Will a Vaillant 150 Timeswitch fit and older Ecotec?
I've got an older Vaillant Ecotec combi with a 130 Timeswitch that's broken, can the newer 150 timeswitch be used on it rather than paying over the odds for a 130? I know you can put the pins in a couple of different positions but can't remember if it fits the older ones or not. Thanks in advance
