TEMP SYSTEM THERMOSTAT DISPLAY

The TEMP system thermostat is capable of different dis-
play modes. The user can decide which display mode the
TEMP system thermostat will operate in. Information is dis-
played on the TEMP system thermostat LCD screen. In nor-
mal 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 re-
lay pack. There is no feedback between the heating/cooling
equipment 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 Al-
ternate Information display.
If error code display is turned on and the zone is partici-
pating 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
Information Display function. The status of each element be-
low the address of the TEMP system thermostat can be seen
by activating 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 heat-
ing and cooling set points and the zone temperature are dis-
played. When Rotating Display is OFF, only the heating and
cooling set points are shown. The Rotating Display option is
configured 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
unoccupied/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
button are provided under the timeclock. Press the select but-
ton. 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 opera-
tion. Re-install the thermostat cover.
NOTE: If the TEMP system thermostat receives time from
a network device, the TEMP system thermostat time will re-
vert back to network time after the transmission.
Alternate Information Display —
system thermostat to display additional information. Simul-
taneously press the cooling or heating set point buttons, and
the TEMP system thermostat will display a sequence of in-
formation. The information displayed is determined by the
configuration 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 In-
formation Display mode is activated, the TEMP system ther-
mostat 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
bottom right corner to help distinguish what is being dis-
played. The numbering is not shown when the Alternate In-
formation 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
Information 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 Information 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 impor-
tant communication, security, and operation information which
the TEMP system thermostat will need to operate correctly.
NOTE: The start-up category will display first when pro-
gram mode is activated, on initial power up to the thermo-
stat 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 ther-
mostats 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
transmitting 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 ad-
dress until the correct address is shown on the TEMP system
thermostat.
