Information

Checks if the ySet value is legal by checking if the device can either be turned on or off, depending on which state it was in.

The output yOut equals ySet, if the device

• is on and ySet is greater than ySet_small
• or is off and ySet is 0
• or is on and should turn off, and exceeds the minimal on-time (if active)
• or is off and should turn on, and does neither exceed the maximal cycle rate (if active) nor violates the minimal off-time (if active).

If the device is on and should turn off, but does not exceed the minimal on-time (if active), yOut equals min(ySet, ySetMin).

If the device is off and should turn on, but exceeds the maximal cycle rate (if active) or violates the minimal off-time (if active), yOut equals 0.
