Progressive / Direct (Prog./Direct on the screen)
Progressive operation switches the steps sequentially one by one, based on ON-Delay
value.
Direct operation switches the biggest steps first then the other steps with a fixed delay
of 12s, to reach the target cos j faster.
The direct mode allows avoiding many useless intermediary switching.

Normal / Integral (Normal/Int. on the screen)
Normal operation: switches the steps when the demand is continuously present for the
whole switching delay time.
Integral operation: switches the steps according to averaged value of the requested
reactive power.
Integral operation is useful for applications where the load is varying rapidly.
