With this logic group, the fan stages 0, 1, 2 and 3 can be switched through via a 1-bit telegram.

After initialisation of the logic group, the output value is always increased by 1 with each telegram via the "trigger input", regardless of the telegram value.

When the value 3 is reached, the output value is set back to 0 and increased again by the value 1.

The value 0 is set by the translator tool placed after the addition.
