Operation

Receiver Power-up Sequence

When power is applied to the receiver, one of the following sequences occurs. The sequence is
dependent on the address setting and the association status of the receiver.
Address set to 000 and receiver is not associated with a sensor
•
•
•
Address set from 001 to 999 and receiver is not associated with a sensor
•
•
•
•
Address set from 001 to 999 (and not changed since most recent power-up)
and receiver is associated with a sensor
•
•
•
•
Note: Once a receiver communicates to a WTS sensor, the receiver disables (opens) its zone

LED5 is constantly On, indicating power is applied and the receiver is functional.
All models: Zone temperature and cooling setpoint default to 72.5°F (22.5°C). 
WDS only: The heating setpoint defaults to 70.5°F (21.4°C) and the fan/system output will be

The receiver conducts an energy scan for 20 seconds to determine the clearest channel on
which to operate.
LED3 flashes On every 2 seconds when it is ready to accept a sensor association request.
When an association request is made by a sensor, the receiver instructs the sensor on which
power level to operate. Then the receiver and sensor begin operation at the appropriate
channel and power level (see

Zone temperature and setpoint default to 72.5°F (22.5°C). WDS only: Heating setpoint defaults
to 70.5°F (21.4°C), Fan = Auto, System = Off.
The receiver waits for a broadcast transmission from its associated sensor. When a
transmission is received, the receiver positions its zone temperature and setpoint outputs
appropriately.
If the receiver does not receive a communicated signal from its associated sensor within 35
minutes, zone temperature and setpoint outputs fail, generating a unit controller alarm (see
"Output Values—Failure and Default Modes of Operation" p.
