Program the Thermostat
OVERVIEW
The keyboard is located behind the thermostat flip-up
cover. See Fig. 18. There are 16 keys to set, review and
modify programmed times and temperatures. The liquid
crystal display (LCD) shows day, time or temperature and
which programming period is operating.
The thermostat can be set for two occupied and two
unoccupied time and temperatures for each day of the week
(28 independent settings). The two override keys provide
quick temporary programming changes for increased occu-
pant comfort.
IMPORTANT: To program the thermostat, 24 Vac is re-
quired (turn on system power) and the keyboard lock-
out switch (see Fig. 27) must be in the ON-KEYBD
position.
