Specifications
CONFIGURATION
Configuration can be done either manually with the set
point buttons on the monitor thermostat or by computer with
system network access software. Refer to each specific sec-
tion in this manual for detailed instructions on configuring
the monitor thermostat options. Refer to the software manual
for network software configuration.
A special start-up category of options (category 8.0) has
been designated as the start-up category. This category con-
tains options that must be configured correctly before the
monitor thermostat will operate correctly. After installation,
configure the start-up (8.0) category first. The start-up cat-
egory will automatically be displayed when entering pro-
gramming mode after the thermostat is powered up for
the first time or when the device and bus addresses are
both 0. Each device on each communication bus must have
a unique address.
Manual Configuration — To manually configure the
monitor thermostat, press both upper or both lower set point
buttons simultaneously. See Fig. 14 and 15. The configura-
tion screen will display the current category in the lower right
corner (numbered from 1 to 14). Press the left upper or lower
set point buttons to access the different configuration cat-
egories. Press the select (right lower set point) button to ac-
cept the current category for modification. The escape (right
upper set point) button can be used to return to the category
screen. The categories will loop around when scrolling from
14 back to 1.
The left upper and lower set point buttons are used to toggle
through the options of each category. The option number is
displayed in the lower right corner of the screen. See
Table 1 for categories and options. When the desired option
is shown on the screen, press the select button. The config-
urable data will flash. The left set point buttons are used to
toggle the data values. When the desired setting is shown
press the select button to store the change. To exit without
saving changes, press both upper or both lower set point but-
tons or press the escape button. If no buttons are pressed
while in programming mode for 3 minutes, the monitor-
thermostat will reset back to the normal display.
Each option is discussed in detail in this manual. Refer to
the correct section for more information.
Computer Configuration — To configure the moni-
tor thermostat with an IBM compatible computer, Carrier net-
work access software must be running.
MONITOR THERMOSTAT DISPLAY
The monitor thermostat is capable of different display modes.
The user can decide which display mode the monitor ther-
mostat will operate in. Information is displayed on the moni-
tor thermostat LCD (liquid crystal display) screen. In nor-
mal operating mode, the system status display is shown.
System Status Display — System status display is
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 monitor thermostat screen.
When cooling relay is energized, the word COOL will be
displayed on the monitor thermostat screen. When the heat-
ing relay is energized, the word HEAT will be displayed on
the monitor thermostat screen.
NOTE: The monitor 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 Al-
ternate Information display.
If error code display is turned on and a zone is partici-
pating in IAQ, then the display will show "IAg" to reflect
IAQ mode.
More information can be shown by using the Alternate
Information Display function. The error status of each zone
associated with the monitor thermostat system can shown
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. The default is OFF.
