The regulations for both fans are identical, therefore there is only one regulation ramp which
is brought to a single analogue output. You will be required to set the position from the
Constructor Menu by going to parameter HA07. If HA07=0 the signal will not be enabled on
any anlalogue output.
6.5.3 Modulating regulation with steps to enable
The same logic for the modulating regulation applies with the additional possibility of
shutting down the fan with a specific step on the regulation ramp. For this regulation select
PF01=3.
The shutdown point corresponds to the value of the ambient temperature regulation Set Point.
The action of strarting up and and shutting down is delayed in order to avoid short cycles and
having the transistors potentiallly mislead the regulation (parameter PF09).
