Hi Ladies and Laddies,
Could anyone help identify the terminals for this old combi? I arrived at the property which has been undergoing a renovation for the rental market, the client reported the boiler not working, when I began investigating the flex cables going into a mechanical time clock had been disturbed. I found the connection info for the time clock online but I cannot do so for the Valliant VCW.../1W combi. In the photo you will see the terminals 1,2 are supply in, but I am struggling to determine what terminals 4,5,6 do. The set up will be using a new time clock, as the original seems to have suffered over time and a two wire mechanical room stat.
Thanks in advance for any insights.
