Zone Sensors — The building
occupant's comfort control devices.
They replace the conventional electro-
mechanical thermostats. Zone
sensors are to be used with the
Voyager units with the Micro control.
These sensors are available in the
following options:
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.

TM
Integrated Comfort System —
Sensor(s) available with optional
temperature
adjustment and
override buttons
to provide
central control
through a Trane
Integrated
TM
Comfort
system.
Economizer Controls — The
standard equipment offering is a fixed
dry bulb changeover control. In
addition to the standard offering, there
are two other field-installed control
accessories.
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 plus energy savings potential
than the standard dry bulb control due
to the additional wet bulb sensing
capability.
63
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 avail-
able.
Remote Potentiometer — Minimum
position setting of economizer can be
remotely adjusted with this accessory.
Trane Communication Interface
(TCI) — This factory or field-installed
micro-processor interface allows the
unit to communicate to Trane's
Integrated Comfort TM system.
Conventional Thermostat Interface
(CTI) — This field installed option will
allow the Micro units to interface with
most conventional electro-mechanical
thermostats.
Differential Pressure Switches —
This 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.
Input / Output Expansion Acces-
sory — This kit allows Integrated
Comfort TM Sytems to read Supply Air
Temperature, Return Air Temperature,
Return Air Humidity, and direct
indication of fan failure without the use
of an economizer or motorized outside
air accessory.
Electronic Time Clock — This field
installed accessory allows up to 4
units night set-back and unoccupied
functions when using a standard (Dual
Setpoint) zone sensor module.
