calleffi flow sensors

Anybody have any experience with the new Calleffi BX controller and grundfoss direct sensors?
The sensors came without plugs to connect to the control, and I can't find anything in the literature that specifies what side (supply or return) the flow sensor should be on. not that it maters for the flow reading, but the sensor also reads temperature and I would assume it needs to know what side it's reading from.
I'd love to get this system charged up today but I'd hate to have the sensors reversed and have to drain it down to switch them.

Found the answer
I found it in the heat meter literature, the flow sensor S1 goes on the hot side (supply)
But if anybody has any other experience with these sensors I'd be interested to here about it. Like why don't they come with plugs?0
