Thanks for explanation... the reason I suppose in the message... but, admiting the utility and the plus of security of this measure, maybe some users (I, for example) have some very noisy fans, that make this service when needed, but not in the startup.
Even if the fans are some lazy in lowers power output levels, we can put in Aquaero a mininum power output that solves this problems

(and solves and make more stable regulations too)
Thanks again
