immersion wiring

Bought a zwave smart home immersion control
http://products.z-wavealliance.org/products/1012
which seemed like a smart idea but
the zwave is about the size of a normal plug-has three wires in -three wires out. i wired it op for connection to the immersion.
The immersion has four wires blue/black/brown/earth.
assuming it can be done, which three meet the zwave and is the extra joined up outside of the zwave?
thanks in advance

Have you removed the bath/sink switch?
This control should go before the bath /sink switch. It does not replace it

Thanks for your reply. I put it between the bath/sink switch and the immersion with the intention of leaving the bath/sink switch permanently on while the zwave controlled the actual flow of power to the immersion. I assume that is not the idea.
if so i need an electrician.

The timer comes first. This controls turning the power on and off to bath/sink switch. You leave this switch on then. In my own set-up I leave the switch on bath all the time so I have a full tank of water.
Only you can decide if you are capable of installing it. The law says that you must be competent. If you are unsure I'd suggest getting an electrician

Sleeper12-if I could ask you one last question. See the link showing the current setup

the timer is then connected to the bath/sink switch.
Are suggesting installing the zwave between the switch on the right in the photo and the timer?

The switch on the right is a spur someone took off the immersion. Possibly for a power shower or pump.
It's looking more complicated. Definitely get a spares if you are unsure

Old thread but here we go.

Any idea what the brown is coming from the stat on this old immersion?

Will need to be changed as sink is tripping RCD.

If you are replacing the immersion then the new one will have its own cable pre wired. You the connect the other end to the sink/bath switch.

You might end up having to replace the cylinder too if things don't go smoothly
