9. Deice Control
❋
( ); LV-B2461HL
• Deicing operation is controlled by timer and sensing the outdoor piping temperature.
• The first deicing starts only when the outdoor pipe temperature falls below -6°C after 45(30) minutes passed
• The first deicing starts only when the outdoor pipe temperature falls below -6°C after 45(30) minutes passed
from starting of heating operation.
• Deicing ends after 10(6) minutes passed from starting of deice operation or when the outdoor pipe temperature
rises over 12°C even if before 10(6) minutes.
• The second deicing starts only when the outdoor pipe temperture falls below -6°C after 45(30) minutes passed
from ending of the first deicing.
