the type of operation, direct/reverse setting, event main setting, event sub-setting,
hysteresis settings, etc.
Note
• For the meaning of U (unit), see the terminology list in the Appendix.
Operation type Setting Direct action
: ON/OFF changes at the value
: ON/OFF changes when the value is exceeded
Reverse action

During an SP ramp: the operation is different in that the
final SP is used instead of the present SP.
