18.03.01. Compressors 24VAC External Control Mode
Compressors are configured through a 24VAC input from the external control. This is the
DEFAULT
compressor configuration. If this is the compressor external input requirement, no control interface
configuration is required. Refer to the wiring diagram for wiring connection.

18.03.02. Compressors 0-10VDC External Control Mode
Compressors can be controlled through a 0-10VDC input from the external control.
NOTE
If a 0-10V input is required the multi-input must be changed as shown per procedure.
Compressors Configuration Procedure for 0-10VDC External Control Mode:
Assign a Multi Input to the Compressors via
