BAS-SVX04A-EN • Wireless Zone Sensor 41
Operation, Maintenance, and Troubleshooting
Receiver Power-up Sequence
When power is applied to the receiver, the following sequences occur. They are
dependent on the rotary switch address setting and on the association status of
the receiver.
Address set to 000 and receiver is not associated with a sensor
• LED5 is constantly On, indicating power is applied and the receiver is
functional.
• Zone temperature and setpoint outputs default to 72.5°F (22.5°C) indefinitely
(
Tab l e 9, p. 39).
• Status LED3 will display a 2-blink pattern diagnostic (Tab l e 6, p. 33).
Address set from 001 to 999 and receiver is not associated with a sensor
• LED5 is constantly On, indicating power is applied and the receiver is
functional.
• Zone temperature and setpoint outputs default to 72.5°F (22.5°C).
• The receiver conducts an energy scan for 10 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 (
“Receiver Indicates Readiness to Associate,” p. 25).
Address set from 001 to 999 (and not changed since most recent power-
up) and receiver is associated with a sensor
• LED5 is constantly On, indicating power is applied and the receiver is
functional.
• Zone temperature and setpoint outputs default to 72.5°F (22.5°C).
• 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 (
Tab l e 9, p. 39).
