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 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 .
illustrates the various control options with the required
number of conductors for a Variable Air Volume application.
Note: All field wiring must conform to NEC guidelines as
well as state and local codes.
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.

Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements
for field wiring installation and grounding as
described in NEC and your local/state/national
electrical codes.
The various field installed control panels, sensors,
switches, and contacts discussed in this section require
both AC and DC consideration. These diagrams are
representative of standard applications and are provided
for general reference only. Always refer to the wiring
diagram that shipped with the unit for specific electrical
schematic and connection information.
Controls using 24 VAC
