Hi,

I'm curious, does a fan controller like the Aquaero work simply like a variable potentiometer? Is that the basic principle behind it... providing a voltage across the pins proportional to the "electronic" pot setting?

Is it therefore safe to assume that most fan controllers and the Aquaero could replace the POT on the D5/MCP655 pump that is used to control the speed?

Here's a thread on [H]... http://www.hardforum.com/showthread.php?t=1068890

I may try this mod if folks who understand the Aquaero can confirm that its fan controller can indeed replace the POT on this pump.

Thanks!

^ Probably because the MCP655 he's looking at can hit 1200 l/h and has 1/2" barb connectors - it's intended for larger bore loops.

That's correct.  And note, I never proposed controlling the MCP655/D5 pump directly... I know it's power requirements far exceed the output of the Aquaero.

However, the MCP655/D5 pump has a POT which simply acts as a voltage divider to the pump's microcontroller to set the operating speed of the pump.  My question is, a fan controller, like the aquaero is simply a voltage divider as well, right?  It simply provides 0-12V across the appropriate pins.  So regardless of what the fan controller was designed for, the bottom line is it is an electronically controlled POT and can likely therefore be used to replace the manual POT in the MCP655 and thereby control the pump.  The only question to be determined is the voltage range the MCP's POT works over... is it a 12V divider or a 5V divider?

Does this make sense?

Why is there so much resistance here to trying new things? The makers of aquacomputer stuff should be excited to see their goods being used in ways they never considered.

We will lauch a controller in a few weeks. Maybe this will be your solution.

What does this mean?  Can your provide more information?  What kind of pumps will this control?

I'm actually leaning towards the 18W DDC Ultra pump now.  The MCP655/D5 sounds too loud for me.

Thanks!

EDIT:  Actually, I'm going to start a new thread on this since we have diverted subjects... (See thread titled "Using Aquaero to control other pumps")
