MENU ITEM

DEFINITION

SUPPLY SYS STATUS

This is the active status of the Supply System, display will show Normal- Active;

Normal-Inactive; Safety Trip, Safety Fault, or Safety Lockout.

SYSTEM UNLOADING PRESSURE

This parameter is programmed through the SETPOINTS key. If two compressors

of the system are operative and the discharge pressure is equal to or greater than

this value the Unit Controller will turn off one of the compressors. This feature is

only operative when a discharge pressure transducer is installed in the compressor
system.

(THIS FEATURE IS NOT AVAILABLE ON THIS UNIT)

TEMPERATURE SUPERHEAT

This is calculated for each compressor system that has a suction line pressure

transducer installed and configured. This is the refrigerant evaporator superheat

leaving the evaporator coil.

(THIS FEATURE IS NOT AVAILABLE ON THIS UNIT)

UNDERFLOOR AIR HUMIDITY

This is the humidity level under the floor of a FlexSys installation.

UNDERFLOOR AIR TEMP

This is the temperature of the air in the underfloor space.

UNDERFLOOR SLAB DEW POINT

This is the dewpoint of the air beneath the floor of a FlexSys installation.

UNDERFLOOR SLAB TEMP

This is the temperature of the slab beneath the floor of a FlexSys installation.

UNIT INSTALLED ALTITUDE

This parameter is programmed through the SETPOINTS key. This is the altitude
at which the unit is installed. This is used in the calculation of an airflow correction

factory when air measuring stations are installed.

(THIS FEATURE IS NOT AVAILABLE ON THIS UNIT)

UNIT SIZE

This parameter is programmed through the OPTIONS key and identifies the size of

the unit. The choices are 50 Ton, 55 Ton, 60 Ton, 65 Ton, 70 Ton, 75 Ton, 80 Ton, 85
Ton, 90 Ton, 95 Ton, 105 Ton, 106 Ton, 110 Ton, 115 Ton, 130 Ton, or 150 Ton.

UNIT TYPE

This parameter is programmed through the OPTIONS key and identifies the type of

unit. The choices are Constant Volume, Variable Volume, or FlexSys.

UNIT-OVERALL STATUS

This is the active status of the Unit. The display will show Local Stop, Run, Unit Trip,

Unit Fault, Unit Lockout, SMK Purge # - Press, SMK Purge #-Purge, Smk Purge

#-Evac, or Unstable system.

VENT SYS STATUS

This is the active status of the Ventilation System. The display will show Normal-

Active, Normal-Inactive, Safety Trip, Safety Fault, Safety Lockout, User Disabled,

or None.

VENTILATION CONTROL

This parameter is programmed through the OPTIONS key and identifies whether the

unit will operate with a Fixed Minimum or Demand ventilation system.

VENTILATION DEMAND

This is the output in percent to the outside air damper when the unit is operating in
the Demand Ventilation mode.

ZONE TEMP CURRENT

This is the temperature in the conditioned space.

ZONE TEMP OCC ZONE COOLING
SETPOINT

This parameter is programmed using the SETPOINTS key. This is the temperature

that the Unit Controller compares the actual space temperature to, to decide when
to switch into the Occupied Cooling Mode.

ZONE TEMP OCC ZONE HEATING
SETPOINT

This parameter is programmed using the SETPOINTS key. This is the temperature

that the Unit Controller compares the actual space temperature to, to decide when
to switch into the Occupied Heating Mode.

ZONE TEMP UNOCC ZONE COOLING
SETPOINT

This parameter is programmed using the SETPOINTS key. This is the temperature

that the Unit Controller compares the actual space temperature to, to decide when
to switch into the Unoccupied Cooling Mode.

ZONE TEMP UNOCC ZONE HEATING
SETPOINT

This parameter is programmed using the SETPOINTS key. This is the temperature

that the Unit Controller compares the actual space temperature to, to decide when
to switch into the Unoccupied Heating Mode.
