Floor / Defroster Air Distribution, Residual Heater (ECC)

This only applies to cars with electronic climate control (climate control with temperature display) and an electric water pump or parking heater.

This function is used to change the distribution of air between the floor and defroster when the residual heater is running.

Available parameters:

• 90/10 (90% floor, 10% defroster)
• 80/20 (80% floor, 20% defroster)
• 70/30 (70% floor, 30% defroster)
• 60/40 (60% floor, 40% defroster)
• 50/50 (50% floor, 50% defroster)
• 30/70 (30% floor, 70% defroster)
• 10/90 (10% floor, 90% defroster).

The air distribution between the floor and defroster for the residual heater is programmed via the vehicle communication socket under function group 8, Climate control (climate control module (CCM)), Programming the climate control module (CCM).
