is damaged, it must be replaced with the new centralized
controller, it is required to be initialized, and it is the same
case for control main board.
If the controller or main board in one control system
It is required to adopt the specified cable for
power supply. Please do not share the power with

breaker suited with the working pressure of
controller. Please do not use the wire or fuse
beyond the specified grade.
YORK-003 control board and shell of
transformer must be connected with the ground
wire. Please do not connect the ground wire with
the fuel gas pipe, water pipe, or lightning
