See image sent. The arm is shown in the down position = Central Heating. Whin the controller moves the arm a 1/4 turn up it is in the Domestic Hot Water position.Hi good evening,
TheGrundfos pump arrow on the front is pointing anticlockwise so is pumping up.
I removed the Drayton 3 way mid position motor controller to check if marked A or B and it was not marked.
