STEP 4 Program The Thermostat After the batteries are installed, the thermostat can be easily programmed in your hand before it is installed on the wall. If you would prefer to program the thermostat after it is installed on the wall, skip to page 16, and return later to this programming section. The following personal programming chart (pages 11 and 12) may be helpful when planning your program schedule of time and temperature settings for various times of the day. Four time periods are available-MORNING, DAYTIME, EVENING and NIGHT. Each period has its own setting key. MORNING is the time period you want the house at a comfortable temperature when you get up and while you get ready for 9 work or school. (This will be a higher temperature during heating season, or a lower temperature during cooling season.) DAYTIME is the time period you can set for an energy-saving temperature while you are away at work or school. (This will be a lower temperature during heating season, or a higher temperature during cooling season.) EVENING is the time period you want the house at a comfortable temperature for activities before bedtime. (Again, higher heat or lower cool.) NIGHT is the time period you can set for an energy-saving temperature while you are sleeping. (Again, lower heat or higher cool. Although for more comfortable sleeping, some people choose not to raise the cool temperature during the night.) 69-0733-3 You will set one schedule for weekdays, one for Saturday, and another for Sunday, because your requirements will probably be different for each. Fill in the times and temperatures you desire for weekdays, Saturday, Sunday. The factory-preprogrammed time and temperature settings are shown in parentheses. If you decide not to program the thermostat, it automatically controls to these settings. The thermostat requires a time and temperature program for the MORNING period. You can program DAYTIME and EVENING, or leave them blank. You can also change NIGHT or cancel it (see page 15), as you please. Before programming, remove the clear plastic overlay covering the display. When pressing the keys, use the ball of your finger or a soft pencil eraser. Use of sharp fingernails or pencil points can damage the keypad. If at any time during programming you make an error, just press the RUN PROGRAM key, and continue again at the step where you left off. PROGRAMMING 10 69-0733-3
