PropellerControl

[Fluo]

Hi all,

Can somebody help me with the following. I have a PropellerControl connected to my Profilux which controls fan speeds depending on the current temperature.
This all works very fine but I have a small issue.

I would like to have that the fans are always on, but at the lowest speed and run at higher speeds when cooling is needed.

Has anybody managed to do this? I want to do this to prevent condensation in the hood so that there is also airflow even at night.

Regards,

Bjorn

I don't think it can be done. L port do not have programmable logic...... and even if they it did have it, they would be no way to create a variable output with the programmable logic. Programmable logic can only result, in etiher "YES" or "NO", "True" or "False" or "0" or "1"

Matthias correct me if I am wrong.....

Min voltage?

Min voltage?

Couldn't you set the min voltage for the L1 port to something higher than 0? If so would that keep the fan on?

I bet you could, but if your fan is always on its going to result in higher heating costs as it will overcool at the times your tank needs heating.

I tried altering the Min voltage, but it doesn't make any difference. Probably because the PropellerControl is not instructed to swithc on.

I don't think the tank will overcool if fans are running at 3V or so, it's just to have some airflow in the hood.

this is not possible with the current firmware

Will this be made possible in a future firmware?

I was told over a year ago it would, but it still isn't.
