TEMP SYSTEM THERMOSTAT DISPLAY

The TEMP system thermostat is capable of different display
modes. The user can decide which display mode the TEMP
system thermostat will operate in. Information is displayed on
the TEMP system thermostat LCD screen. In normal operating
mode, the system status display is shown.
System Status Display —
shown during normal operation. The display cycles between
the heating and cooling set points and the room temperature
when the Rotating Display option is ON. When the Rotating
Display option is OFF, the thermostat will only display the
heating and cooling set points.
When the fan relay of the relay pack is energized, the word
FAN will be displayed on the TEMP system thermostat screen.
When cooling relay is energized, the word COOL will be
displayed on the TEMP system thermostat screen. When heat-
ing relay is energized, the word HEAT will be displayed on the
TEMP system thermostat screen.
NOTE: The TEMP system thermostat only controls the relay
pack. There is no feedback between the heating/ cooling equip-
ment and the relay pack.
When the second stage of heating or cooling is entered, a
decimal point is displayed between the current heating and
cooling set points.
If a data variable is forced by control software or data trans-
fer, then an ''F'' will be displayed on the screen during Alter-
nate Information display.
The display will show "UFLO" when a sensor is reading
out of the normal operating range. This would indicate that ei-
ther the sensor is malfunctioning or is out of calibration. If the
sensor is a pressure sensor, the pressure may be too low or too
high to read.
If error code display is turned on and the zone is participat-
ing in IAQ, then the display will show ''IA9'' to reflect IAQ
mode. It will also display normal errors.
More information can be shown by using the Alternate In-
formation Display function. The status of each element below
the address of the TEMP system thermostat can be seen by ac-
tivating a Communication Check.
Rotating Display —
The Rotating Display option con-
trols what information is shown on the display screen during
normal operation. When Rotating Display is ON, the heating
and cooling set points and the zone temperature are displayed.
When Rotating Display is OFF, only the heating and cooling
set points are shown. The Rotating Display option is config-
ured in category 1, option 5.
Electronic Timeclock —
stat may be equipped with an electronic timeclock. The time-
clock is used for operation of the TEMP system thermostat un-
occupied/occupied time periods. The timeclock is also used for
broadcast to other devices on the network.
To set the clock, remove the thermostat cover. On the right
side of the TEMP system thermostat, a select and an adjust but-
ton are provided under the timeclock. 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 but-
ton. 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. Re-install the thermostat
cover.
NOTE: If the TEMP system thermostat receives time from a
network device, the TEMP system thermostat time will revert
back to network time after the transmission.

Alternate Information Display —
system thermostat to display additional information. Simulta-
neously press the cooling or heating set point buttons, and the
TEMP system thermostat will display a sequence of informa-
tion. The information displayed is determined by the configu-
ration setting of Alternate Information. The display can be
frozen by pushing any set point button during the display
sequence.
The Alternate Information option can be set to ON or OFF.
To configure, set category to 7 and option to 3. Use the left set
point buttons to toggle the option ON or OFF.
When Alternate Information is ON and the Alternate Infor-
mation Display mode is activated, the TEMP system thermo-
stat will display the following information (if available) in this
order:
• (1) zone temperature
• (2) time of day
• (3) security level
• (4) duct temperature
• (5) outside-air temperature
• (6) outside-air relative humidity
• (7) indoor-air relative humidity
• (8) DX (direct expansion) coil temperature
• (9) filter status (digital input)
• (10) fan status (digital input)
• (11) IAQ status (digital input)
The information is shown on the top half of the display
screen. The number of the sequence (1-11) is shown in the bot-
tom right corner to help distinguish what is being displayed.
The numbering is not shown when the Alternate Information
option is turned OFF.
When Alternate Information is OFF and the Information
Display mode is activated, the TEMP system thermostat will
display the following information (if available) in this order:
• zone temperature
• time of day
• security level
Display Freeze —
abled when the Alternate Information option is ON. After In-
formation Display is activated, press any set point button to
freeze the display on the information shown when the set point
button was pressed. Press a set point button to resume the In-
formation Display sequence.
NOTE: Normal operation of the TEMP system thermostat is
not affected by the Display Freeze or Information Display
operations.
The start-up category for configuration contains important
communication, security, and operation information which the
TEMP system thermostat will need to operate correctly.
NOTE: The start-up category will display first when program
mode is activated, on initial power up to the thermostat or
when the device address is set to 0.
Device Address —
tem thermostat is accomplished via the network. The TEMP
system thermostat utilizes the network to:
• to receive data from the associated TEMP system thermo-
stats on the network
• receive configuration via software
The Device Address option allows the TEMP system ther-
mostat to establish an identity on the Carrier network for trans-
mitting and receiving information. The device address is set in
category 8, option 1. The factory setting is 0. Use the left set
point buttons to raise and lower the device address until the
correct address is shown on the TEMP system thermostat.
