Troubleshooting
Wireless Zone Sensor Failure Procedures
In the event that the UCM reports an incorrect zone Temperature/sepoint, properly inspect the
following:
Note: No special tools or software are necessary to service and test the wireless zone sensor
system. The system can be testing by using the following: 1) LEDs 1, 2, 3, and 5 on the sensor
and on the receiver; 2) The Test button (S5) on the sensor; 3) The address test mode on the
receiver; and 4) A common volt-ohm meter.
Diagnostics
Note: Reading diagnostics can show if the sensor has an issue or it has not been setup properly.
Use this information as a starting point
• LED1, LED2, and LED3 will respond to diagnostics by exhibiting specific blinking patterns. They
will occur on the sensor as a result of pressing the Test button (S5) (
Table 18, p. 65 ). They will
occur on the receiver independently of any user action ( Table 18, p. 65 ).
