A Guide To Operating
Your TEMP System
NOTE TO INSTALLER
This manual should be left with the equipment owner.
GENERAL
This manual will assist you in using your Carrier Comfort
System thermostat. There is one basic type of thermostat that
you may encounter. It is called a TEMP system thermostat
and may be equipped with or without a timeclock.
The TEMPsystem thermostat can be identified by the sys-
tem switches (FAN, HEAT, COOL) which are located along
the bottom edge of the front cover. The TEMP system ther-
mostat can be equipped with or without a timeclock. The
timeclock display is located in the upper right corner. The
set point and room temperature display is located in the up-
per left corner. The set point and programming buttons are
located around the display.
There are three typical operations you may perform on
your TEMP system thermostat:
• change set points for heating and cooling
• override the unoccupied schedule
• change occupancy schedules
NOTE: Your ability to perform these functions may be lim-
ited by the security access level function which is config-
ured by the installer. If ‘‘access denied’’is shown on the dis-
play screen, you are not allowed to access that function.
OPERATION
Electronic Timeclock — To set the clock, remove the
cover of the thermostat. Two buttons, located under the time-
clock, are provided to set the clock. They are labeled select
and adjust. Press the select button. The minutes setting on
the clock will flash. Press the adjust button until the correct
minutes are shown. Press the select button. The hour setting
will flash. Press the adjust button until the correct hour is
shown (includingAM and PM). Press the select button again
and the day of the week will flash. Press the adjust button
until the correct day is shown. Press the select button to re-
turn to normal timeclock operation.
System Switches — The TEMPsystem thermostat op-
eration mode is controlled by 3 system switches: FAN, HEAT,
COOL. See Fig. 1.
The FAN switch can be set to ON or AUTO. When the
FAN switch set to ON, the fan will run continuously. When
the FAN switch is set toAUTO, the fan will only run during
heating and cooling.
The COOL switch can be set to OFF orAUTO. When the
COOL switch set to OFF, the TEMP system will not enter
cooling mode. When the COOL switch is set to AUTO, the
TEMP system will enter cooling mode when the zone tem-
perature rises above the cooling set point.
The HEAT switch can be set to OFF or AUTO. When the
HEAT switch set to OFF, the TEMP system will not enter
heating mode. When the HEAT switch is set to AUTO, the
TEMP system will enter heating mode when the zone tem-
perature drops below the heating set point.

System Displays — The TEMP system thermostat has
a display window which is used to show system information
and for programming mode. See Fig. 1.
SET POINTDISPLAY —The heating and cooling set points
are shown in the display window during the normal display
mode. The heating and cooling set points are used to deter-
mine the range of temperatures that are maintained in the
zone.
The cooling set point buttons are located on the left side
of the display screen. The heating set point buttons are lo-
cated on the right side of the display screen.
MODE DISPLAY — When the system fan is energized, the
word FAN appears on the display screen.
When the cooling mode is energized, the word COOL ap-
pears on the display screen. The system fan will also be en-
ergized.
When the heating mode is energized, the word HEAT ap-
pears on the display screen. The system fan will also be en-
ergized, unless it is configured not to run during heating mode.
If the system enters IAQ (Indoor Air Quality) mode, the
word IA9 appears on the display screen.
ALTERNATE DISPLAY— By pressing both cooling or heat-
ing set point buttons simultaneously, the alternate informa-
tion display is activated. The TEMP system thermostat will
display the current zone temperature and then the time of
day. If theAlternate Display function has been configured to
ON, the TEMP system thermostat will show more detailed
zone information. The display will then return to normal.
Adjustment of Set Points — The cooling and heat-
ing set points are configured through the set point buttons.
The heating set point buttons are located on the right side
of the display screen. Press the upper button to raise the heat-
ing set point temperature. Press the lower button to lower
the heating set point temperature. The heating set point is
limited to a range of 66 to 80 F by the TEMP system.
The cooling set point buttons are located on the left side
of the display screen. Press the upper button to raise the cool-
ing set point temperature. Press the lower button to lower
the cooling set point temperature. The cooling set point is
limited to a range of 66 to 80 F by the TEMP system.
NOTE: The heating and cooling set point ranges can be con-
figured to smaller ranges.
The heating and cooling set points may be set for the same
temperature, but the thermostat will not allow the cooling
set point to be adjusted lower than the heating set point, or
the heating set point to be adjusted higher than the cooling
set point.
Operating Modes — The TEMPsystem thermostat has
3 operating modes: occupied mode, unoccupied mode, and
unoccupied override. Occupied mode is the mode used when
the area is normally occupied. Unoccupied mode is used to
conserve energy and is used when the area is normally un-
occupied. Unoccupied Override is used to temporarily over-
ride unoccupied mode when an area is in use during the un-
occupied schedule time. The user can manually activate
unoccupied override. Set points can be adjusted during both
occupied and unoccupied override modes.
The occupied schedule controls when the zone is in oc-
cupied or unoccupied mode. The schedule can be sent from
a device over the network, or it can be programmed at the
TEMP system thermostat.
UNOCCUPIED OVERRIDE — Unoccupied override is used
to temporarily change the system set points to the occupied
mode set points. An example of unoccupied override would
be a worker staying past 6:00 PM to finish a job when the
scheduled unoccupied time is 6:00 PM.
To override unoccupied mode, press a set point button.
The unoccupied display will be replaced with the occupied
mode display. The TEMP system thermostat will automati-
cally return to unoccupied mode when the override timer
expires.

Occupancy Schedule — The occupancy schedule es-
tablishes the time periods when the TEMP system thermo-
stat operates in the occupied or unoccupied mode.
The unoccupied/occupied schedule has individual 7-day
programming with 8 time periods. Unoccupied/occupied ON/
OFF times are entered on the minute. The start of an ON
time is the beginning of the occupied mode. The start of an
OFF time is the beginning of the unoccupied mode.
NOTE: If an ON time and an OFF time are set for the same
time, the TEMP system thermostat operates in unoccupied
mode for that entire period.
NOTE: Access to the occupancy schedule by certain users
may be limited through the security level access function.
CONFIGURATION OF SCHEDULES — The unoccupied/
occupied program can be directly configured at the TEMP
system thermostat. To configure the schedule, perform the
following:
