Step 4: Program Thermostat
After the batteries are installed, the thermostat
can be easily programmed in your hand, before

These periods can be seen individually on the
display as you press the SET SCHEDULE key.

include extra lead time, depending on the
outside temperature and your furnace response
time, to give the furnace a head start to heat the
house before you get up. (This will be a higher
temperature during heating season, or a lower
temperature during cooling season.)
LEAVE 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 tem-
perature during heating season, or a higher
temperature during cooling season.)
RETURN is the time period you want the
house at a comfortable temperature for
activities before bedtime. When deciding what
time to set for your RETURN period, include
extra lead time, depending on the outside
temperature and your furnace response time,
