Packaged Rooftop Air Conditioners Manual

RT-PRC010-EN98
the infrequent user when making
desired changes and an attractive
hinged door makes the RHI very
suitable for mounting on any wall. The
RHI can be mounted inside a building,
up to 5,000 feet from the unit. The RHI
is wired to the IPCB mounted in the
rooftop with twisted wire pair
communication wiring and 24V
control wiring.
• Ventilation Override Module (VOM) —
With the Ventilation Override Module
installed, the unit can be programmed
to transition to up to 5 different
programmed sequences for Smoke
Purge, Evacuation, Pressurization,
Purge, Purge with duct control
sequence and Unit off. The transition
occurs when a binary input on the
VOM is closed (shorted); this would
typically be a hard wired relay output
from a smoke detector or fire control
panel.
• Extended Grease Lines — Lines allow
greasing of supply and exhaust fan
bearings through the filter access door.
• Access Doors — Hinged access doors
provide easy access to supply fan,
filters, exhaust fan, and the heating
section. These access doors feature
double wall construction with dual
density insulation sandwiched
between 18 gauge and 20 gauge
galvanized steel panels for strength
and durability.
• Inter-Processor Communication Bridge
(IPCB) — This module provides an
amplified and filtered version of the
IPC link for connection to a Remote
Human Interface Panel. Each rooftop
that is tied into a Remote Human
Interface Panel must have a IPCB
installed into it.
• Trane Communication Interface
Module — provides interface to Trane’s
Integrated Comfort system (ICS), which
allows control and monitoring of the
rooftop by a Tracer building
management system.
• GFI Convenience Outlet (Factory
Powered) — A 15A, 115V Ground Fault
Interrupter convenience outlet shall be
factory installed. It shall be wired and
powered from a factory mounted
transformer. Unit mounted non-fused
disconnect with external handle shall
be furnished with factory powered
outlet.
• Two-Inch Spring Isolators — Supply
and exhaust fan (if applicable)
assemblies are isolated with two-inch
nominal deflection to reduce
transmission of vibrations. (Standard
feature on 90 to 130 tons.)
• VFD Line Reactors — available on all
units with Variable Frequency Drives
(VFD).
• Special Unit Paint Colors — allows
matching of HVAC equipment to
building color and sometimes
eliminates the need for expensive
barrier walls.
Field Installed Accessories
Electronic Zone Sensors
• Zone Sensors — two temperature set
point levers, heat, auto, off, or cool
system switch, fan auto or fan on
switch. Optional status indication LED
lights, System On, Heat, Cool, and
Service are available. These sensors
are used with CV units.
• Programmable Night Setback Sensors
— electronic programmable sensors
with auto or manual changeover with
seven day programming. Keyboard
selection of heat, cool, fan auto or on.
All programmable sensors have
System On, Heat, Cool, Service LED/
indicators as standard. Night setback
sensors have (1) Occupied, (1)
Unoccupied and (2) Override programs
per day. Models are available for CV
zone temperature control and VAV
supply air temperature control.
• Zone Sensor — sensor with supply air
single temperatures setpoint and
AUTO/OFF system switch. Status
indication LED lights; System On, Heat,
Cool, and Service are provided.
Sensors are available to be used with
VAV units.
• Remote Sensor — can be used for
remote zone temperature sensing
capabilities when zone sensors are
used as remote panels.
• Full Warm-Up Sensor — Morning
warm-up sensor for use with VAV
units.
• Integrated Comfort™ System sensors
— used for zone temperature sensing
when Tracer® is communicating with
the rooftop. The sensors are available
with options such as sensor only,
sensor with timed override button, and
a sensor with local temperature
adjustment control, with timed
override button.
• Remote Minimum Position
Potentiometer — Minimum position
setting of economizer can be remotely
adjusted with this accessory.
• Temperature Sensor — bullet or pencil
type sensor that could be used for
temperature input such as return air
duct temperature.
• Trane Communication Interface/
Interprocessor Communication Bridge
kit and Remote Human Interface kit —
For future sales opportunities and
flexibility of field upgrades on new
IntelliPak® rooftops after they have
been installed, two factory provided
hardware kits are available. The first kit
is an Trane Communication Interface
(TCI) module, which is required for
communication with Tracer®. Also in
this kit is an Interprocessor
Communicating Bridge (IPCB) module
which is required for communication
with an Remote Human Interface
Panel. The second kit is the Remote
Human Interface Panel, which can
control up to four rooftops. The Remote
Human Interface Panel has all the
features of the Unit Mounted Human
Interface Panel, except no service
mode interface is allowed remotely for
safety reasons. All other modules and
their required hardware are available
through our service parts organization
for field upgrades and future sales
opportunities.
Roof Curb
• Roof Curb — Curb supports the rooftop
and allows for smooth transition of
airflow from the rooftop to the
ductwork. Curb ships from stock and
ductwork can be attached directly. Two-
inch by two-inch nailer strip is also
provided, as well as gasketing to seal
supply and return openings. Curb is 14
inches high and is approved by the
National Roofing Contractors
Association.
