Economy 7 clock wrong

[JohnW2]

Obviously, there has been some mix up in the swap, from the original meter system, where there was just a single supply tail, and the OP had his off-peak CU fed from his own clock, and the new meter.

I doubt it ....

The OP needs to find himself an electrician, to simply swap his off-peak CU over to this off-peak meter tail.

I think you'll find that it already is connected to the "off-peak meter tail". The folk on MSE seem to be saying that this has recently been a fairly common problem, with the settings of the 'clock' controlling the off-peak tail being out-of-synch with the E7 'cheap period" and that this can easily be reprogrammed remotely by the supplier (Octopus)

His supplier, Octopus, will not be able to help with this.

Seeabove. If the problem is as has been suggested, then Octopus are probably the only people who can rectify it.

Doesn't the off-peak tail, switch on and off the supply, as controlled by the supplier?

In which case, I cannot see how it can be correctly wired.

Indeed it does - but on and off at times specifically programmed by the supplier (which, as probably is the case with the OP, are not the correct times for 'E7 tariff change'.

Why not? If what is being suggested is the correct explanation, then the 'off-peak tail' is, as intended, turning the load on and off, but not at the correct times (because of incorrect setting./programming of its clock)

That would be a bit pointless, don't you think?
