The manufacturer will not assume any responsibility
for equipment damage resulting from condensate
accumulation on the unit's electrical and/or mechanical
components.

Unit Clearances

The Unit Dimensions section illustrates the minimum
operating and service clearances for either a single or
multiple unit installation. These clearances are the
minimum distances necessary to assure adequate
serviceability, cataloged unit capacity, and peak
operating efficiency.
Providing less than the recommended clearances may
result in "short-circuiting" of exhaust and economizer
airflows.
Unit Description
Before shipment, each unit is leak tested, dehydrated,
charged with refrigerant and compressor oil, and run
tested for proper control operation.
The ReliaTel™ Control Module is a microelectronic
control system that is referred to as "Refrigeration
Module" (RTRM). The acronym RTRM is used
extensively throughout this document when referring
to the control system network.
This module through Proportional/Integral control
algorithms perform specific unit functions that governs
unit operation in response to; zone temperature, supply
air temperature, and/or humidity conditions depending
on the application. The stages of capacity control for
these units are achieved by starting and stopping the
compressors.
The RTRM is mounted in the control panel and is
factory wired to the respective internal components.
The RTRM receives and interprets information from
other unit modules, sensors, remote panels, and
customer binary contacts to satisfy the applicable
request for cooling.
ReliaTel™ ™ Control
Economizer Control Actuator
The ECA monitors the mixed air temperature, return air
temperature, minimum position setpoint (local or
remote), power exhaust setpoint, CO
and ambient dry bulb/enthalpy sensor or comparative
humidity (return air humidity against ambient
humidity) sensors, if selected, to control dampers to an
accuracy of +/- 5% of stroke. The actuator is spring
returned to the closed position any time that power is
lost to the unit. It is capable of delivering up to 25 inch
pounds of torque and is powered by 24 Vac.

RTCI – ReliaTel™ ™ Trane Communication
Interface (Optional)
This module is used when the application calls for an
ICS™ building management type control system. It
allows the control and monitoring of the system
through an ICS panel. The module can be ordered from
the factory or ordered as a kit to be field installed.
Follow the installation instruction that ships with each
kit when field installation is necessary.
RLCI – ReliaTel™ ™ LonTalk
Communication Interface (Optional)
This module is used when the application calls for an
ICS™ building management type control system that is
LonTalk. It allows the control and monitoring of the
system through an ICS panel. The module can be
ordered from the factory or ordered as a kit to be field
installed. Follow the installation instruction that ships
with each kit when field installation is necessary.
RBCI – ReliaTel™ ™ BACnet® ®
Communication Interface (Optional)
This module is used when the application calls for an
open BACnet protocol. It allows the control and
monitoring of the system through an ICS panel. The
module can be ordered from the factory or as a kit to be
field installed. Follow the installation instructions that
ships with each kit when field installation is necessary.
RTOM – ReliaTel™ ™ Options Module
(Optional)
The RTOM monitors the supply fan proving, clogged
filter, supply air temperature, exhaust fan setpoint,
supply air tempering, Frostat™ and smoke detector.
Refer to system input devices and functions for
operation.
Trane Air-Fi® ® Wireless Communication
Interface (Optional)
The Trane Air-Fi Wireless Communication Interface
(WCI) allows for wireless communication between
system controls, unit controls, and wireless sensors for
Trane control products that use BACnet protocol. The
WCI replaces the need for communications wire in all
system applications.
System Input Devices &
Functions
The RTRM must have a zone sensor or thermostat
input in order to operate the unit. The flexibility of
having several mode capabilities depends upon the
type of zone sensor or thermostat selected to interface
with the RTRM.
