- In basic setting (as-delivered condition), auxiliary heater runs until set program time has elapsed

or until manual shut-off.

Notes:

Voltage at terminal 58s and thus brightness of -E111 button illumination are governed by illumination control setting.
Voltage at terminal 58d is generated as square-wave signal by dash panel insert. Brightness of -E111 display is determined by actuation time. Measuring instrument shows mean value.
Terminal 58d actuation time depends on setting of illumination control and brightness level determined by photosensor in dash panel insert.

Notes:

When switch -E255 is open (flap closed, pre-selection clock not visible), illumination of pre-selection clock is switched off and operation of pre-selection clock -E111 is also restricted.
The first 1000 vehicles with auxiliary heater were fitted with a pre-selection clock -E111 (part no. index A), on which all operating functions are deactivated when switch -E255 is open.

In the case of pre-selection clocks (as of part no. index C), auxiliary ventilation/auxiliary heating can also be switched on and off with switch -E255 open by pressing buttons -B- and -C- (emergency operation if switch defective).

Notes:

Warning lamp shows operating status of pre-selection clock/auxiliary heater:

- Warning lamp off = auxiliary heater off, cut-in time not activated

- Warning lamp flashes = cut-in time activated in pre-selection clock -E111

- Warning lamp lights = auxiliary heater on (auxiliary heating or auxiliary ventilation mode)

Warning lamp is actuated with pre-selection clock -E111 flap closed and open.
Warning lamp does not light if positive and negative are interchanged (LED).

Note:

If earth is applied to connector B contact 5 (via pre-selection clock -E111), air conditioning system operating and display unit -E87/control unit -J214 (in heater control) and fresh-air blower -V2 are switched on, but auxiliary heater does not start up (auxiliary ventilation mode).

Notes:

If earth is applied to connector contact 3 (via pre-selection clock -E111), air conditioning system operating and display unit -E87/control unit -J214 (in heater control) and fresh-air blower -V2 are switched on, but auxiliary heater does not start up (auxiliary ventilation mode).
At low coolant temperatures (less than 30 °C),operating and display unit -E87, control unit -J214 and fresh-air blower -V2 are not actuated in auxiliary heating mode until coolant temperature has exceeded 30 °C.

Notes:

"Auxiliary heating" or "auxiliary ventilation" mode is determined by setting on pre-selection clock -E111 and cannot be altered with remote control.
2 different settings can be made on pre-selection clock -E111 (=> Page
82-32
, setting pre-selection clock -E111):

- In basic setting (as-delivered condition, setting "T60"), pre-selection clock recognises by way of positive signal (from

auxiliary heating radio controlled receiver -R64) at contact 7, that auxiliary heater is to be switched on. Switch off takes place

immediately if positive signal is no longer applied.

- In modified basic setting (setting "T62"), pre-selection clock expects a data telegram (square-wave

signals). In this setting, it is therefore not possible to switch on auxiliary heater via remote control.

Auxiliary heating/auxiliary ventilation time is determined by remote control on activation (cut-in signal contains a time module). This time module is permanently stored in the remote control and cannot be altered. There are different versions for vehicles with and without pre-selection clock.

=> Parts List

Lamp on remote control starts to flash when "START" button is pressed. By way of a check, this lamp flashes:
In the case of the version with 30 min. operating time (for vehicles with pre-selection clock) until auxiliary heating/auxiliary ventilation is switched off by pressing "OFF" button or until 30 min. running time has elapsed
In the case of the version with 60 min. operating time (for vehicles with no pre-selection clock) for approx. 30 s after pressing "START" button
The remote control is a transmitter. Switch-on and switch-off of auxiliary heating/auxiliary ventilation via pre-selection clock -E111 (or dash panel insert) is thus not recognised.
