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.
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
TM
systems.
