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

Auto or manual changeover with seven-
day programming. Keyboard selection of
Heat, Cool, Fan, Auto, or On. All
programmable sensors have System On,

Humidity Sensor
Field installed, wall-mounted or duct-
mounted humidity sensor is used to
control activation of the hot gas reheat
dehumidification
option. The
humidity sensor
can be set for
humidity levels
between 40% and
60% relative

CO
2
Sensing
The CO
2
sensor shall have 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
accessory shall be available as
field installed.
