    Thanks in advance. I have a valiant EcoTEC whilst the flow temp is set to 70 the heating flow only reaches a max of 45 when heating is demanded.

    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
