Fig. 2.50. Assembly diagram of control of the cooling system fan

Unlike the previous system of electric fans, the sensor switch of temperature of cooling liquid was removed. Instead for control of the electric motor of the fan the sensor of temperature of cooling liquid is used that simplified system. The control system of the fan of the cooling system includes/switches off 3 relays of the fan according to temperature of cooling liquid and an operating mode of the air conditioning system. When fans are switched on, two electric motors of fans can work on low (consistently) or high (parallel to) speed.
