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 se
nsor 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 33) 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 Figure 33). 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
(see Figure 33).
