I went to reinstall this morning, and am unsure of the configuration now, attached are three photos I took

- Port AB seems to come from the loft
- Port B goes to the boiler
- Port A goes somewhere else in a void
The motor head when switched off in rest, points to port A
I can move the actuator to Port B, it sits about half way pointing upwards then stops. However, when I move the motor head socket to the new position, the springs want return it to the port B position
According to the Honeywell manual, port A is CH, port B is HW, but on this configuration I don't know nor understand
I'm totally lost and confused
