Programming Thermostat Schedules —

fore programming the thermostat, plan the thermostat daily
schedule. The schedule is divided into 7 days (Monday through
Sunday). Each day can have 2 (Occupied 1, Unoccupied),
3 (Occupied 1, Occupied 2, Unoccupied), or 4 (Occupied 1,
Occupied 2, Occupied 3, Unoccupied) time periods. Each
occupied time period has a start time, stop time, heating set
point and a cooling set point. The unoccupied time period
has a heating set point and a cooling set point. The unoc-
cupied time period is active whenever an occupied time
period is not active. Fill in Table 1 below as an aid to pro-
