HVAC Tester

HVAC Tester

HVAC (Heating, ventilation, and air conditioning) tester is designed for testing climate control devices in cars.

It usually consist of 3 encoders – 2 temperature encoders due to 2 zones and fan intensity. To test the functionality, we need to rotate with the encoders, read communication signals (via LIN or CAN) , push the knobs and measure the intensity of LED background.
