Human Interface Panel (HI)
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
unit must be equipped with an optional
InterProcessor Communications Bridge
(IPCB). The RHI can be located up to
1,000 feet from the unit. A single RHI can
be used to monitor and control up to 4
rooftops, each containing an IPCB.
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 (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.
Emergency Override Definitions with
LCI-I (LonTalk Communication Interface
for IntelliPak) module installed
When an LCI-I module is installed, the
user can initiate one of five (5)
Emergency Override sqeuences that
have the following predefined unit
operation:
