Why are my storage heaters not coming on with my Secure Liberty 100, no 'boost' mode, no off peak night rate?

Did you get the problem sorted ? I have a similar issue.  Our supplier has "accidentally" switched us from E10 to E7 without telling us - I spotted it coincidentally only a few days later. It is taking forever to get it sorted,  and they are saying they might not be able to fix it. We have the same set up as this,  with a 4 leg meter and one of those Proteus contactor boxes. Our heating is still coming on on the E10 times while the tariff is on E7 timings. What I am trying to find out is where the Proteus box gets its timings from. Is it something I can alter myself via the meter ? 

Hi @Sandydog ,

I’m afraid the other users in this thread have not been seen for several months, so they might no longer respond to anyone.

I’ll do some digging to see if I can figure this one out, which might take a few days. If I find anything, I’ll let you know.

Thanks, that is very kind.

Great to see our superuser @Blastoise186 has got his meter investigation hat on already. 🕵

Sounds like your external time-switch (the Proteus box) might need to be reset to align to the hours offered on dual rate plan. Wonder if @superstarmie might be able to give us an update on how they managed to get this sorted in their case?

Ok, I think I understand this now. For legal reasons, I have to inform you that I’m not a qualified electrician myself and can’t make claim to fully understand exactly how these Proteus external heating contactors work. I could “phone a friend” though, but I think I’ve got the basic idea figured out.

As far as I can tell, these external contactors are pretty simple switching devices with no real “smart” capability of their own, nor any built-in timers. It appears they require something else to tell them what to do, such as by powering them with a control signal which causes these Proteus devices to react accordingly.

This suggests it’s all ultimately controlled by the meter, but perhaps the meter config hasn’t been updated correctly?

And right about now, I suspect a real expert will probably completely smash this theory to pieces! XD

Thank you for helping us. It's obviously something that only the electricity supplier can sort out,  and they aren't helping. What puzzles us greatly is that the proteus is switching at E10 times while the meter tariff is switching on E7 times.  Therefore whatever is telling the proteus when to switch, it isn't the meter tariff times ! It must have a stored timer setting in the meter independent of the tariff switching.

So we are stuck with an E7 tariff which can only be used for 4.5 hours per day.

Thanks for taking the time to help us understand it. 

I think it’s a different part of the config for each task. Chances are somebody forgot that crucial factor again.

To be honest, most of the installs that use these Proteus devices were cases where the supplier was either unable to source a compatible meter, or were being too pushy about it and couldn’t be bothered to wait for the right types to launch before aggressively pushing people to upgrade. I’ve not seen any indications that OVO has ever done this, but I know of at least one supplier that has been known to do it. For their sake, I will not name that supplier at this time.

Just curious, but who is your energy supplier? The house rules here allow you to mention competing suppliers freely, so don’t worry about upsetting the moderators. It actually sometimes helps us out to know these things, as there might be options I can recommend based on them. :)

The supply was Eon, as I'm sure you've worked out ! They retired the Economy 7 with Heatwise tariff in 2019. We previously had a 5 rate meter with E10 for heating and E7 for everything else.  They fitted a smart meter as we weren't allowed to keep the old meter. We didn't know about the fudge with the timer until noticing this problem.  We have had to try and work out how it all works from googling it. 

It has worked perfectly for us for the last 2.5 years to be fair though, before this nightmare started.  I wonder how many other customers are affected who don't even know yet. Its hard to believe its just us. 

Hehehe, I had a feeling it was E.On right from the start. I can’t think of any other supplier that’d be so impatient that they’d force through this sort of thing so quickly. There’s probably a ton of other affected sites as well and I’ve seen previous evidence of that on this forum. It’s not just you.
