Control Options
Comm-3/4 Trane Communication
Interface
This factory or field-installed option shall
be provided to interface microprocessor
controlled units with the Trane Integrated
Comfort
™
systems.
Comm-5 LonTalk Communication
Interface
This factory or field-installed option shall
be provided to allow the unit to
communicate as a Trane Comm-5 device
or directly with generic LonTalk Network
Building Automation System Controls.
Zone Sensor
This field-installed control shall be
provided to interface with the Micro
equipped units and shall be available in
either manual, automatic programmable
with night setback, with system
malfunction lights, or remote sensor
options.
Thermostats
Two stage heating and cooling operation
or one stage heating and cooling shall be
available, for field installation, in either
manual or automatic changeover.
Automatic programmable electronic with
night set back shall also be available.
Differential Pressure Switches
These factory or field-installed sensors
allow individual fan failure and dirty filter
indication for microprocessor controlled
units. 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.
Reference 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. This option shall be available
for microprocessor controlled units. It can
be field-installed, or factory-installed with
the factory-installed economizer.
Differential Enthalpy Control
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. This
option shall be available for
microprocessor controlled units. It can be
field-installed, or factory-installed with the
factory-installed economizer.
Low Ambient Cooling
All microprocessor units shall have
cooling capabilities down to 18°C (0°F) as
standard.
