External air for heating is sucked in through soaking up lattice of the case of the air filter which is under a windscreen, and the fan moves in car salon. Thus air passes through a heater box, and therefrom through separate nozzles arrives in salon.

Management of air stream is carried out заслонками, cables set in motion. If the heater is established in a mode “warm” ("warmly"), air stream goes through a radiator. The radiator is in a box of a heater and is warmed with a hot cooling liquid.

The passing stream of air heats up as a result of contact with plates of a radiator and arrives in salon. Thermal productivity is regulated by a stream of a cooling liquid for what the system has two electromagnetic valves in a contour of system of cooling.

Regulation of temperature of air is carried out by the rotary handle, separately for the right and left half of salon. The electronic device in the management block operates time of opening of cranes of a heater depending on temperature in salon. The temperature gauge is located behind a heater box. Thanks to electronic regulation air temperature is supported close to a constant, irrespective of speed of the car and external temperature.

For strengthening of a thermal stream the heating fan having smooth regulation serves.
