Convenience closing/opening with recirculated air pushbutton function

Function requirements

 Circuit 15 on

 Windows normalized

 No undervoltage/overvoltage

 Function enabled via variant coding in the EIS [EZS]

 Recirculated air pushbutton actuated for t longer than
1.5 sec.

Automatic window closing via recirculated air pushbutton

The position of the windows prior to the commencement of the closing sequence is stored.

It is kept in memory until circuit 15 is switched off.

If this function is requested again during or after completion of the closing sequence, then the initially stored position is retained.

To minimize relay noise, any window that is already in the upper end stop position will not be activated.

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

Automatic window opening via recirculated air pushbutton

The function can be activated if automatic closing via the recirculated air pushbutton was performed beforehand after circuit 15 "ON".

The windows open automatically as far as the stored position if the current window position is at least 8 Hall pulses above the stored opening position.

A window will not be activated if it is positioned less than 8 Hall pulses above the stored opening position, or if it has in the meantime been lowered to below the stored position.

If automatic closing via the recirculating air pushbutton is initiated again while the window is opening, but before it has reached its stored position, the opening position initially stored will be retained in memory.

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

The automatic window closing via recirculating air pushbutton function will be aborted if

 Function requirements not satisfied

 The power window operating switch is activated in either direction

 An obstruction is detected

 There is a response from the excess force limiter (obstruction sensor)

 Zero point tolerance exceeded

The automatic window opening via recirculating air pushbutton function will be aborted if

 Function requirements not satisfied

 The power window operating switch is activated in either direction

 An obstruction is detected

 The maximum window travel is exceeded

 The window positions stored for the function of convenience closing via the recirculated air pushbutton are erased when the ignition is switched off.
