Camera Windshield Defrost Heater

The camera windshield defrost heater keeps the windshield in front of the IPMA  clear of frost and ice. The IPMA  uses input from the front camera and the ambient air temperature to turn the camera windshield defrost heater on and off. Voltage and ground is supplied to the heater by the IPMA  . The heater may be commanded on if the ambient temperature is below 5°C (41°F).
