SAT RESET METHOD
This parameter is programmed through the OPTIONS key and identies the Supply Air
Temperature reset method being used on a Variable Air Volume Unit. The choices are
Hardwired, Outside Air, Return Air, or Supply Fan Speed.
SAT HIGH SETPOINT
This parameter is programmed through the SETPOINTS key. This establishes the maximum
Active Supply Air Temperature to be used in a Variable Air Volume Unit.
SAT LOW SETPOINT
This parameter is programmed through the SETPOINTS key. This establishes the minimum
Active Supply Air Temperature to be used in a Variable Air Volume Unit.
SENSOR / MISC STATUS
This is the current status of the Sensors. The display will show Normal, Warning, Safety Trip,
Safety Fault, or Safety Lockout.
SINGLE ZONE MINIMUM
VAV SPEED
This parameter provides the minimum speed of the Supple Fan during SZVAV operation.
SMOKE PURGE SEQ 1
This parameter is programmed through the OPTIONS key. This allows the user to select
which of the three smoke purge sequences to use a sequence 1, Purge, Pressurization, or
Evacuation. Smoke Purge Sequence 1 is energized through a Binary input to the IPU board.
SMOKE PURGE SEQ 2
This parameter is programmed through the OPTIONS key. This allows the user to select
which of the three smoke purge sequences to use a sequence 2, Purge, Pressurization, or
Evacuation. Smoke Purge Sequence 2 is energized through a Binary input to the IPU board.
SMOKE PURGE SEQ 3
This parameter is programmed through the OPTIONS key. This allows the user to select
which of the three smoke purge sequences to use a sequence 3, Purge, Pressurization, or
Evacuation. Smoke Purge Sequence 3 is energized through a Binary input to the IPU board.
1ST STAGE COOLING
SETPOINT
This parameter is programmed through the SETPOINTS key. This value is used in a Constant
Volumn unit as the Active SAT Setpoint for 1st Stage cooling operation.
1ST STAGE HEATING
SETPOINT
This parameter is programmed through the SETPOINTS key. This value is used in a Constant
Volumn unit as the Active SAT Setpoint for 1st Stage heating operation.
2ND STAGE 2 COOLING
SETPOINT
This parameter is programmed through the SETPOINTS key. This value is used in a Constant
Volumn unit as the Active SAT Setpoint for 2nd Stage cooling operation.
2ND STAGE 2 HEATING
SETPOINT
This parameter is programmed through the SETPOINTS key. This value is used in a Constant
Volumn unit as the Active SAT Setpoint for 2nd Stage heating operation.
STAGED HEAT STATUS
STGS ON
This identies the number of stages of gas or electric heat that the IPU board has energized.
STAGED HEAT STATUS
STGS AVAIL
This identies the number of stages of gas or electric heat that are available.
SUCTION TEMP
This is the temperature of the suction line leaving the evaporator coil and is shown for each
system. This value is monitored and used to prevent liquid refrigerant from being returned to
the compressor.
SUP AIR TEMPERING
This parameter is programmed through the PROGRAM key. This parameter is used to allow
the heat to operate when the unit is in the Occupied Standby mode to temper the ventilation air
entering the space. The choices are USER ENABLED or USER DISABLED.
SUPPLY AIR TEMP
ACTIVE SP
This is the Supply Air Temperature the IPU board is trying to maintain.
SUPPLY AIR TEMP
CURRENT
This is the current Supply Air Temperature supplied by the unit.
SUPPLY FAN OUTPUT This is the Binary output from the IPU board to the Supply Fan control system.
SUPPLY FAN OUTPUT
PROOF
This is a Binary input into the IPU board that identies the Supply Fan is functioning.
SUPPLY FAN VFD SPEED This indicates the output, in percent, to the Supply Fan VFD.
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 IPU board
will turn off one of the compressors. This feature is only operative when a discharge pressure
transducer is installed in the compressor system.
