Circular switching increases the lifetime of capacitors and contactors by balancing the stress among all the outputs.
In case of "double first step" (1:1:2:2:..., 1:1:2:4:4.,...), the circularity applies to the first two outputs and also on the
outputs of higher value.

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
 faster.
The direct mode allows avoiding many useless intermediary switching.
