QE7 eco 7 - manual over ride? Help needed

[c088161]

Hi there,

This may all be very basic so apologies in advance. I would be grateful for some help!

I have a QE7 timer attached to the boiler however there are a couple of switches above the timer and i'm unsure of their function.

I think they are manual over ride switches so I don't have to tamper with the boost and timer however I need some expert opinion!

Pictures below:

with regards to image 4 all i can really fathom is that they are linked to the off peak and on peak immersion heaters

I look forward to your advices.

Many Thanks

One of those switches is probably the isolator for the timer and elements.
Impossible to know what the other one is for.

The correct method of operation for that timer is:
1. set the clock by rotating the dial so that the current time lines up with either the 'summer time' or 'winter time' arrow
2. set the off peak times by moving the small levers outwards for the off peak period (2am to 6am should do)
3. make sure all of the other levers are moved towards the centre (in the picture they all are except one).

The water will now heat up overnight. If extra hot water is required, turn the small timer button to however long you want the element to be on, and press the button.

The switches above won't be for 'override' or anything like that, as that is the whole point of having that timer fitted.
If someone has wired the switches above to activate the elements permanently, they were a fool and didn't have a clue what they were doing.

Just be aware that E7 times can vary, where I live E7 switches back to normal rate 00:30 - 02:30

Hello there,

Many thanks for the above replies - much appreciated...I'm sure I'll figure out what the switches do!

I had an email reply from british gas regarding the 'off peak' times. For the Norweb area the standard Economy 7 times are between:

10.30pm - 12.30am and 2.30am - 7.30am

They're still making it all quite confusing though so i'd better ask more questions!

Thanks again

Hello again,

sorry to be a pain but I'm sure someone can advise me.

I've received the following reply from BG:

'If you have an Economy7 meter with a timeswitch (a 24 hour clock) attached, you will be able to see pointers confirming the times that your meter switches over. But please remember that when the clocks go forward for British Summer Time your timeswitch will be an hour behind.

However, if you have a teleswitch on your meter, which means that your meter is controlled by radio waves and there is no mechanical clock, there are no pointers for you to check.'

When they mention timeswitch I'm guessing they're referring to image 4 that I attached earlier and not anything to do with the meter which is in a different location altogether - and the radio waves do not apply at all.

The other thing is, the levers on the rotating clock are only activated when they cross the 'winter time' arrow so I've made the winter time arrow point to the current time - meaning the summer time arrow is completely irrelevant!

Sorry to waffle on - can someone clarify that what I've done is correct?

Cheers

When BG talk about a timeswitch, they mean a device next to your meter which changes the meter to the low rate. If there is no sealed timer there, then there may be a black box with "teleswitch" on it, or a meter with "teleswitch meter" or similar written on it - most modern eco7 installs feature an all-in-one meter that changes itself to off peak when required.

This is the normal setup for a white meter installation. It may well not work (and could explain the two FCUs) if this is a seperate peak / off peak supply.

@OP Can you post a photo of you electric meter(s) and fuse box(es) and associated equipment?

RF Lighting - I'll get some pictures up as soon as I can..

Thanks for the help.

Cheers

Another thing I should mention.. the time on the meter is actually incorrect by around 15 minutes.......
