Myson MPE222

[bruce2]

I have installed a new timer and I have replaced the 3 manual valves with Myson MPE 222s I have tested the valves and they are fine I now need to link the boiler to the system There are two extra wires - orange and grey. I have connected the positive wire from the boiler to either of these two remaining wires but the boiler does not come on when the valve is activated. Is there a time delay until the valve is fully open or how do I connect the boiler.

All help appreciated

The orange turns the boiler and pump on.

The grey tells it too.

In case

Blue is neutral.

Brown is the call from the cylinder or room stat.

Grey is permanent live.

Orange is switch live.

Hi Again
The Sunvic 307 XLS programmer seems to have crashed twice since installation and I have great difficulty resetting. However I get it working thanks to perseverance rather than having a troubleshooter guide. The following comes up when I commence re programming -9:7E. Does anyone know what such means or how to reconfigure the whole thing again.
