Output Device Operation Check Mode
• In the output device operation check mode, the climate control unit forces all the output system actuation
devices to operate regardless of the input system. The displays change and the switch indicator lights
illuminate automatically according to the actuator operated.
• Inspect visually, listen for operation sound, and place hands over air discharge outlets to check for correct
operating conditions and to locate the malfunctioning system.
