Product Description
This manual contains information about installing, operating, and maintaining
the Trane
Overview
The Trane Wireless Zone Sensor set includes a sensor and a receiver that work
together to provide the same functions as the equivalent Trane wired sensor
(#4190-1090), such as the standard 10 kΩ temperature input (with the exception of
the communication jack). No further software or hardware is necessary for site
evaluation, installation, or maintenance.
The sensor transmits the zone temperature, all zone temperature setpoint
functions, timed override Occupied (On) and timed override Unoccupied (Cancel)
information to the receiver. The receiver electrically reproduces the zone
temperature resistance, all zone temperature setpoint function resistances, and
timed override On and timed override Cancel information as sent by the sensor.
Factory or Field Installed
The information in this manual is applicable to Wireless Zone Sensor sets that
are either factory or field installed.

Setting the Address, Mounting, Wiring,
and Associating the Receiver and
Sensor
The following procedure list shows the recommended order for installation:
• Choosing a location for mounting the receiver and sensor
• Setting the rotary switches on the receiver and the sensor
• Mounting the base plate of the receiver
• Wiring the receiver to the unit controller
• Replacing and securing the receiver cover
• Applying power to the receiver
• Powering the sensor and associating the sensor to the receiver
• Testing signal and battery strength
• Automatic association
• Manual association
• Mounting the base plate of the sensor
• Replacing and securing the sensor cover
Choosing a Location for Mounting the Receiver and Sensor
Placement of the receiver and the sensor set is critical to proper operation. In
most installations, distance is not the limiting factor for proper radio signal
quality. It is more greatly affected by walls, barriers, and general clutter. For best
radio transmission range and reliability, wherever possible, mount the receiver
and sensor in line of sight. Try to minimize the number of barriers between the
pair of devices. In general, sheetrock walls and ceiling tiles offer little restriction
to the propagation of the radio signal throughout the building; concrete or metal
barriers offer the most restriction.
The transmission range for the sensor is as follows:
• Open range: 2,500 ft (762 m) (packet error rate = 2%)
• Usable range: 200 ft (61 m)
• Typical range: 75 ft (23 m)
Location Considerations for the Receiver
When selecting a location for the receiver, consider both ambient and radio
transmission characteristics of the location.
Ambient considerations
• Avoid locations that are outside the operating temperature and humidity
range (refer to
BAS-SVX04A-EN • Wireless Zone Sensor 13
Ta bl e 11, p . 45).
Setting the Address, Mounting, Wiring, and Associating the
Receiver and Sensor
Radio transmission considerations
• Avoid metal barriers between the receiver and the sensor; they decrease
radio signal quality significantly (for example, plastered walls with metal
lathe or metal roof decks).
• Avoid placing the receiver inside metal enclosures.
• Avoid radio transmissions through thick, solid concrete walls.
• Conduct rooftop mounting and operation of the receiver only after careful
site evaluation and confirmation.
Location Considerations for the Sensor
When selecting a location for the sensor, consider both thermal and radio
transmission characteristics of the location.
Thermal considerations
• Avoid areas of direct sunlight.
• Avoid areas in the direct airstream of air diffusers.
• Avoid exterior walls and other walls that have a temperature differential
between their two sides.
• Avoid areas close to sources of heat such as sunlight, appliances, or other
equipment.
• Avoid drafty areas.
• Avoid dead spots behind doors, projection screens, or corners.
Radio transmission considerations
• Avoid metal barriers between the sensor and receiver, such as plastered walls
with metal lathe. They will decrease radio signal quality.
• Avoid placing the sensor inside metal enclosures.
• Avoid radio transmissions through thick, solid concrete walls.

Receiver and Sensor
Setting the Rotary Address Switches on the Receiver and the Sensor
Note: To expedite the installation and association process, set the addresses
before applying power to the receiver.
The process of establishing communication between the receiver and sensor is
referred to as association. The receiver and the sensor must have their rotary
switches set to the same address in order to enable communication between the
two devices (see Figure 3). Important limitations are as follows:
• Only one associated receiver/sensor set can communicate within the
reception range of the wireless system.
• It is not possible to associate more than one sensor to a receiver, nor is it
possible to associate more than one receiver to a sensor.
