INTRODUCTION
Carrier thermostats are wall-mounted, low-voltage thermostats
which maintain room temperature by controlling the operation of
a heating and air conditioning system. Separate heating and
cooling setpoints, plus auto changeover provide maximum comfort
and flexibility. Batteries are not required; temperature and mode
settings are preserved with the power off.
INSTALLATION CONSIDERATIONS
Power
Note that all thermostat models require no batteries and are not
power stealing. They do require 24vac (both R and C terminals)
to be connected for proper operation. Thermostat will not operate
without these 2 connections.
Models
There are 3 different models. The 9th and 10th letters of the part
number indicate the model. These 2 letters also appear on the
package and on the circuit board. Be sure to have the proper
thermostat for the intended application. Models are:
AC Ð 1-stage cool, 1-stage heat for AC systems only.
HP Ð 1-stage cool, 2-stage heat for either HP, or AC with 2-stage
heat.
2S Ð 2-stage cool, 2-stage heat for 2-speed AC systems, or
2-stage cool, 3-stage heat for 2-speed HP systems.
Use each only for its intended purpose. See Table 1.
INSTALLATION
Step 1ÐThermostat Location
Thermostat should be mounted:
· Approximately 5 ft (1.5m) from floor.
· Close to or in a frequently used room, preferably on an inside
partitioning wall.
· On a section of wall without pipes or duct work.Thermostat should NOT be mounted:
· Close to a window, on an outside wall, or next to a door leading
to the outside.
· Exposed to direct light and heat from a lamp, sun, fireplace, or
other temperature-radiating object which may cause a false
reading.
· Close to or in direct airflow from supply registers and return-air
grilles.
· In areas with poor air circulation, such as behind a door or in
an alcove.
Step 2ÐSelect Model and Jumper
AC Model(1-stage cool, 1-stage heat) is to be used for single-
stage heating and/or cooling applications only. It CANNOT be
used with optional outdoor temperature sensor. (See Table 1 and
Fig. 2, 3, 4, 14, and 19.)
HP Model(1-stage cool, 2-stage heat) can be used with a
single-speed heat pump (HP), or an air conditioner (AC) with a
2-stage furnace or fan coil. A resistor (R19) serves as a HP/AC
selector jumper. This thermostat comes configured from the
factory as a heat pump thermostat. Leave R19 installed for HP
operation. Cut and discard for AC operation. When AC operation
is selected, the O/W2 terminal is converted from a reversing valve
output (O) to a second-stage heat output (W2). This output can be
used to control 2-stage furnaces or 2-stage electric heat in fan coils.
(See Table 1 and Fig. 5, 6, 7, 15, 17, and 21.)
2S Modelis for 2-speed compressor HP and AC systems only.
Output Y1 controls compressor low speed and output Y/Y2
controls compressor high speed. Jumper resistor R19 serves as
HP/AC selector exactly as described above for HP model. (See
Table 1 and Fig. 8 through 13, 16, and 18.)

							Step 3ÐInstall Thermostat
Before installing thermostat, turn off all power to unit. There
may be more than 1 power disconnect. Electrical shock can
cause personal injury or death.
1. Turn OFF all power to unit.
2. If an existing thermostat is being replaced:
a. Remove existing thermostat from wall.
b. Disconnect wires from existing thermostat, 1 at a time. Be
careful not to allow wires to fall back into the wall.
c. As each wire is disconnected, record wire color and
terminal marking.
d. Discard or recycle old thermostat.
NOTE:Mercury is a hazardous waste and MUST be disposed of
properly.
3. Open thermostat rear door (mounting base) to expose mount-
ing holes. The base can be removed to simplify mounting.
Snap apart carefully at hinge to separate mounting base from
remainder of thermostat.
4. Route thermostat wires through large hole in mounting base.
Level mounting base against wall (for aesthetic value
onlyÐthermostat need not be leveled for proper operation)
and mark wall through 2 mounting holes.
5. Drill two 3/16-in. mounting holes in wall where marked.
6. Secure mounting base to wall with 2 anchors and screws
provided, (additional anchoring holes available for more
secure mounting if needed) making sure all wires extend
through hole in mounting base.
7. Adjust length and routing of each wire to reach proper
terminal and connector block on mounting base with 1/4 in. of
extra wire. Strip only 1/4 in. of insulation from each wire to
prevent adjacent wires from shorting together when con-
nected.
8. Match and connect equipment wires to proper terminals of the
connector blocks. (See Table 1 and Fig. 2 through 24.) Both R
and C must be connected for proper thermostat operation.
Improper wiring or installation may damage the thermostat.
Check to make sure wiring is correct before proceeding with
installation or turning on unit.
9. Push any excess wire into wall and against mounting base.
Seal hole in wall to prevent air leaks. Leaks can affect
operation.
10. Snap hinge back together.
11. Close thermostat assembly making sure pins on back of circuit
board align with sockets in connector.12. Turn ON power to unit.
On power up, LCD readout will display AC, HP, A2, or H2
depending on the thermostat model and jumper status. See Power
On Check under Operational Information on page 11 for
explanation.
Step 4ÐSet Thermostat Configuration
Configuration options, like the R19 configuration jumper are
intended to be selected at installation and are normally not
modified by the homeowner. These options are not discussed in the
Homeowners Guide and therefore must be made as part of the
installation. A special procedure allows entry into the configura-
tion mode. The thermostat will automatically exit this mode if no
button is pressed for 3 minutes. While in the configuration mode,
up to 8 option choices can be made:
Option 01:Anticipator adjustment
Option 02: Clean filter timer adjustment
Option 03: Fahrenheit or Celsius operation
Option 04: Enable fan (G) on with any heat (W)
Option 07: Enable zoning
Option 08: Auxiliary heat lockout temperature adjustment
Option 13: Room temperature offset adjustment
Option 15: Enable AUTO mode
An explanation for each of these and how to enter the configura-
tion mode follows.
To enter the configuration mode:
Press and hold the FAN button for approximately 10 sec until
room temperature disappears and display reads 01. You are now
in the configuration mode.
NOTE:If the FAN button is pressed again or if no button is
pressed for 3 min, the thermostat will exit the configuration mode
and return to normal operation. To re-enter the configuration
mode, the FAN button must be pressed and held for 10 sec again.
While in configuration mode:
The display is used to show both the option number and the
selection choice within that option.
OPTION 1ÐANTICIPATOR ADJUSTMENT
This adjustment controls the sensitivity and cycle rate of the
thermostat. Higher numbers decrease the sensitivity and slow the
cycle rate. Lower numbers increase sensitivity and increase cycle
rate. However, a limiting feature will not allow more than 4
equipment cycles per hr, regardless of setting. Values can range
from 1 to 9. Factory default setting is 3. This default selection will
provide optimum performance in nearly all installations. Try it
first. Do not change setting unless there is evidence of need to do
so.
Unlike conventional anticipators, this setting is not to be deter-
mined by current draw. There is no need to measure, know, or

OPTION 13ÐROOM TEMPERATURE OFFSET
This option allows calibration (or deliberate miscalibration) of
room temperature sensor. There are various reasons why the
homeowner may want to have displayed temperature adjusted to a
3 
						

							higher or lower value. The selected number is the number of
degrees, plus or minus, which will be added to the actual
temperature. The number can range between -5 and +5. Factory
default is 0. This adjusted value will be used as actual temperature
for both display and control action. For example, if 2 is selected,
72ÉF actual will read 74ÉF. If set point is 72, the room will control
to an actual value of 70 which will be displayed and acted upon as
if it were 72. The effect is that a positive number selection will
make the room temperature lower and vice versa. This thermostat
is factory calibrated within an accurancy of plus or minus 1ÉF, so
this adjustment will provide the best accuracy when set to 0.

Step 5ÐCheck Thermostat Operation
FAN OPERATION
1. Press FAN button, starting fan operation. FAN icon turns on.2. Press FAN button again, stopping fan operation. FAN icon
turns off. (Some fan coils have 90 sec fan off delay, so fan
may not stop immediately.)
HEATING OPERATION
1. Press and release MODE button until HEAT icon appears.
This selects heating mode.
2. Press and release up button until set point is at least 5É above
room temperature. Within a few seconds, HEAT ON icon will
either stay on or flash. Flashing indicates a heat demand exists,
but the cycle timer or timeguard timer is delaying heat turn on.
(See Operational Information on page 11 for timer explana-
tion.) To defeat timer, simultaneously press FAN and up
buttons. Heating will come on within a few seconds and
HEAT ON icon will stay on. Lowering set point to below
room temperature will turn off heating and remove HEAT ON
icon within a few seconds.
COOLING OPERATION
1. Press and release MODE button until COOL icon appears.
This selects cooling mode.
2. Press and release down button until set point is at least 5É
below room temperature. Within a few seconds, COOL ON
icon will either stay on or flash. Flashing indicates a cooling
demand exists, but cycle timer or timeguard timer is delaying
cooling turn on. (See Operational Information on page 11
for timer explanation.) To defeat timer, simultaneously press
FAN and up buttons. Cooling will come on within a few
seconds and COOL ON icon will stay on. Raising set point to
above room temperature will turn off cooling and remove
COOL ON icon within a few seconds.
OUTDOOR TEMPERATURE
If system is equipped with an outdoor temperature sensor, check its
operation by pressing the up and down buttons together. Outdoor
temperature will be displayed for about 5 sec. If -- is displayed,
the outdoor temperature sensor is absent or not properly connected.
Step 6ÐChecklist
