TEMP System Thermostat with Timeclock

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 TEMP system thermostat can be identified by the system switches (FAN, HEAT, COOL) which are located along the bottom edge of the front cover. The TEMP system thermostat 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 upper 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 limited by the security access level function which is configured by the installer. If ‘‘access denied’’ is shown on the display screen, you are not allowed to access that function.

TEMP System Thermostat without Timeclock

OPERATION

Electronic Timeclock —

To set the clock, remove the cover of the thermostat. Two buttons, located under the timeclock, 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 (including AM 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 return to normal timeclock operation.

System Switches —

The TEMP system thermostat operation 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 to AUTO, the fan will only run during heating and cooling.

The COOL switch can be set to OFF or AUTO. 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 temperature 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 temperature drops below the heating set point.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Fig. 1 — TEMP System Thermostat Functions

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 POINT DISPLAY — 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 determine 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 located 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 appears on the display screen. The system fan will also be energized.

When the heating mode is energized, the word HEAT appears on the display screen. The system fan will also be energized, 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 heating set point buttons simultaneously, the alternate information display is activated. The TEMP system thermostat will display the current zone temperature and then the time of day. If the Alternate 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 heating 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 heating 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 cooling 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 configured 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 TEMP system 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 unoccupied. Unoccupied Override is used to temporarily override unoccupied mode when an area is in use during the unoccupied 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 occupied 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 automatically return to unoccupied mode when the override timer expires.

Occupancy Schedule —

The occupancy schedule establishes the time periods when the TEMP system thermostat 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:

1. Press both upper or lower set point buttons at the same time to enter into the program mode. The word ‘‘category’’ and the number 1 will be displayed. See Fig. 2 for the functions of the programming buttons.

2. Press the left upper set point button. The word ‘‘category’’ and the number 2 will be displayed. Category 2 contains the occupied/unoccupied schedules for the TEMP system thermostat.

3. The lower right set point button is the select button. Press the select button. The word ‘‘category’’ will change to

‘‘option’’ and the number 1 will be displayed. Category 2, options 1 through 8 are the 8 different occupancy time periods. Option 1 is occupied period 1. Option 2 is occupied period 2. The options continue to option 8 which is occupancy period 8.

4. The start time for option 1 will be shown. Each occupied period (options 2.1 through 2.8) will have three different screens associated with it: start time, stop time, and active days. Use the left set point buttons to scroll through the start time, stop time, and active days for each option.

Press the select button (right lower set point button) to modify the screen.

5. Configure the start time for category 2, option 1. When the select button is pressed from the start time screen, the hours number will flash. The hours are modified through the left set point buttons. The AM/PM modifier will automatically switch when scrolling through the times. To change the minutes, press the select button again. The minutes numbers will flash. Use the left set point buttons to modify the minutes. Press select again to save the current time and return to the options screen, or press escape (upper right set point button) to exit without saving changes.
