Address Setting
The process of establishing communication between a
receiver and sensor is referred to as association. The
following limitations apply:
• Each associated receiver/sensor set that
communicates within the reception range of the
wireless system must have a unique address.
• 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.
• To associate a receiver and sensor, the two devices
must have their rotary address switches set to the
same address.
Important: Set the addresses before applying power to
the receiver and before removing the
insulation strip (figure below) from the
sensor.

To set the receiver and sensor addresses:
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 (see the figure below).
You do not have to remove the covers to access the
rotary address switches.
Note: Do not use 000 as an address. An address of
000 returns the receiver outputs to their factory
defaults (zone temperature and setpoint
outputs: 72.5°F , removes all association
knowledge, and prevents association with a
sensor.

2. Set the three rotary address switches (locations S1, S2,
S3) on the sensor to the same address as the receiver.
Note: Do not use 000 as an address. An address of
000 removes all association knowledge, reverts
the sensor to a low-power hibernation mode,
and sends a disassociation request to the
receiver.
3. Record the address and location of the receiver and
sensor pair.
Observing Receiver for Readiness
After initial power up, the receiver conducts a channel scan
for 20 seconds. See the figure below. During this time, the
receiver selects from 16 available channels the clearest
channel on which to operate. LED1, LED2, and LED3 flash
rapidly in succession (round-robin style) while the channel
scan is in progress.
Important: Do not attempt association (leave the
insulation strip in place) until the channel
scan is finished.
