CK200203 automatic a/c controller applies to internal climate control for bus with sub-engine. It will control the starting, preheating , air conditioner starting up, and cooling of the sub-engine automatically
Main functions:Auto control; Cooling, Fresh air, Power-lost memory, Error alarm, Interior & Exterior temp. display, Auto voltage protection, Shift function
The shift function
1)Defrost temp. display (press fresh air button for no less than 3S)
2)Hold cooling (press cool button for no less 3S)
Application
YUTONG bus air condition
