Moving to OVO Economy 10 (with or without storage heaters)

Firedog: My WAN and HAN lights are flashing green every 5 seconds. They are very faint and difficult to see.

Sometime, maybe Monday or Tuesday, two messages appeared on my IHD, both the same - ‘elec meter initialised’. Any idea what that means? I cannot find anything on-line in the IHD documentation.

Firedog: My IHD is now showing an MPAN and OVO as the supplier. I am guessing that means the meter is communicating with OVO. The Economy 10 off peak supply is due to come on at 14.30 and I will post then if everything is OK.

Yes @Keast 

As requested @Firedog 

Please find attatched the following pics.

Hot water heater, one always on?

In my THTC setup there were two supplies for hot water coming going through a switch. One was taken from the off peak supply, the other was a boost taken from the 24 hour heating supply (both these supplies were charged at the off peak rate). If Crag has a boost switch somewhere it may heat his water because when my new meter was installed the 24 hour heating supply was combined with the 24 hour domestic supply. The boost can therefore be used until the Economy 10 off peak is initiated.

I can’t see from the photo’s if Crag’s setup is the same as mine. 

I noticed the wireless icon on the IHD is flashing, so not sure but is this wireless capable as i have broadband. It’s just there’s no info at all on how to operate the IHD.

Quite possibly if you or the engineer linked it. From your photos, it looks like you have an IHD3 which is a Chameleon manufactured device.

Because of changes described in my previous post I expected my off peak supply to come live at 14.30. It didn’t and I am now very confused.  I will need to this photo of my meter box to explain what happened.

Working from right to left, I believe the following.

Junction box 1: off peak supply for  a) storage heaters b) water heating.

Junction box 2: 24 hr. supplies for c) lights, power points, cooker, etc. d) panel heaters and emersion booster.

Junction box 3: Neutrals. I have two fuse boxes; one for c) and one for a) b) and d). 

The device in the bottom corner is a monitor which talks to an energy diverter which controls my solar power.

Following meter replacement devices receiving power from Junction box 2 operated as expected. The storage heaters would only charge overnight at times equivalent to Economy 7. 

After 14.30 today I detected a strong current on the live feed to Junction box 1 but no indication that current is flowing to my storage heaters. 

My question is: how can a supply which successfully got through Junction box 1 last night and charged one of my storage heaters not do the same today?

FYI this is a photo of the meter cabinet before the change. I am having a go at interpreting the spaghettis and can provide that if necessary. The RTS meter is on the right.

Thanks for the pictures (at last!)

It looks like your interpretation of the cabling to/from the three white junction boxes is correct. The brown line tail from the fifth port on the meter (the one nearest you) leads to the right-most junction box, where it splits in two, one labelled W (for Water, I suppose) and the other ST (for STorage heaters, perhaps). The middle junction box also splits the feed in two, one for each of your 24-hour CUs. 

It would have helped if you’d touched button A on the meter before taking the picture to switch the lights on - it’s not easy to read the display. To me, it looks like <1kWh import has been recorded on TOU Rate 2 (which should be the offpeak register). The contactor symbol in the bottom right-hand corner appears to be open, meaning that the switched circuit wasn’t live at the time the picture was taken. 

I think there’s something you’ve misunderstood: while communications seem to have been established between the meter and OVO, it may take some time for all the normal configuration stuff to be transmitted - the tariff, for example. I suspect the smart team will wait until it’s settled down completely before attempting the ECAUL request to configure the ALCS, which should then start switching the auxiliary load at the times appropriate to Economy 10. 

I’ve no idea, I’m afraid, how your solar power generation fits in to this scenario. @BPLightlog (our resident renewable guru!) may have some ideas. He may know how to explain the left and down quadrant arrows in the bottom left-hand corner ...

It all takes time, I’m afraid, so you may have to be patient a little longer. 

Thank you Firedog. In my defense I need to take photo’s with my IPad and email them to myself and then use my laptop to copy them and paste them to this blog. I know!. It is all about being more comfortable using a keyboard.

I don’t remember seeing any thing about being ‘patient’ in OVO documentation. If only they had indicated there would be a delay.

There is a saying, ‘If he had a brain he would be dangerous’. I have and I think I might be.
