To test this circuit, place a DC milliamp meter in series with either of the leads to the humidity sensor. If the reading is 0ma, polarity may be reversed. Reverse + & - and retest. If the reading does not correspond to the table below, check the output voltage from the ECA with the sensor disconnected. It should be approximately 20VDC. If so, and all connections are intact, replace the sensor. If 20VDC is not present, yet the ECA green LED is on, the ECA module has failed.Humidity sensor accuracy : +/-10% RH.
