UNIT CONFIGURATION
4.2.2 I/O Configuration
If using CO2/VOC or Duct Static Pressure to control the fans, enable the sensors here and
adjust the scaling if needed. These are user supplied sensors. The CO2 or VOC sensors may
also be used strictly for monitoring.
If either heating or cooling was enabled, the unit also requires a CA Temperature sensor in the
discharge air duct. This may be included if heating or cooling was ordered with the unit but will
have to be placed in the duct.
If the unit dehumidifies and requires reheat with Hot Gas Reheat or the heat source, a Coil
Leaving Temperature Sensor is required. If a HGRH coil was ordered with the unit this sensor
will be included.
4.2.3 Field-Installed Sensors and General Wiring
All sensors are wired to an intermediate terminal, as shown. They factory wiring connects to the
controller itself. It is shown for troubleshooting purposes but should not be changed.
