Default HFS2 vs HFS3 help identifying what i have


So I have a controller box that says HFS3-PWM and then I have what corresponds to the HFS2 kit (dash button).

Is it correct that the difference between the HFS2 and HFS3 is the dash button vs dash gauge and flow sensor?

I was unsure if the HFS2 controller box should have a label that says HFS2-PWM or will it say HFS3-PWM?

Problem is I bought it 5-6years ago as a HFS2 kit, so now I'm unsure what I have.

The HFS2 uses the same controller as the HFS3. The differences are the contents. It doesn't come with a flow sensor tube, flow sensor cable, no gauge and no gauge cable. It does come with a dash button.

You must be aware of those major difference or clues to help you identify what you have. For some unknown reason you have chosen the controller instead.

If you contact aquamist with w serial number on the controller, they will be able to confirm what you have.

You have a HFS2 system.
