Hi,new to this forum. I'm swapping from sz2301 valves to Szm1801 valves to see if there any better as the spring return ones only last a couple if years before either the micro switch or the motor gives up. Is the wiring the same as it looks slightly different. The brown and blue wires for the motor look the same but it says the grey wire must go to a permanent live where as on the old ones I don't think it was.
Thanks,Bryan
