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.

Programmable Night Setback

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
one (1) Occupied, one (1) Un-occupied,
and two (2) Override programs per day.

Integrated

System

Sensor(s)
available with
optional
temperature
adjustment and
override buttons
to provide central
control through a
Trane Integrated

TM

 system.

Field Installed Control Options

Zone Sensors

Zone sensors are the building occupant’s
comfort control devices. They replace the
conventional electro-mechanical
thermostats. The following zone sensor
options are available for Voyager units
with the ReliaTel™ control:

Manual Changeover

Heat, Cool or Off
System Switch. Fan
Auto or Off Switch.
One temperature
setpoint lever.

Manual/Automatic Changeover

Auto, Heat, Cool or Off System Switch.
Fan Auto or Off
Switch. Two
temperature
setpoint levers.
Optional Status
Indication LED lights,
System On, Heat,
Cool, or Service.

Remote Sensor

Sensor(s) available for all zone sensors to
provide remote
sensing
capabilities.

Dual Thermistor Remote Zone Sensor

This sensor will allow the customer to
reduce the total number of remote
sensors to obtain space temperature
averaging.  This sensor should be utilized
with ReliaTel controls.

CO

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. The CO

2

 sensor

kit is available as a field installed
accessory.

Economizer Controls

The standard equipment offering is a
fixed dry bulb changeover control. In
addition, there are two optional controls,
Enthalpy and Differential Enthalpy
Control.

Enthalpy Control

Replaces the dry bulb control with a wet
bulb changeover controller which has  a
fully adjustable set point. Enthalpy control
offers a higher level of comfort control,
along with energy savings potential, than
the standard dry bulb control.  This is due
to the additional wet bulb sensing
capability.

Differential Enthalpy

Replaces the standard dry bulb control
with two enthalpy sensors that compare
total heat content of the indoor air and
outdoor air to determine the most
efficient air source. This control option
offers the highest level of comfort control,
plus energy efficiency, available.

Remote Potentiometer

Minimum position setting of economizer
can be remotely adjusted with this
accessory.

Differential Pressure Switches

This factory or field-installed option
allows 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.

Trane Communication Interface (TCI)

This factory or field-installed micro-
processor interface allows the unit to
communicate to Trane’s Integrated
Comfort

TM

 system.
