Troubleshooting
Note: When checking signal strength, both LED1 and LED3 on the receiver and sensor should
illuminate in unison if the sensor and receiver are associated. Use this feature to confirm
association. If not associated, see setup procedures in Wireless chapter. If unit still does not
work proceed in checking Receiver and sensor with testing procedures below.
2. Procedure for Testing the Receiver
• Make sure the receiver is powered.
• Set the receiver address to 000 to force the zone temperature output and zone temperature
setpoint output to their test mode values (see Table 24, p. 94).
