Hi All, hoping someone can advise how /which buttons I need to press on the above model, in order to see the current time displayed. Thanks in advance

On the older 100 series like mine - I have to use iirc 6 for multirate register cycling imp r01 and then take rreading and again for imp r02 and take the reading.

That might according to other posts have changed on later models - to 9 regardless - for both single rate and multirate. on mine 9 only gives single rate totals again as that list.

Its not the exact model - but it might be the same button.

Thanks for that. Think I may be grasping at straws anyway. Basically, my electricity app usage graph is showing incorrect timings and I can’t work out why.  I was up Saturday at 1.15a.m and heard and saw the active light come on for the hot water cylinder immersion kicking in. This is what the app shows, and that spike is definitely the immersion start up.  It’s as if the app is still in GMT not BST. Surely the app is only reflecting what info is being drawn from the meter though? Thats why I was thinking of checking the time on the Liberty 112. Any thoughts, anyone ?

Meters like the liberty are probably "permanently" locked to gmt as far as load control switching goes (the time restricted circuits for hw and heaters in older split wiring homes).

Mines is, so my 12 midnight -5am  gmt night slot starts at 1 am in summer.

The meters themselves iirc always record by utc / gmt.

The independent apps like bright, loop etc there are several can process those times differently in some cases by user selection.

No idea which (supplier ?) app that is - but others might recognise it and know what that one does.

So my Economy 7 cheap rate switch over starts at 23.24 and ends at 06.24. Both times produce a very audible “clonk” noise, from the airing cupboard terminal. Those timings are controlled by the supplier and are adjusted to match BST on the appropriate dates. As my Economy 7 water control is antiquated ( rented property) pic attached, I have to manually adjust to keep up with BST. What had thrown everything out is the supplier fitting the new Liberty 112 on 26/3 but not advising that my cheap rate switch over times had also been changed at the fitting. Used to be 12.10 to 7.10. The internal switch on this control unit is still set to come on at 2am until 7am. Everything is a mess and basically I’m stuck with not being able to set the dial to the true time. No worries. I will be sure to check all again when BST ends

Yes if like other similar economy 7 switches  the meter isn't in direct control - tge switches do not use a restricted fedd from meter, so the timings have to match your meter off peak.

My hw immersion is on the restricted supply from my meter.   I have no timer to adjust.

I'm on e10, so heats 3x per day, little overkill for a light user (my shower isn't hw tank fed).
10hrs supply, reduced to around 40 min summer 1hr winter power use  (2-3kWh typically) (unless have bath or wash car etc) by thermostat on immersion heater itself.

Is the clock on the water heater timeswitch set to the right time? I suspect it has to be set to GMT, so your picture shows the switch set to about 14:10 BST. If 24 hours later you've found that that's not right, just adjust it to show the correct time BST.

You should be able to tell from the meter what time the offpeak register (which should be the second tier) starts and stops recording. Ideally, the water heater will fire up a few minutes after the offpeak period starts, and will probably remain live for seven hours. The tank's thermostat should switch the power off before the offpeak period ends; it should only take 2-4 hours to heat up. If the power comes on before the offpeak period starts, you'll have to get creative with the clock on the timer. However, you say it's currently set to switch on at 02:00 - isn't that just fine? It will be heating up from 02:00 to perhaps 06:00, well within the offpeak limits.

Did you get an IHD with your new meter? Is that no help with establishing these timings?

It's not unusual for E7 times to change when you have a meter replacement. For E7 loads that are switched by the meter, this is invisitto the user.

It's only where you have a separate time switch - like you do - that it becomes an issue.
