Dear all - I am trying to replace my st699 with a tado smart thermostat - my question relates to the wiring on the old st-699: I have bridge links between L-5-8, but I have another wire attached into terminal 8 which looking at all the sundial wiring diagrams on st-699, it is not shown.
Can someone explain the hot water wiring to me? My tado instructions thinks the hot water should be wired in on terminals 6 and 7 - but it looks like mine is on terminals 6 and 8? I am concerned that pretending this non-bringing wire on terminal 8 (which is connected to live) is the equivalent of wire 7 on the tado may either damage the tado or result in incorrect operation.
Thanks in advance,
Adam.
