If so, are you able to advise which of the three IR control wires go into which connectors on the control box. I have fitted my screen today and completed the wiring but the unit is absolutely dead. There is 240V going into the control box and the fuse in the box is good. The IR sensor has 3 wires from it, blue, white and yellow but the instructions and the markings on the PCB connectors refer to the wires as C, Si and +. No mention of colours. Can anyone help out here. BTW, I have not fitted and do not want to fit the manual switch. I am assuming (nothing in the install sheets) that I can use just the IR control with no switch or am I wrong here. Thanks.
