Jebai CP-120 with AQlink A1 connected to Apex

Hi

Petty new to apex and need some guidance
Ive connected the AQlink A1 to the apex, and what I have read up is that Jebao cross flow uses 1 port with 2 channels. The manual says ch1 for direction and channel 2 for speed, which im sure is the wrong way around. When I adjust channel 1's speed, the flow increases.

My question is, does channel 2 have to stay on auto or on?
When I switch ch 2 off the pump goes into reverse

If you want the pump to always operate in the forward direction, program that Apex variable port to be ON all the time:

Fallback ON
Set ON

Then leave the slider in AUTO.

Thanks Russ
