X DigitalOut[0] specifies which logical digital output function is assigned to the
digital physical output according to the enumerated list that is shown in the
Engineering Units/States column. The W7750 Controllers are configured at
the factory with the enumerated value in the Default column. Only
DigitalOut[0] through DigitalOut[5] are available in the W7750A model
which can configure staged outputs. The W7750A Controller can drive
Series 60 Floating Control to modulate cooling valves, heating valves and
economizers. (No PWM outputs are allowed in the W7750A model.) The
controller is configured at the factory with the enumerated value in the
Default column. The eight outputs on the W7750B are all digital outputs.
The eight outputs on the W7750C consist of five digital and three analog
outputs.
