1. The OPEN side of the DIP switch is marked ‘‘OPEN.’’ When the
rocker switch is on the ‘‘OPEN’’ side of the switch, the switch is
OPEN.

switch 1. If DIPswitch 1 is set to OPEN(VAV operation), then DIP
switches 2 and 5 will configure VAV functions.
3. When the unit is field-tested (DIP switch 4 to OPEN), the function
of DIP switch 6 changes and itis used to set the minimum damper
