Replacing Sensor Batteries (Wireless Controls)
Sensor battery type, length of life, and installation are
addressed in this section.
Battery Type (Wireless Controls)
NOTICE:
Equipment Damage!
The batteries are manufactured in a ready-to-use state.
They are not designed for recharging. Recharging can
cause battery leakage or, in some cases, can cause the
safety release vent to open.
NOTICE:
Equipment Damage!
Do not attempt to hook up the sensor to a power
supply. Equipment damage may result.
Use two non-rechargeable 1.5 V lithium AA batteries in the
sensor. To maintain UL rating, use only UL-listed lithium
batteries. The sensor ships with Energizer
already installed. Replacement batteries are available at
Trane Service Parts Centers (p/n X13770035010) or other
local suppliers.
Battery Life (Wireless Controls)
Battery life is five years under normal conditions. If the
sensor is not used for an extended period of time, do one
of the following:
• Set the sensor address to 000 to place the sensor into
a low-power hibernation mode.
• Remove the batteries
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 a model WDS may decrease with
extended LCD display activity.

WARNING
Prevent Injury!
Batteries can explode or leak and cause burns if
installed backwards, disassembled, charged, or
exposed to water, fire, or high temperature.

The sensor has been designed to prevent damage if the
batteries are installed backwards, to reduce the potential
for injury.
Manual Association (Wireless Controls)
Before attempting manual or automatic association, the
receiver must indicate readiness to associate (one blink
pattern of LED3 on receiver). Refer to
Receiver for Readiness to Associate, " p.
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
