Economy 7 timer wiring

[MirfDiver]

I bought an Economy 7 timer for my immersion heater.

Currently there are 2 x switches on the wall. One labelled restricted supply (eco7) and the other labelled unrestricted supply.

Both have a red and black wire going in at the top plus a brown and blue wire going in the bottom.

Now, I thought this would be a reasonably straight forward wiring job but I'm a tad confused by what's required.

Can anyone help me ascertain which wires need to go where in the new timer?

How many immersions do you have fitted to the cylinder?

Currently there are 2 x switches on the wall. One labelled restricted supply (eco7) and the other labelled unrestricted supply.

That suggests you already have a timed supply (the restricted one) which will be switched either in the meter or by a separate timer wired to the meter.

What is the make and model of timer you have purchased?
What exactly are you trying to achieve by fitting the timer?
Please post a picture of your electricity meter and any other equipment fitted near to it.

Timer is a Horstmann (see pic).

The economy 7 set-up is in an annexe building that will be sublet on a casual basis. I want to stop tenants having the unrestricted immersion on all the time. With the timer they'll only be able to boost it for up to 1 hour at a time.

Pic of the meter also attached.

Thanks
