Does anyone have a USA source for the three-pin relay and two-pin PWM connectors for the Aquaero controllers? I'd order from the Aqua Computer shop, but shipping is more than $45 for less than $10 in parts. I've tried locating the components myself-- they look like something provided by Molex, Phoenix Contact, or On Shore Technology, but they have such a wide variety of components that it's like finding a needle in a haystack. Thank you, Malachy

While looking at other posts, I stumbled upon a link to the D5 product announcement, which states that the Aqua Computer D5 pump motor controller uses the D5's native speed control, whatever that mechanism is -- I've see references elsewhere to five speed settings for D5 pumps. Overview of all new products from the last days

What method is used, internal to the pump, to control the speed of the Aqua Computer D5 pump motor? Does it use a transistor to adjust the voltage to the motor, for example, or have an internal PWM generator? Thank you.
