The WARNING functions can be set to Enable or Disable. Set to "ENABLE" when using the

A setting value of the "Pump Run Time Over" and "Pump Overload" are adjustable. The WARNING
detection can be released by setting the value larger than pump running hours after "Pump Run Time
Over" is detected. Also, the WARNING detection can be released by powering off the pump after
"Pump Overload" is detected.
