CONTROL SYSTEM OAT – Outdoor Air Temperature TLD – Time from Last Deicing DI – Deicing Interval (Time Interval between Two Deicing) DST – Deicing static threshold (Temperature) Deicing interval time when compressor is first started in heat mode, is 10 minutes if OCT < -2, and is 40 minutes in other cases. Deicing interval time is changed (increased/ decreased in 10 minutes steps) as a function of deicing time. If deicing time is shorter then former deicing time, the deicing interval time will be increased.
