SECTION 7 – PARAMETER DESCRIPTIONS AND OPTIONS
TABLE 36 – DEFINITIONS (CONT'D)
MENU ITEM DEFINITION
PRE-OCCUPANCY PURGE TIME (hours of day)
This parameter establishes the number of hours prior to the occupied
start time that the PRE-OCCUPANCY PURGE would start
PRE-OCCUPANCY PURGE TIME (minutes of day)
This parameter establishes the number of minutes prior to the
occupied start time that the PRE-OCCUPANCY PURGE would start
PURGE SWITCH This is the status of the binary input to terminal purge - purge mode
REDLINE
This feature can be used to temporally reduce the electrical
consumption of the unit by turning off some of the active compressors.
This feature is only available through a communicated input.
REMOTE CONTROL INPUT ENABLE FOR THIRD
PARTY BAS This allows the use of an external 0 to 10VDC signal to reset the
supply air temperature setpoint on VAV units.
REMOTE CONTROL INPUT VALUE
Gives the value of the 0 to 10VDC remote control input for the remote
control of the dampers
RETURN AIR ENTHALPY This parameter is the calculated value for the return air enthalpy
RETURN AIR HUMIDITY
This parameter gives the current value of the RETURN AIR
HUMIDITY input
RETURN AIR HUMIDITY SENSOR INSTALLED
This is the return enthalpy setting which the Unit Controller uses to
determine when to switch into economizer operation in dual enthalpy
economizer mode
RETURN AIR TEMP
This parameter give the current value for the RETURN AIR
TEMPERATURE input
RUN TEST
By turning this feature on the Unit Controller sequencing on all the
binary outputs to verify operation of the unit electrical devices
SENSOR SPACE TEMPERATURE SENSOR
OUTSET This is the actual space sensor offset amount being used by the Unit
Controller in degrees.
SPACE SENSOR DETECTED
Identifies if the Unit Controller has detected the presence of a space
sensor. If the Unit Controller detects a space sensor it will self
configure to use it for control of the unit.
SPACE SENSOR FAULT OVERRIDE ENABLE
When this option is turned ON the controller uses the return air
temperature input in place of the space temperature input to control
the unit. Turing this option on allows the unit to operate in a VAV
stand alone mode
SPACE TEMP
This parameter gives the current value of the SPACE TEMPERATURE
input
SPACE TEMP TRENDING ALARM TEMP
To enable this feature the parameter must be set to other than 0.
A value other than 0 is the number of degrees above or below the
setpoint the temperature must be to start the timing
SPACE TEMP TRENDING ALARM TIME
This parameter established the amount of time the Space
Temperature must be trending above or below the SPACE TEMP
TRENDING ALARM TEMP before the alarm will be initiated.
SPACE TEMPERATURE OFFSET RANGE
This setpoint establishes the maximum amount of heating or cooling
reset available through the reset feature on a space sensor.
STAGES OF HEAT AVAILABLE
This parameter identifies the number of stages of heat the Unit
Controller is set up to control
STATE COMPRESSOR OFF - LOW SUPPLY
VOLTAGE This identifies the compressors are off because of low supply voltage.
ON when this state is active
STATE COMPRESSORS OFF - LOW AMBIENT
TEMPERATURE
This identifies the compressor are off because the outdoor
temperature is below the low ambient lockout temperature. ON when
this state is active
STATUS COMPRESSOR OFF - ECON IS USING
FREE COOLING This identifies the compressors are off because the Unit Controller is
using outdoor air for cooling. ON when this is active
