PROGRAMMING
The keyboard is located behind the thermostat cover with
three frequently used keys by the display. The thermostat
display shows day, time, program period, temperature, system
and fan operation selection.
The thermostat can be set for four times and up to eight
temperatures for each day of the week (28 independent time
and 56 temperature settings). The ▲▲ and ▼▼ keys provide
quick temporary temperature changes to increase comfort.
The Hold Temp key provides energy efficient operation for
extended periods of time.
Before starting the programming procedure, use Table 9 to
organize the program schedule. The factory preprogrammed
time, temperature and fan settings are shown in brackets. If a
daytime energy savings period is not used, press the period
key (Leave or Return) until the time is blank. The fan setting
feature is available on select thermostat models.
