New heat pump Daikin EKHBRD016ACV1 , AE error, external pump

Hello there. I recently had a Daikin heat pump system installed (air to water).
However, the system displayed AE error on its remote control five minutes into operation. Also, not all radiators heated up.

I was told the system pump was not enough, so an external pump was added.
This allowed all radiators to warm up. However, the AE error is still present. It never goes out. I also worry that the external pump is running continously; increasing the electricty bill.

I am at a loss why the AE light would not go out, I aired and added water to the system up to 2 bar. Any suggestions would be welcome.

Also, does anyone know if the external pump can be connected to this unit, so it can be turned off and on by the unit? Currently it's just connected to the mains.

many thanks, -tk
