it exceeds 5hrs, 2hrs heating time is needed.
When cooling water inlet temperature ≥ 20°C (real time value), oil heating time for first startup
is 4hrs. If power down happens when the unit is running and downtime is less than 1hrs, no
heating time delay is needed when unit restarts. If it exceeds 1hrs, 2h heating time is need. If it
exceeds 5hrs, 3hrs heating time is needed. If it exceeds 8hrs, 4hrs heating time is needed.
When cooling water inlet temperature < 20°C (real time value), oil heating time for first startup is
8hrs. If power down happens when the unit is running and downtime is less than 1hrs, no
