Few questons are still unclear for me.

1) how to link AE and PA?

AE has two 4-pin connectors aquabus



and PA has one (or two?) 3-pin connectors



Do I need special cable or I may make it myself from common fan cable?

2) How to connect two PAs and AE? PA no.2 connect to PA no.1, and PA no.1 connect to AE?

3) If I have flow and temp sensors connected to PA no.1, will it be seen as common sensors in aquaero, so I could program PA no. 2 depending of sensors connected to PA no.1?
