Status Table
-- The following sections describe the com-
puter status screen which is used to determine status the zone
controllec The screens shown may be displayed differently
when using different Carrier soflwme. See Table 4.
TERMINAL MODE -- The terminal mode is determined by
the equipment mode as reported by linkage and space require-
ments determined by space temperature and set points. The
ZONE_BAL and COMMISS modes am the result of the
activating the commissioning maintenance table to perform
terminal testing and commissioning.
Terminal Mode:Display Units ASCII
Default Value COOL
Display Range HEAT. COOL, VENT,

Network Access Read only
TERMINAL TYPE--Terminal type is the confirmation of
the terminal type configuration in the CONFIG Service Config
table.
Terminal Type: Display Units ASCII
Default value SINGLDUCT
Display Range SINGLDUCT. PAR
FAN, SER FAN
Network Access Read only
CONTROLLING SETPOINT -- Controlling Set Point will
display either the heating master reference or the cooling mas-
ter reference depending upon what mode the terminal is in. The
display will default to the heating master reference and display
the last controlling master reference when in neifller heating
nor cooling.
Controlling

Display Units F (C)
Default Value -40
Display Range -40 to 245
Network Access Read only
SPACE TEMPERATURE --Space temperature from 10 k_)
thermistor (Type II) located in the space.
Space
Temperature: Display Units F (C)
Default Value -40.0
Display Range -40.0 to 245.0
Network Access Read/Write
DAMPER POSITION- Damper position percent range of
rotation determined by the transducer calibration procedure.
The zone controller is designed be used on dalnpers with any
range of rotation.
Damper
Position:
Display Units % open
Default Value 0
Display Range 0 to 100
Network Access Read only
SUPPLY AIR TEMPERATURE -- Temperature of the air
leaving the zone controller downstremn of any ducted heat
source. Measured by a 10 k_2 thermistor (Type II). This tem-
perature is used to control the maximum dischmge air to the
space when local heat is active. The sensor is not required or
recommended for cooling only terminals. If supply air temper-
ature display is required by specification, on a cooling only
box, a heat type other than zero must be configured. This
will have no adverse affect on the operation of a cooling only
terminal.
Supply
Air Temperature: Display Units F (C)
Default Value 0.0
Display Range -40.0 to 245.0
Network Access Read/Write
LOCAL HEATING CAPACITY -- When loc_d heat at the
terminal is enabled the percent of heat being delivered is deter-
mined by the following formula for modulating (floating point)
type heat:
% Capacity = [(SAT - SPT)/(Maximum Duct Temp - SPT)]
The percent of heat delivered is determined by the follow-
ing for two-position hot water or staged electric heat:
% Output Capacity = (no. of active stages/Totedstages) * 100
Local Heating
Capacity: Display Units % output capacity
Default Value 0
Display range 0 to 100
Network Access Read only
TERMINAL FAN -- The commanded output for the termimd
fan on a fan powered terminal.
Terminal Fan: Display Units Discrete ASCII
Default Value Off
Display Range Off/On
Network Access Read/Write
RELATIVE HUMIDITY- Space Relative Humidity read-
ing from the optional relative humidity sensor The humidity
reading is used for display and monitoring purposes only.
Relative
Humidity: Display Units % RH
Default Value 0
Display Range 0 to 100
Network Access Read/Write
DEMAND VENTILATION--This variable displays the
amount of CO 2 in the air as read fiom the demand ventilation
sensor if DCV (demand control ventilation) is specified.
NOTE: The zone controller either reads relative humidity or
demand ventilation depending on what is specified in the Con-
trol Options configuration. If this point is not specifed, it is
awtilable for use as a soflwme point.
Demand
Ventilation: Display Units ppm
Default Value 0
Display Range 0 to 5000
