AIR-SS-2 Testing

How to test the AIR-SS2 Snow Owl.

Connect the voltmeter across the black and red leads from the sensor (low-voltage wiring terminals at the control). Connect the black test lead to the black wire. A reading of 23 to 28 VDC should be present. Now, check the reading across the black and white sensor leads. A reading of 22 to 28 VDC should be observed with a warm (above 38°F) and dry sensor. Both the SNOW LED and HEAT LED should remain off.  Cool the temperature probe of the sensor with the Freeze Spray. Frost should form on the temperature probe. Alternately, place the temperature probe in ice water. The SNOW LED and HEAT LED should remain off.

Use water, or moisten a finger and touch the moisture sensing grid on top of the sensor. Both the SNOW LED and HEAT LED should come on and the voltage between the white and black sensor leads should be less than 2 VDC.
