RTS Switch Off Meter Query

That's encouraging, but there's one more unit I have, it's on the wall outside the boiler, this is the switch that's always on for the hot water.  Would this be anything to do with a possible RTS connection....?

RTS devices usually have "Radio Teleswitch" written on them somewhere.

I thought so too, and as yet have not been able to locate anything like this.

No, that's the immersion heater timer. I have the same model.

Brilliant!! Thank you so much Stripe and BarelySentientAI - you've both put my mind at ease

Absolutely correct.  As far as the supply is concerned, that's just the same as a lightswitch.

That's a junction box (often called a Henley block).  Makes sense.

If there's nothing else, then it must be the 5-terminal version of the meter (which has a timer built in).  Didn't look like that from your earlier photographs (or the first wiring diagram I found), but there is one.  You can check that, if each of the cables coming out of the bottom of the meter come out of a different hole then it's the 5-terminal.

That means that your system is not RTS at all.

Just confirmed it's a 5-terminal, 3 reds and 2 black cables coming out of the meter - yay!

Here's a pic of the meter as requested.

That actually looks like a 5 port meter - the feed to the grey CU box below looks like its forward of the other meter tails (a not uncommon physical tail arrangement - but others are simply 5 in line)  - being given the restricted time supply.

So if so that CU will be for hw immersion and night storage type heating or even some aga etc)

The govt certification certificate I found shows terminal arrangements for both 4 and 5 port versions.
It makes no reference to RTS timing or preset etc - its not a full spec just a certification certificate.

And the EDF prepay key manual for it shows how to read both a single rate and dual rate e7 version - so one or 2 active registers.

Would need an actual ltron / actaris etc  manual or data sheet I suspect  to be sure.

Assuming the red meter tail possibly from the 4th port running horizontally behind the neutrals labelled 2 etc - is actually connected to the meter.

It's a bad photo of meter bottom and colour contrast to tell for sure but you can just make out itbturing upwards - albeit a tight bend radius.

It's not impossible that a single block meter has RTS fixed or variable timing functionality - some 3 rate sse rts meters were single unit iirc.

but it's far more likely to be fixed preset timing given its a fairly modern device and plans for rts been on way out for several years.

Anyone got a meter spec link ?

That's an immersion hw heater timer with optional peak rate boost - do you have 2 tank elements or one ?

Nothing to do with RTS at all.

Hi Scot, my query has been resolved, but just for info, I have 2 tank elements because I have an open fire that heats one of them

Mine is definitely a RTS and I am being hounded to get it upgraded. Unfortunately my existing supplier can only supply a new meter that has E7 times of 12.15 to 7.15 whereas my existing is 1pm to 8pm much better times for me. 

Will they extend RTS beyond June 2025. 

Thank you.
