Not sure wether this belongs here or in the central heating section.
I had a request to inspect a client who had no hot water, and it turned out she had a three way switch controlling her immersion. It positioned as mains, off and economy 7 supply. Now the switch is no longer operating on the mains side, and due to it's age, it needs replacment.
In the past I am used to connecting programmers and timeswithces but havn't come across one that will allow for a dual supply (off peak and peak), and then connect down the same cable to the immersion.. is there one?
