DEFINITION
OCC ZONE COOLING SETPOINT
This parameter is programmed using the Setpoints key. This is the temperature
that the Primary Unit Controller compares the actual space temperature to, to
decide when to switch into the Occupied Cooling Mode.
OCC ZONE HEATING SETPOINT
This parameter is programmed using the Setpoints key. This is the temperature
that the Primary Unit Controller compares the actual space temperature to, to
decide when to switch into the Occupied Heating Mode.
OUTSIDE AIR ENTHALPY
This is a derived value and indicates the total heat content of the outdoor air.
OUTSIDE AIR ENTHALPY SETP
This parameter is programmed through the Setpoints key and is the upper limit
of outdoor enthalpy that can be used for economizer operation. If the outdoor air
enthalpy is above this value the economizer is made inactive.
OUTSIDE AIR HUMIDITY
This is the outdoor air relative humidity.
OUTSIDE AIR TEMP
This is the outdoor air dry bulb temperature.
P1 BAUD RATE
This parameter is programmed through the Service key. This establishes the
speed at which the Unit Controller communicates with a BAS system for com-
munication Port 1.
P1 MANUAL MAC ADDRESS
This parameter is programmed through the Service key. It can be used in place
of the dip switches on the I/O board to set the MAC address for Port 1. The
default value is -1 which allows the use of the dip switches to set the address.
P1 PARITY
This parameter is programmed through the Service key. It is used to set the Par-
ity for Port 1.
P1 PROTOCOL
This parameter is programmed through the Service key. It is used to set the
Protocol for Port 1.
P1 STOP BITS
This parameter is programmed through the Service key. It is used to set the
Stop Bits for Port 1.
P2 BAUD RATE
This parameter is programmed through the Service key. This establishes the
speed at which the Unit Controller communicates with a BAS system for com-
munication Port 2.
P2 MANUAL MAC ADDRESS
This parameter is programmed through the Service key. It can be used in place
of the dip switches on the I/O board to set the MAC address for Port 2. The
default value is -1 which allows the use of the dip switches to set the address.
P2 PARITY
This parameter is programmed through the Service key. It is used to set the Par-
ity for Port 2.
P2 PROTOCOL
This parameter is programmed through the Service key. It is used to set the
Protocol for Port 2.
P2 STOP BITS
This parameter is programmed through the Service key. It is used to set the
Stop Bits for Port 2.
PIEZOMETER RING
The Piezometer Ring Airflow Measuring System is now available as an acces
-
sory for housed and plenum fans. The system consists of a Piezometer ring
mounted at the throat and a static pressure tap mounted on the face of the inlet
cone. A differential pressure transducer and digital display can also be provided.
PRESSURES - DISCHARGE A
This is the discharge pressure for compressor A.
PRESSURES - DISCHARGE B
This is the discharge pressure for compressor B.
PRESSURES - DISCHARGE C
This is the discharge pressure for compressor C.
PRESSURES - DISCHARGE D
This is the discharge pressure for compressor D.
PRESSURES - DISCHARGE E
This is the discharge pressure for compressor E.
PRESSURES - DISCHARGE F
This is the discharge pressure for compressor F.
PRESSURES - SUCTION A
This is the suction pressure for compressor A.
PRESSURES - SUCTION B
This is the suction pressure for compressor B.
PRESSURES - SUCTION C
This is the suction pressure for compressor C.
