Unit of the fan control

The unit of the fan control on the basis of a signal from gauges of the radiator fan control adjusts the radiator fan, the condenser fan and central air.

Electric circuit of fan control

1 – switch VD/ND 2 – gauge of radiator fan control 3 – electric motor of the condenser fan 4 – electric motor of the radiator fan 5 – main relay of the radiator fan 6 – relay of the radiator fan 7 – average pressure switch

If the temperature of a cooling liquid of the engine reaches approximately 84°С, the unit of fan control closes Trl and compels to rotate in the slow speed fans of the radiator and condenser.

If the temperature of a cooling liquid of the engine reaches approximately 90°С, the unit of fan control closes Tr2 and compels to rotate in the fast speed fans of the radiator and condenser.

If the temperature of a cooling liquid of the engine reaches approximately 109°С, the unit of the fan control results TrЗ in OFF (switched off) and the compressor of the conditioner compels to stop.
