    Hi guys, I have a 100 watt vitodens wired with a two channel time clock. I used the extra terminal module for the hot water x4, and it switches in fine on central heating and hot water, however when I have the central heating on and hit hot water it overrides the central heating. The wiring is to the schematic. Has anybody an idea what could Fox the override problem as I want them to work simultaneously.

    Many thanks.

    It sounds like you want to disable the domestic hot water priority? Why do you want to do this? It will decrease your domestic hot water recovery time.
