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.
