Cooldown Test
This test has been designed for performance testing of the A/C system at the manufacturing facility. If the HVAC control module is replaced, the
Cooldown test will occur during Calibration test. Cooldown will not occur on Heater Only units. During the Cooldown test the control will monitor the
temperature of the Fin Sensor. The A/C system must be able to bring the evaporator temperature down a predetermined minimum amount in less than
2 minutes.
