Step 6 - Check Thermostat Operation; Step 7 - Select Thermostat Operation; Settings; Step 8 - Set Current Time - Carrier 33CS Installation, Start-Up, And Operating Instructions Manual

FAHRENHEIT OR CELSIUS SELECTION — The ther-
mostat can be set to use a Celsius or Fahrenheit temperature
display. Press the Change Day button in configuration mode
to access the parameter. Use the Up and Down buttons on
the thermostat to change the setting between F (Fahrenheit)
and C (Celsius). The default value is F.
FAN ON OR OFF WHEN HEAT IS ENERGIZED SELEC-
TION — The thermostat can be set to turn the fan (G out-
put) on or off when the heat input (terminal W) is energized.
Press the Hold button while in configuration mode to access
the parameter. Use the Up and Down buttons to toggle be-
tween OF (fan off during heating) and ON (fan on during
heating). The default value is ON. The W relay option only
cycles the fan when the fan is in the Auto Mode and the
''Fan ON When Heat Energized'' option is configured to ON.
HIGH AMBIENT ELECTRIC HEAT LOCKOUT SELEC-
TION — If DIP switch A is set to ON (heat pump) and
DIP switch C is set to OFF (an outdoor temperature sensor
is present), electric heat can be locked out if the outdoor
ambient temperature rises above the user-defined value.
Temperatures of 15 to 55 F (in 5-degree increments) can be
selected. The lockout can also be disabled. The default is OF
(disabled). Emergency heat mode disables this function. Press
the Copy Previous Day button in the configuration mode to
access the parameter. Use the Up and Down buttons to in-
crease or decrease the setting.
CLEAN FILTER TIMER SELECTION — The clean filter
selection determines how many hours of fan operation will
pass before the Clean Filter icon is displayed. A timer in the
thermostat accumulates the total fan operation hours. The
range of values is 400 to 3600 hours (in 400-hour
increments).
• a ''1'' will be displayed for 400 hours of operation
• a ''2'' will be displayed for 800 hours of operation
• a ''3'' will be displayed for 1200 hours of operation
• a ''4'' will be displayed for 1600 hours of operation
• a ''5'' will be displayed for 2000 hours of operation
• a ''6'' will be displayed for 2400 hours of operation
• a ''7'' will be displayed for 2800 hours of operation
• a ''8'' will be displayed for 3200 hours of operation
• a ''9'' will be displayed for 3600 hours of operation
The selection can also be set to OF (disabled). Press the
Reset Filter button in the configuration mode to access the
parameter. Use the Up and Down buttons to change the set-
ting. The default is 2 (800 hours).
NOTE: During the selection procedure, the Clean Filter icon
will be displayed, even if OF (disabled) is chosen.
ANTICIPATOR ADJUSTMENT SELECTION — The an-
ticipator adjustment controls the sensitivity and cycle rate of
the thermostat. Higher numbers decrease the sensitivity and
slow the cycle rate (longer cycle times). Lower numbers in-
crease sensitivity and speed up the cycle rate (shorter cycle
times). Values can range from 1 to 9. The default is 3. The
default selection will provide optimum performance in nearly
all installations. Do not change the setting unless there is a
need to do so. Press the Mode button during configuration
mode to change the setting. Use the Up and Down buttons
to increase or decrease the value.
Unlike conventional thermostat anticipators, the setting is
not determined by current draw. There is no need to mea-
sure, know, or compensate for the current. There is no need
to ''droop'' with this thermostat, regardless of the anticipa-
tor setting.
KEYPAD LOCKOUT SELECTION — The thermostat has
a lockout feature which will not acknowledge configuration
buttons until the lockout code is entered. After the lockout
code has been entered, the keypad will remain unlocked un-
til the user has stopped pressing keys for 2 minutes. The Lock-
out selection can be set to ON or OF (disabled). Press the
Set Time key in configuration mode to change the setting.
Use the Up or Down buttons to toggle between off and on.
The default is OF.
NOTE: If the Lockout is enabled, the lockout code is as fol-
lows, in sequence, within a 10-second time period: Mode
button, Copy Previous Day button, Set Time button, and Hold
button.
LOW AMBIENT COOLING LOCKOUT SELECTION —
The Low Ambient Cooling Lockout Feature will lock out
cooling mode if the outdoor-air temperature is below the lock-
out cooling temperature (user-configured).
NOTE: This configuration is not available if DIP switch C
(Remote Room Sensor) is set to ON or if the outdoor air
sensor is in error.
The default is OF (disabled). The lockout temperature can
be set to OF (disabled) or 20 to 60 F in 5-degree increments
(enabled). To configure the selection, press the Program but-
ton in the configuration mode. Use the Up and Down but-
tons to increase or decrease the setting.
Step 6 — Check Thermostat Operation —
form the following procedure to check thermostat operation:
1. Press the Hold button. This will prevent the set point from
changing until the desired time and temperature schedule
is entered.
2. Press the Fan button to switch the fan annunciator from
AUTO to ON. The fan should run continuously. Check
fan operation. Press the fan button again to switch back
to AUTO.
3. Press the mode button repeatedly until HEAT is dis-
played in the mode annunciator. Press the Up button until
the set point reads 10 degrees above room temperature.
The heating system should begin to operate within
5 minutes.
4. Press the mode button repeatedly until COOL is dis-
played in the mode annunciator. Press the Down button
until the set point reads 10 degrees below room tempera-
ture. The cooling system should begin to operate within
