HBA Function Description

HBA function detects the AC current flowing through the heater by a Current Transformer
(CT), and compares the CT input value and HBA set value. When OUT1 is ON and CT
input value is less than HBA set value during 5 seconds, AL1 is activated. Otherwise, AL1
is not activated.
The AC current flowing through heater can also be monitored in HBA setting mode.
