Notes:
1. MOC (Max Operating Current) is VFD Input Current when fan motors are
operating at FLA
2. MOC for dual DDP supply fans without bypass represents the total VFD input
current for both supply fan motors.
3. Dual DDP fans selected under 1,700 RPM will have 6-pole motors

Field Installed Control Wiring
The IntelliPak rooftop has many operating modes. The
flexibility of having several system modes depends
upon the type of sensor and/or remote panel selected
to interface with the Symbio 800. An overall layout of
the various control options available for a Single Zone
application, with the required number of conductors for
each device, is illustrated beginning with . Figure 32, p.
52 illustrates the various control options with the
required number of conductors for a Variable Air
Volume application.
NNoottee:: All field wiring must conform to NEC guidelines
as well as state and local codes.
