CK2002015 SAE J1939 CAN BUS air conditioning controller
CK200215 SAE J1939 is a fully-automatic climate control controller of CAN system, based on J1939 protocol. It can exchange data from the main system of the bus. In other words, it gets, analyze and process related information from the engine ECU to realize the protection of compressor clutch and stable transition of engine load. Meanwhile, it can transmit data with instrument to display the air conditioner data on the instrument display, which helps the driver to know the running information of the air conditioner.
Main function: fully-automatic control, cool, fresh air, self-checking, memory, error alarm, interior & exterior temp display, air-flow adjustment, voltage auto-protection, shift function, condenser fan 2-grade adjustment, evaporator fan PWM 7-grade adjustment.
The shift function
1)Running time check (press ventilation button for no less than 3S )
2)Air outlet temp. display (press fresh air button for no less than 3S)
3)Hold cooling (press cooling button for no less than 3S)
4)Condenser fan sensor temp.(press auto button for no less than 3S)
Application
KINGLONG Bus, YUTONG Bus
