A heating system for a vehicle comprises a heating air fan for producing a heating
air flow to be introduced into a vehicle interior, a heating device with a heat
exchanger arrangement for heating the heating air flow delivered by the heating
air fan, a vehicle interior temperature sensor arrangement for producing an output
in connection with the temperature in the vehicle interior, a vehicle interior
reference temperature presetting arrangement, a heating air flow temperature sensor
arrangement for producing a second output in connection with the outlet temperature
of the heating air flow heated by the heating device, and also a control device
which is arranged so as to set the delivery capacity of the heating air fan in
dependence on the first output and on the vehicle interior reference temperature
predetermined by the vehicle interior reference temperature presetting arrangement,
and to set the heating capacity of the heating device in dependence on the second output.
