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.
