This parameter is the calculated value for the outdoor air enthalpy
OUTSIDE AIR HUMIDITY
This parameter gives the current value of the OUTSIDE AIR
HUMIDITY input
OUTSIDE AIR HUMIDITY SENSOR INSTALLED
This parameters identifies to the Unit Controller that an outdoor air
humidity sensor is installed
OUTSIDE AIR TEMP
This parameter gives the current value for the OUTDOOR AIR
TEMPERATURE input
POWER EXHAUST INSTALLED
This parameter must be turned On to enable power exhaust operation
