Immersion Heater Timer Connection

[nikosof]

Hi all
I want to replace my ageing timer for the hot water cylinder immersion heater, and I am unsure of the connections! I have a Drayton LP111 (the plate connections are N,L,1,2,3,4 and E). The current timer (Superswitch -no extra model details on the face) has 2 N,L connections (one 'ouy' one 'in'), one for the heater, one for the timer. The switch is connected with the 2 Ls and the 2 Ns are connected with a wire to each other.
So, my question is how to transfer these to the Drayton!
Btw, I've tried the plumbing forum with no response. Many thanks!

you dont

you already said you are changing your old timer so there for you do not transfer anything to it.

what do the instructions for your new immersion heater timer say?

Its probably something like supply in supply out,

supply in being from you fused connection unit, supply out goes to the immersion heater itself.

you must also join the earth wires together

A LP111 is a CENTRAL HEATING control time clock.

Me thinks it will not last long if you wire it up to an immersion heater.

Do not do it.

It sounds maybe you are trying to go beyond your limitations. Get someone in to do it who can certify.

thanks baldelectrician.
the funny thing is that the guys who installed the cylinder (i had it replaced) bought this and brought it along for this purpose. They didn't connect because they didn't know how to. So what kind of timer would you recommend for that?
tks

yep, my hot water cylinder only uses the immersion heater element to heat water (not connected to boiler).

Try one of these

I find them more reliable, less prone to people fiddling with them and easy to replace.

Replaced one last week, it was 10 years old.

(that's the shortest time i have seen one last- date code on back when you remove it)

go for the HO E7Q version, easier all round - does what it says on the tin
