guide vanes open and the exhaust fan should be turned off.

-Supply fan - On.

-Supply fan VFD - On (60 Hz) (if equipped)

-Inlet guide vanes/VAV boxes - Open (if equipped).

-Exhaust fan - Off, exhaust dampers - Closed (if equipped).

-Exhaust fan VFD - Off (0 Hz) (if equipped)

-Outside air dampers - Open.

-Heat - all stages - Off, Modulating heat output at 0 vdc.

-Occupied/Unoccupied output - Energized

-VO relay - Energized

EXHAUST sequence “C”

With only the exhaust fans running (supply fan off), the space that is conditioned by that rooftop would become negatively pressurized.This is desirable for clearing the area of smoke from the now-extinguished fire, possibly keeping smoke out of areas that were not damaged.

-Supply fan - Off.

-Supply fan VFD - Off (0 Hz) (if equipped)

-Inlet guide vanes - Closed (if equipped).

-Exhaust fan - On, exhaust dampers - Open (if equipped).

-Exhaust fan VFD - On (60 Hz) (if equipped)

-Outside air dampers - Closed.

-Heat - all stages - Off, Modulating heat output at 0 vdc.

-Occupied/Unoccupied output - Deenergized

-VO relay - Energized

PURGE sequence “D”

Possibly this sequence could be used for purging the air out of a building before coming out of Unoccupied mode of operation on VAV units or when the purging of smoke or stale air is required after a fire.

-Supply fan - On.

-Supply fan VFD - On (60 Hz) (if equipped)

-Inlet guide vanes/VAV boxes - Open (if equipped).

- Exhaust fan - On, exhaust dampers - Open (if equipped).

-Exhaust fan VFD - On (60 Hz) (if equipped)

-Outside air dampers - Open.

-Heat - all stages - Off, Modulating heat output at 0 vdc.

-Occupied/Unoccupied output - Energized

-VO relay - Energized

PURGE with duct pressure control “E”

This sequence can be used when supply air control is required for smoke control.

-Supply fan - On.

-Supply fan VFD - On (if equipped)

-Inlet guide vanes/VFD controlled by supply air pressure control function with supply air pressure high limit disabled.

-Exhaust fan - On, exhaust dampers - Open (if equipped).

-Exhaust fan VFD - On (60 Hz) (if equipped)

-Outside air dampers - Open.

-Heat - all stages - Off, Modulating heat output at 0 vdc.

-Occupied/Unoccupied output - Energized

-VO relay - Energized

Note: Each system (cooling, exhaust, supply air, etc.) within the unit can be redefined in the field for each of the five sequences, if required. Also the definitions of any or all of the (5) five sequences may be locked into the software by simple key strokes at the Human Interface Panel.

Human Interface Panel (H.I.)

The Human Interface (HI) Panel provides a 2 line X 40 character clear English liquid crystal display and a 16 button keypad for monitoring, setting, editing and controlling.The Human Interface Panel is mounted in the unit’s main control panel and is accessible through a hatch built into the unit’s control panel door.

The optional remote-mount version of the Human Interface (RHI) Panel has all the functions of the unit-mount version except Service Mode.To use a RHI the
