Diagnostics; Testing Signal Strength - Trane WTS Installation, Operation And Maintenance Manual

Diagnostics

LED1, LED2, and LED3, located on the sensor of models WTS and WZS, respond to diagnostics by
exhibiting specific blinking patterns. View their response by pressing the Test button. (See
Error codes appear on the display of the model WDS sensor when diagnostics occur. (See
Table 3. Diagnostics on the sensor
