8301-090 Outdoor Temperature/Humidity Sensor
Troubleshooting the temperature/humidity sensor is necessary if the temperature or humidity reading is inaccurate.
Always start sensor troubleshooting by verifying connections at the sensor board and at the LC6000 terminal blocks.
Improper connection will cause inaccurate readings. Next, verify continuity at both ends of wires running between
the sensor and the LC6000. A severed or damaged wire will cause inaccurate readings. As a last step, verify voltage
and resistance at the sensor and the LC6000 terminal block per the provided table. If the sensor is found to be
malfunctioning, replace the sensor.
