1.5.6. Autonomous heater and fan

Autonomous отопителъ / the fan can work in the mode warmly – and refrigerating capacities is autonomous from the engine.
The autonomous heater works in combination with the conditioner irrespective of the engine. The principle of its work is based on fuel combustion. It is intended first of all for warming up of salon and facilitates thawing of glasses.
The autonomous heater can be used as an additional heater both at the switched-off engine, and at the movement (for example, at a stage of warming up of the engine).
The independent fan also works irrespective of the engine and effectively promotes decrease in temperature in interior of the car left in the sun.
Management of the mode of autonomous heating / ventilation is carried out by means of indication of a combination of devices. Through the menu it is possible to program time and duration of inclusion. Duration of work of an autonomous heater / fan can fluctuate ranging from 15 up to 60 min. The autonomous heater / fan can be switched on and off also remote radio control.
At the programmed timer and at inclusion by means of remote radio control the operating mode (an autonomous heater or the fan) decides on the basis of comparison of the system of heating/ventilation or the conditioner of temperature installed by appropriate authorities of management on the actual temperature in salon.

Work of an autonomous heater in the closed spaces is not allowed.
Work of an autonomous heater is not allowed during filling of the car with fuel.
Work of an autonomous heater is followed by high-temperature emission of the fulfilled gases. Therefore at the parking of the car you monitor providing a free exit of the hot fulfilled gases from the lower party of a casing of the engine and lack of direct contact of the fulfilled gases with flammable materials.

If fuel level in a tank reached the reserve field, then the autonomous heater cannot be included.
The autonomous heater / fan is disconnected at the slabozaryazhenny accumulator at once. For safety of the accumulator do not use several times in a row continuously autonomous heater.
Operation of an autonomous heater / fan does not demand special setup of the conditioner. However it is recommended to open deflectors.
At operation of the car on RME fuel (the diesel engine) operation of an autonomous heater is not allowed.

For acceleration of cooling of an autonomous heater after each its switching off some time the circulation pulser and the fan giving hot air continue to work.
At a low external temperature in a zone of a motor compartment formation of water vapor is possible. This normal physical phenomenon and therefore should not be the cause for alarm.
