 keys change the temperature. The 

thermostat displays day, time, program period, temperature and system settings.

There is an individual key for each of the four program periods:

—The program period when you want the house at a comfortable temperature when you get up and while you 

get ready for work or school. (This is a higher temperature during the heating season and a lower 
temperature during the cooling season).

—The program period you can set for an energy-saving temperature while you are away at work or school. 

(This is a lower temperature during the heating season and a higher temperature during the cooling 
season).

—The program period when you want the house at a comfortable temperature for activities before bedtime. 

(This is a higher temperature during the heating season and a lower temperature during the cooling 
season).

—The program period you can set for an energy-saving temperature while you are sleeping. (This is a lower 

temperature during the heating season and a higher temperature during the cooling season).

Table 3 can be helpful when planning your schedule for time and temperature settings. The thermostat 
preprogrammed settings are shown in parentheses (  ).
