selection switch for constant volume units is in the
Auto position. (VAV and SZVAV units do not utilize
a “Fan” selection input.)
2. Close the disconnect switch or circuit protector
switch that provides the supply power to the unit
terminal block 1TB1 or the unit mounted disconnect
switch 1S14.
3. Turn the 115 volt control circuit switch 1S2 and the
24 volt control circuit switch 1S3 to the On position.
4. Open the Human Interface access door, located in

Human Interface designator.
6. Once the configuration for the Fans is complete,
press the NEXT key until the LCD displays the “Start
