DC Fan config in Artisan with TC4+

Hi,
I'm planning a home roaster leveraging on the latest version of TC4+ and Artisan.
I had searched through web and found several useful guides, but I still have one question on the DC Fan configuration in Artisan using TC4+.
Question:
Do I use IO3 in the configuration if I use the TC4+ onboard DC (2-wire) outputs? Is the following correct?
Event dialog box
Sliders tab/section
Action: Serial Command
Command: IO3;{}
Does this mean IO3 is used for both AC as well a DC on TC4+, as there are separate headers for IO3 on the TC4+ shield?
In addition, I intend to connect a DC input of 24V 2A into the TC4+, to power the DC Fan

While you may get a response here for technical questions, also consider the Artisan Community mailing list.

Thanks!
I'd check out that community.

Update:
I tested and the serial command I posted earlier worked.

Congrats. I use the same command. My DC fan was configured with a mosfet controlled by IO3. I say "was" because after some 500 roasts the plastic fan blades disintegrated and I went back to my old and noisier AC fan controlled by OT1. I placed it much further away from the heat so it should do fine. But I wish to replace my DC fan to have a backup. Which fan did you choose? Does it have PWM capability or did you require a MOSFET or some such?hannson wrote:Thanks!

DC Fan with plastic blades. DC motor rated at 20v.chuckcoffee wrote:hannson
What fan are you using?

I'm using DC Fan with plastic blades too on a fluid bed setup. It's just a small motor so I need the TC4+ MOSFET.
I usually let the DC Fan run until I get the temps down to about 40 degrees Celsius/100 degrees fahrenheit before I shut down.
Been roasting for about 3 years (with manual controls). Never had the blades melt on me (yet) LOL... But I agree that's a problem.
I've been thinking about it and may stick to manual controls on the fan (the artisan control will be a "good to have").
Cheers!
