Install Accessories - Carrier 33CS Installation, Start-Up, And Operating Instructions Manual

HEAT PUMP CONFIGURATION (Steps 3 and 4) — To set
the thermostat for heat pump operation, Advanced Setup
Step 3 must be configured to ON. Use the UP and DOWN AR-
ROW buttons to configure the step. The default is OFF. Press
the mode button to continue to Step 4. Step 4 is used to set the
reversing valve polarity for the heat pump. The variable can be
set to either "B"or "O." Set the reversing valve polarity to the
correct value depending on the application. The default is "O."
NOTE: Step 4 will appear only if Step 3 is set to ON. Step 5
will appear only if Step 3 is set to OFF.

ELECTRIC HEAT CONFIGURATION (Step 5) — Step 5 is
used to configure the thermostat for first stage electric heat. The
variable can be configured ON or OFF. The default is OFF.
NOTE: Step 5 will appear only if Step 3 is set to OFF.
DEADBAND (Step 6) — The deadband is the difference in
temperature above the cooling set point or below the heating
set point that the thermostat will wait before turning on the first
stage of heating or cooling. For example, if the cooling set
point is 82 F (28 C) and the deadband is 2 degrees, the first
stage of cooling will not be energized until the temperature
reaches 84 F (30 C). The range of values is 1 to 6 degrees. The
default is 2 degrees.
SET POINT MINIMUM DIFFERENCE (Step 7) — The min-
imum difference between heating and cooling set points can be
user-configured. The range is from 0 to 6 degrees. The default
is 2 degrees. The minimum difference is enforced during
Autochangeover and Program On operation.
CYCLES PER HOUR LIMIT (Step 8) — The number of
times that heating or cooling can be energized per hour can be
configured. Set the variable to "d" for no limit. Set the variable
to "d1" to disable the 5-minute compressor lockout. The vari-
able can also be set from 2 to 6 cycles per hour. The default is
6 cycles per hour.
Damage to compressor could result if 5-minute compressor
lockout is disabled or compressor is allowed unlimited
cycles. Do not set thermostat Advanced Setup Step 8 to "d"
or "dl" unless specifically recommended for the application.
PRE-OCCUPANCY PURGE TIMER (Step 9) — The pre-
occupancy purge allows fresh outside air to be brought into the
space before the Occupied 1 time period. The timer limits the
amount of time that the purge can operate. The timer can be set
from 0 to 3 hours with 15-minute intervals. The default is
0 hours (disabled).
BACKLIGHT DISPLAY (Step 10) — The display backlight
can be set to ON (always on) or OFF (turn off 8 seconds after
usage). The default is ON.
ECONOMIZER OUTPUT (Step 11) — The thermostat has
an output terminal which can be controlled during Occupied
periods. This output terminal allows for the control of other de-
vices such as economizers, lighting, water heaters, and base-
board heaters. The output can be set to NO (normally open) or
NC (normally closed). The default is NO.
If the Economizer Output configuration is set to NO, then
the W3/ECO terminal of the thermostat is energized when the
thermostat is in Occupied periods 1, 2 and 3, and also during
Pre-Occupancy Purge. The W3/ECO terminal is deenergized
during Unoccupied periods.
If the Economizer Output configuration is set to NC, then
the W3/ECO terminal of the thermostat is deenergized when
the thermostat is in Occupied periods 1, 2, and 3, and also dur-
ing Pre-Occupancy Purge. The W3/ECO terminal is energized
during Unoccupied periods.
SERVICE FILTER (Steps 12 and 13) — Step 12 allows the
user to reset the Service Filter counter to zero and remove the
1204
"SERVICE FILTER" icon (if displayed on the thermostat
screen). Press the FAN button while in Setup Step 12 and the
counter is reset to zero. Press the Mode button to adjust the
number of hours the blower will run before the "SERVICE
FILTER" icon is displayed. The range is 0 to 1950 hours. Set
the variable to 0 to disable this function. The default is
500 hours.
SOFT START (Step 14) — The soft start is used when multi-
ple units are used in an application. The soft start staggers the
start up times of the units in the event of power loss and restart.
Each unit should be assigned a unit ID number. The 30-second
delay time is multiplied by the unit ID number to get the total
soft start delay time for each unit. For example, if the unit ID
number is 10, set the Soft Start function to 10, the start up delay
time is 30 seconds x 10 = 300 seconds (5 minutes). The range
is 0 to 99 (ID numbers). A value of 0 disables the function. The
default is 0 (ID number).
FAHRENHEIT/CELSIUS OPERATION (Step 15) — The
thermostat can be set to operate in Fahrenheit or Celsius
degrees. Set the variable to "F" for Fahrenheit operation. Set
the variable to "C" for Celsius operation.
SECURITY LEVEL (Steps 16 to 18) — The Security Level
limits the actions that the user can perform at the thermostat.
There are 4 security levels. When the security level is set to
"0," no security will be in effect. When the security level is set
to "1," the set point range is limited by the settings of Steps 17
and 18. When the security level is set to "2," the set point range
is limited by the settings of Steps 17 and 18 and the Program
On thermostat operation mode is always in effect. When the
security level is set to "3," the set point range is limited by the
settings of Steps 17 and 18, the Program On mode is always in
effect, and set point changes are prohibited. The default is 0.
NOTE: The Fan button is ignored when security Levels 2 or 3
are in effect.
Security Maximum Heat Set Point (Step 17) — If the Secu-
rity Level is not set to 0, the maximum heating set point will be
in effect. The user will not be allowed to set the heating set
point over the specified value. The range of values is 35 to 99 F
(1 to 37 C). The default is 80 F (27 C).
Security Minimum Cool Set Point (Step 18) — If the Secu-
rity Level is not set to 0, the minimum cooling set point will be
in effect. The user will not be allowed to set the cooling set
point below the specified value. The range of values is 35 to
99 F (1 to 37 C). The default is 65 F (18 C).

Install Accessories —
be used with this thermostat:
• remote temperature sensor with override
(33CSSEN-WB)
• remote temperature sensor (33CSSEN-01)
• Add-a-Wire™ accessory (33CSACC-AW)
• duct temperature sensor (33CSSEN-DS)
• Add-a-Subzone™ accessory (33CSACC-AZ)
• wireless remote sensor (33CSRFS-RC/RE)
Refer to the accessory installation instructions for each
accessory for more information.
REMOTE TEMPERATURE SENSOR — A remote temper-
ature sensor may be provided to read the temperature from a
space. If a remote temperature sensor is connected, the thermo-
stat will ignore the reading of its internal sensor. When the ther-
mostat is using a reading from a remote sensor, the degree sym-
bol above the temperature reading will blink.
When installing a remote sensor, do not run the wires in the
same conduit as the HVAC equipment control wires, fire alarm
wiring, or other high voltage wiring. Do not use building
metalwork as a ground. Use only unshielded wire.
NOTE: Sensors can only be averaged when using a wireless
remote sensor (33CSRFS-RC/RE).
