SAFETY CONSIDERATIONS
Read and follow manufacturer instructions carefully. Fol-
low all local electrical codes during installation. All wiring
must conform to local and national electrical codes. Improper
wiring or installation may damage thermostat.
Recognize safety information. This is the safety alert sym-
bol . When the safety alert symbol is present on equipment
or in the instruction manual, be alert to the potential for person-
al injury.
Understand the signal words DANGER, WARNING, and
CAUTION. These words are used with the safety alert symbol.
DANGER identifies the most serious hazards which will result
in severe personal injury or death. WARNING signifies a haz-
ard which could result in personal injury or death. CAUTION
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Commercial Thermostat
is used to identify unsafe practices which would result in minor
personal injury or property damage.
GENERAL
Carrier's 7-day, commercial, programmable thermostats are
wall-mounted, low-voltage thermostats which maintain room
temperature by controlling the operation of an HVAC (heating,
cooling and ventilation) system. Separate heating and cooling
set points and auto-changeover capability allow occupied and
unoccupied programming for energy savings.
All thermostats allow up to 4 time/temperature settings to
be programmed per 24-hr period. Each thermostat stores pro-
grams for 7 independent days. Batteries are not required. Dur-
ing power interruption the internal memory stores comfort
schedules for an unlimited time while the clock continues to
run for at least 72 hours.
The thermostat can be configured to accept several different
equipment configurations, from single-stage heating and cool-
ing to 3 stages of heating (heat pump only) and 2 stages of
cooling. The thermostat comes factory configured for air con-
ditioner operation.
INSTALLATION
Step 1 — Thermostat Location —
should be mounted:
• approximately 5 ft from the floor
• close to or in a frequently used room, preferably on an
inside partitioning wall
• on a section of wall without pipes or ductwork
• where temperature operating limits are within 41 to
104 F (5 to 40 C)
• where humidity operating range is within 0 to 95% rela-
tive humidity, non-condensing
The thermostat should not be mounted:
• close to a window, on an outside wall, or next to a door
leading to the outside
• where exposed to direct light and heat from a lamp, the
sun, a fireplace, or any other temperature-radiating
object which may cause a false reading
• close to or in direct airflow from supply registers or
return air grilles
• in areas with poor air circulation (such as behind a door
or in an alcove)
Step 2 — Set DIP Switches —
(Dual In-line Package) switches on the back of the circuit
board which must be configured by the installer. The ON posi-
tion is indicated by small letters on the switch. Ignore the num-
bers (1-4) on the switch. The switch designation (A-D) is print-
ed on the circuit board above the switch. To change a switch
position, use the corner of a small screwdriver to slide the
switch ON or OFF. Set the DIP switches before installing the
thermostat.
