Manual Association; Disassociation; Sensor/Receiver Compatibility; Receiver - Trane BCHE Installation, Operation And Maintenance Manual

Notes:
• If lithium batteries are temporarily unavailable,
alkaline batteries can be used. However,
alkaline battery life is very short by comparison.
• The battery life for model WDS may decrease
with extended LCD display activity.
Battery Installation
WARNING
Risk of Injury with Batteries!
Failure to follow handling instructions below could
result in severe injury.
• Do NOT install batteries backwards.
• Do NOT disassemble, charge, or expose
batteries to water, fire, or high temperature.
• Keep batteries away from children. If swallowed,
contact your local poison control center
immediately.
1. Observe the polarity indicators that are molded into the
cover.
2. Install two batteries (of the type specified in
Type," p. 128) in the battery-holding slot that is molded
into the sensor cover.
The sensor has been designed to prevent damage if the
batteries are installed backwards, to reduce the potential
for injury.

Manual Association

Before attempting manual or automatic association, the
receiver must indicate readiness to associate (one blink
pattern of LED3 on receiver). Refer to ",".
At any time, the manual association method can be used to
associate the receiver with the sensor. If an association
was previously established between a receiver and a
sensor and needs to be re-established, the manual
association process may be used. If an association has not
yet been established, the automatic association process is
recommended (see "Associating Sensor to Receiver," p.
75).
1. Using a small screwdriver, set the three rotary address
switches (locations S1, S2, S3) on the receiver to an
address between 001 and 999.
Note: An address can be changed at any time after
initial association has been established. It is not
necessary to power down the receiver or sensor.
2. Set the three rotary address switches ( locations S1,
S2, S3) on the sensor to the same address as the

receiver.

3. Record the address and location of the receiver and
sensor pair.

4. After verifying that the receiver and sensor are powered
up, press the Test button on the sensor to establish that

adequate for proper functioning.

Disassociation

The receiver disassociates from the sensor (by removing
all stored association information), conducts a channel
scan, and restarts itself, if any of the following are true:
• The receiver address is changed from its current
setting (001–999)
• The receiver receives a disassociation notification from
its associated sensor
• The receiver does not receive a communication from its
associated sensor within 50 minutes.
• The sensor and receiver are associated and
communicating at the time the sensor is set to 000 and
the Test button is pressed.
Note: A disassociated sensor will transit an association

Sensor/Receiver Compatibility

Version 1.5 and higher receivers are compatible with all
"Battery
sensors models and support all functions. Receivers
released prior to version 1.5 are compatible with only
model WZS.
Replacing a Failed Sensor or Receiver
Note: Receivers ship installed on the unit. To remove the
To replace a failed sensor or receiver:
1. Confirm that the device is disassociated (see
p. 126
2. Set the rotary address switch of the new device to
match the address of the remaining sensor or receiver.
Note: There is no need to remove power from the
3. Apply power to the new device. Association between
the new and the remaining devices will automatically
occur.
Note: When replacing a WDS sensor, the receiver (version

has not been placed into configuration mode and the
factory default configuration is still valid. If the
