so that you can always check what the programming is. Like many Lux programmable thermostats, the HP2110 is Energy Star approved, and comes with a pre-programmed heating and cooling schedule that will cut down on your carbon footprint and save you money on energy bills, should you choose to use it.
