Mechanical Specifications
Factory or Field Installed
Options
Clogged Filter/Fan Failure Switch
A dedicated differential pressure
switch is available to achieve active
fan failure indication and/or clogged
filter indication. These indications
will be registered with either a zone
sensor with status indication lights or
an Integrated Comfort™ System.
Differential Pressure Switches
These options allow for individual
fan failure and dirty filter indication.
The fan failure switch will disable all
unit functions and "flash" the Service
LED on the zone sensor. The dirty
filter switch will light the Service LED
on the zone sensor and will allow
continued unit operation.
Discharge Air Sensing Kit
This kit provides true discharge air
sensing in heating models. This
sensor is a status indicator readable
through Tracer™ or Tracker™. The kit
is functional only with the ReliaTel
Options Module.
Economizer - Downflow
The assembly includes fully
modulating 0-100 percent motor and
dampers, barometric relief, minimum
position setting, preset linkage,
wiring harness with plug, fixed dry
bulb and spring return actuator. The
barometric relief damper shall be
standard with the downflow
economizer and shall provide a
pressure operated damper that shall
be gravity closing and shall prohibit
entrance of outside air during the
equipment "off" cycle. Solid state
enthalpy and differential enthalpy
control shall be field-installed.
Electric Heaters
Electric heat modules shall be
available for installation within the
basic unit. Electric heater elements
shall be constructed of heavy-duty
nickel chromium elements internally
delta connected for 240 volt, wye
connected for 480 and 600 volt.
Staging shall be achieved through
ReliaTel. Each heater package shall
have automatically reset high limit
control operating through heating
element contactors. All heaters shall
be individually fused from the
factory, where required, and shall
meet all NEC and CEC requirements
when properly installed. Power
assemblies shall provide single-point
connection. Electric heat modules
shall be UL listed or CSA certified. If
ordering the Through the Base
Electrical option with an Electric
Heater, the heater must be factory
installed.
Frostat
This option is to be utilized as a
safety device. The Frostat opens
when temperatures on the
evaporator coil fall below 10°F. The
temperature will need to rise to 50°F
before closing. This option should be
utilized in low airflow or high outside
air applications (Cooling Only).
LonTalk® Communications
Interface
The LonTalk communications
interface, when installed in a Voyager
unit, allows the unit to communicate
as a Tracer™ LCI-V device or directly
with generic LonTalk Network
Building Automation System
Controls.
Oversized Motors
Oversized motors shall be available
for high static applications.
Reference or Comparative
Enthalpy
Reference Enthalpy is used to
measure and communicate outdoor
humidity. The unit receives and uses
this information to provide improved
comfort cooling while using the
economizer. Comparative Enthalpy
measures and communicates
humidity for both outdoor and return
air conditions, and return air
temperature. The unit receives and
uses this information to maximize
use of economizer cooling, and to
provide maximum occupant comfort
control. Reference or Comparative
Enthalpy option shall be available
when a factory or field installed
Downflow Economizer is ordered.
This option is available on all
downflow models.
Tool-less Hail Guards
Tool-less, hail protection quality coil
guards are available for condenser
coil protection.
Trane Communication Interface
This factory or field-installed option
shall be provided to interface
ReliaTel™ controlled units with the
Trane Integrated Comfort™ systems.
Field Installed Options
CO
2
Sensing
The CO
2
sensor has the ability to
monitor space occupancy levels
within the building by measuring the
parts per million of CO
2
(Carbon
Dioxide) in the air. As the CO
2
levels
increase, the outside air damper
modulates to meet the CO
2
space
ventilation requirements.
Digital Display Zone Sensor
The Digital LCD (Liquid Crystal
Display) zone sensor has the look and
functionality of standard zone
sensors. This sensor includes a
digital display of set point
adjustment and space temperature in
F (Fahrenheit) or C (Celsius). Includes
FAN and SYSTEM buttons (supports
the service functions of the standard
sensor). E-squared memory stores
last programmed set points. Requires
24 VAC (Volts AC). This sensor should
be utilized with ReliaTel™ controls.
