●Band width, Temperature upper/lower limit width

Temperature range for outputting alarms etc., when PV deviates by more than a fixed temperature from the set temperature (SV).

●Breaker

A device which protects load circuits and wires by breaking the circuit when an abnormal current flows in an outlet circuit due to problems such as overload or shorting. Depending on the application, a breaker may be called a motor breaker, circuit protector or other names. Ground fault circuit interrupters monitor both current in the main circuit and leakage current, and break the circuit if leakage current is too high.
