Carrier DEBONAIR 33CS Owner's Manual

IMPORTANT: Read entire instructions before program-
ming the thermostat.
GENERAL
The commercial, programmable thermostats are wall-
mounted, low-voltage thermostats which maintain room tem-
perature by controlling the operation of an HVAC (heating,
cooling and ventilation) system. Separate heating and cool-
ing set points and auto-changeover capability allow occu-
pied and unoccupied programming schedules for energy savings.
All thermostats allow up to 3 occupied and one unoccu-
pied time/temperature setting to be programmed per 24-hr
period. Each thermostat stores programs for 3 different days
(Saturday, Sunday, and Monday through Friday). Batteries
are not required. During power interruption the internal
NEVERLOST™ memory stores programs for an unlimited
time.
