Hi all! I’ve just recently had my prepayment meter replaced with an Economy 7 credit meter on nPower. I would imagine that it would provide power to the storage heater / main immersion heater consumer unit under the control of the radio teleswitch, giving 7 hours of heating sometime between 2200 and 0700 depending on how nPower have it set up.
Last night it came on around 2330 and, when I came down this morning at 0650 it was off. However it had came back on again at 0700 or so which has me confused!
My other half spoke to the engineer as I was at work and he said that the storage heaters we have (Dimplex XL series) can be left on at the wall at all times and the radio switch will provide power into the CU and therefore act as the switch for the storage heaters etc.
Wiring wise, I have two electricity meters, a radio teleswitch and two consumer units wired up as follows:
Domestic Meter: 1 – Live – Brown cable – from main fuse
2 – Neutral – Blue cable – from main fuse
3 – Neutral – Gray cable – to domestic CU
4 – Live – Gray cable – to domestic CU
Storage Meter 1 – Live – Brown cable – from main fuse
2 – Neutral – Blue cable – from main fuse
3 – Neutral – Blue cable – to a junction box, splits, has blue to radio switch and black to storage CU
4 – Live – Brown cable – to radio switch
On the bottom of the radio switch there are 8 holes, from left to right, with a brown cable linking 1 to 3, the 4th cable (Brown) from the Storage meter into hole 2, the 3rd cable (Blue) from Storage meter into hole 4 and a gray cable from hole 8 going to the Storage CU.
The radio teleswitch is a Series 2D type NU045-9003 and has a sticker saying Group Code 98 North on the front. The meters are Landis-Gyr 5258K and, on the storage meter, the red led to the left of the pair is lit constantly when there is no demand on the storage circuit.
I hope this makes sense and hopefully someone can explain why my electricity is doing random things. The previous prepayment meter was an Economy 10 I understand and the radio switch was not changed yesterday.
Thanks in advance and sorry for war and peace! David
