*When using optional Outside Air Damper, must also have MAT/OAT
inputs (typically 10K, Type III thermistors). Ensure pull-up resistor
switch positions are set properly—see Illustration 3 on page 2.
**Fan Status (FST) or Discharge Air Temperature (DAT) is an optional,
selectable input. Ensure pull-up resistor switch positions are set
properly (10K position) for the relay, switch, or Type III thermistor.
