40. AUXILIARY HEATING - EBERSPÄCHER

The auxiliary air heating is a separate heating

which functions entirely independent of the

vehicle. The cab temperature is measured by a

temperature sensor which is installed in the

thermostat panel (E566). This sensor sends a

signal to the electronic unit which controls the

heating.

As a result, the cab temperature automatically

remains at the preset temperature. In that case,

the blower is in continuous operation.

OPERATION OF AUXILIARY HEATING

The auxiliary air heating van be activated using

the button on thermostat E566. It is possible to

use the thermostat in combination with a

programming clock. If this button is switched to

the “interior heating” position, the heating will be

activated. A green lamp will now light up in the

thermostat.

If the heating is activated, the auxiliary heating

unit (D871) activates the fan in the heating unit

(D871).

At the same time the fuel feed pump for the

auxiliary Eberspächer heating (B122) is

activated, so that the correct amount of fuel is

fed to the ignition chamber.

If the fuel is ignited, a temperature sensor

(installed in the thermostat) will apply a voltage

to the heating unit so that at a certain

temperature, the heating unit (D871) switches

off.

If the sensor measures a lower temperature

than the temperature preset by the driver (using

the temperature control button on the

thermostat), the heating power will be adjusted.

In the case of overheating, the thermal

protection will switch off the fuel pump. This will

switch off the heating.
