Determine the time periods and heating and cooling temperatures for your weekday pro- gram. You must program 4 periods for each day (MOR, DAY, EVE, and NHT). However, you may use the same heating and cooling tempera- tures for consecutive time periods. You can choose start times, heating temperatures, and cooling temperatures independently for both weekday and weekend programs (for example, you may select 5:00 AM and 70° as the weekday MOR heating start time and temperature, and choose 7:00 AM and 76° as the weekday MOR cooling start time and temperature). Use the following table to plan your program time peri- ods, and the temperatures you want during each period. You may also want to look at the sample program table to get an idea of how the thermo- stat can be programmed.

ENTERING YOUR PROGRAM

We recommend that you remove the thermostat from the wall for programming (especially for entering cooling programming). Fresh "AA" Energizer® alkaline batteries must be installed to perform off-wall programming. BE SURE

SYSTEM SWITCH IS SET TO OFF POSITION BEFORE REATTACHING THERMOSTAT TO SUBBASE!

You cannot program the thermostat with the SYSTEM SWITCH in the AUTO position.
