7-3-2 Parameters Description
Movement direction:
Positive movement: the output value MV will increase with the increasing of the measured
value PV, usually used for cooling control.
Negative movement: the output value MV will decrease with the increasing of the measured
value PV, usually used for heating control.
Mode setting
Common Mode:
Parameters register range: S3~S3+69, and S3~S3+7 need to be set by users;
S3+8~S3+69 are occupied by system, users can’t use them.
