Good morning all,
My first post and hopeful of some advice. I wanted to know if there’s a way of testing timeclocks, more specifically a Vaillant Timeswitch 150. I’ve just changed one as I believe after speaking with Vaillant technical that these can cause an intermittent heating on when demand is off situation? I’m currently still in a new repair position with little help from other engineers. I checked the diverter by running the dhw and doesn’t appear to go up the flow pipe. I’m going to be registering with the CC.
