System Operation
Electric Booster Heater
In diesel vehicles which give off little residual heat,
a booster heater is used to heat the passenger
compartment rapidly in the case of low ambient
temperatures.
If the interior temperature has been set to HI, or if
the heater controls have been switched to the
highest setting, the two-zone air conditioning
system sends an "electric booster heater ON"
request signal to the CAN (controller area network)
via the medium speed GEM bus. If a manual air
conditioning system is installed, the signal is
transmitted via a conventional cable connection.
The GEM switches on the electric booster heater
depending on the following parameters:
• Engine coolant temperature is below 60 °C.
• Ambient air temperature is below 10 °C.
• Sufficient generator capacity is available.
The electric booster heater electronics activate
three output stages as a function of a pulse width
modulated signal PWM (pulse width modulation)
generated by the GEM. The output stages switch
the three heating elements of the electric booster
heater ON or OFF individually, whereby the heating
periods of the individual elements can overlap. Due
to the variable switch-on duration, continuously
variable temperature control is possible. The overall
heating power of the three heating elements is
linearly proportional to the PWM signal. If the PWM
signal is below 10% or above 95%, the electric
booster heater is not activated.
The electric booster heater is switched off when
an engine coolant temperature of 70°C or an
ambient air temperature of 20°C is exceeded.
