Economy 10 & Smart Meters

@PZ19 I "think" what they are trying to say (and whoever wrote that reply to you doesn't fully understand the situation clearly either!) is that the Second TOU Rate 1 and Second TOU Rate 2 will be added together and treated as Off-Peak (along of course with the normal TOU rate 2).
 Whilst the three "off-peak" TOU Rate Register readings should be shown separately on any bill, they should all be charged at the off-peak tariff rate. The only Peak rate is the first TOU Rate 1.

Just for clarity, now that we understand that this 1422-B's display is similar to the updated 1416-B's we mentioned earlier, when the off-peak is active ie. the ALCS is closed, LC2 will be on the display - (but not additionally LC1 as on a 1416-B and some others as that's the separate 2A switch not present in the 1422-B). You also have the red neon indicator on the water heater switch if turned on, to show when off-peak is active.

Otherwise, in standard rate the switches on the display will show as your previous picture -

Cheers Chris, thanks to your help and others in here I now completely understand what’s happening. Like I say I take daily readings as I’m a financial/numbers geek so know exactly what I am using and what I should be billed.

No more news on this, until they have their solution fully tested.  Have it in writing I won’t be overcharged for the water/heat “peak” readings.  I know exactly what the bills should be and will be sending them that this morning so they have that in writing. As obviously today the tariff rates change again (2nd time since had the not so smart meter)
