Oki that is perfectly oki ;-)
So I've have to test it with my AE5 insted, wich I've still havent mounted on my telescope yet (yep thats right, it is going to control watercooling of my astrocamera and the fans on the telescope - as well as keeping a record of the temperture over the night).
BTW, my Aquabus on my AE4 seems dead - and since the AE4 is not on sale anymore, cant it be fixed? (Is there anyway to get a LT or something?)
