Stop ventilation function

Function up to 31.5.01

Ventilation mode is ended manually by pressing the switch. It is also stopped automatically by the:

 Left front seat adjustment control module, with memory (N32/1)

 Right front seat adjustment control module, with memory (N32/2)

 Rear seat control module (N25/6, MODEL 220 only)

if:

 circuit 15R OFF has been detected
(timer control runs for a further 5 min if circuit 15C is still ON), or

 undervoltage/overvoltage has been detected
(if the value has dropped below the undervoltage/overvoltage threshold for convenience functions, the seat ventilation switches off, the LEDs continue to be lit)

-----------------------------------------------------------------------------------------

Up to 31.5.01

The ventilation mode is, if there are no faults present,

started at "stage 3", automatically switched down to "stage 2" after 10 min and after a further 10 min to "stage 1".

It is possible at any time to switch off or switch over the seat ventilation to another ventilation stage by operating the switch.

 The heated seats can also be adjusted, from the park position individually for the passenger and individual rear seat, from the right rear compartment (left hand drive vehicles) via the selection switch between rear and front seat adjustment on right (N69/4s9) (left hand drive vehicles).

As of 1.6.01

The timer control for ventilation mode of the front seats and rear seats is discontinued.

The selected ventilation stage (I, II, III) of the seat ventilation remains on and is not automatically switched back.

It is possible at any time to switch off or switch the seat ventilation to another ventilation stage by operating the switch.

As of 1.9.02

The seat control module implements a timer control for the seat ventilation. After switching on "stage 3", this remains switched on for t = 10 min. Then the system automatically switches to
"stage 2", which remains switched on for t = 10 min. Then it switches automatically to "stage 1".

The parameters for the times of the 3 ventilation stages can be set via diagnosis in the seat control module. The timer control can be switched on and off via diagnosis in the seat control module.

 In the vehicle as-delivered state, the timer control for the ventilation stages is switched off.

 Provided "circuit 15C ON", the timer control continues to run for
t = 5 min, if "circuit 15R OFF" or the voltage is too low/too high.
