    Hello All

    I have old Sunvic kit which I decided needed upgrading. The programmer I have is 22 years old and the room stat very 1980's (nice shade of creamy brown - yum). Anyway I now have a Sunvic 207 XLS a Sunvic wiring centre SWC2202 and a new room stat TLX 2259.

    Stupidly, although a competent DIYer (!) I left it too late to phone the Sunvic help line when I discovered that it wasn't a case of 'blue wire was in terminal 1 (old unit) blue wire now goes in terminal 1 (new unit). The wiring guide for the SWC2202 uses terminal labels that don't correspond to the labels on the new room stat or the old Sunvic Clockbox II, for example. Sadly I couldn't work it out using the colour of the cabling either (beyond earth neutral and live....).

    Bit of a long shot but I am looking for someone who might walk me through the room stat, motorised valve and cylinder stat connections based on this wiring guide (it's on page two 'unishare system') and the clockbox shown below:

    I am stuck without heating or hot water! :rolleyes:

    cheers muchly, I realise that this is a big ask.
