3-Way Lighting Problems

[thejolyroger]

I am trying to replace my switches on my hall and landing with these.
2 Gang 2 Way White IQ Master Remote - Touch Dimmer (I have 1 of these)
1 Gang 2 Way Slave Dimmer (I have 3 of these)
Downstairs I have a 1 gang switch with Com, L1 and L2 controlling the downstairs light
Downstairs I also have a 2 gang switch with Com, L1 and L2 on one side Com, L1 and L2 on the other side controlling the downstairs and upstairs lights
(On this switch there is a small cable that runs from the com on one side to the com on the other side and only one com has a cable going out)
Upstairs I have a 1 gang switch with Com, L1 and L2 controlling the upstairs light
Upstairs I also have a 1 gang switch with 2 x L1 and 2 x L2 controlling the upstairs light
The problem I have is each new switch only has Live, Slave and Load. I can do this for most of the switches by putting Com to Live and L1 to Load and L2 to Slave.
What do I do with the upstairs switch that only has 2 x L1 and 2 x L2. I tried putting both the L1's to Load and both the L2's to Slave but it did not work.
Any help would be greatly appreciated.

I'm sorry but the best advice that can be given here is to consult a local electrician, it's a fairly simple job if you know what you're doing but it appears from what you've said that you don't. Please note that is not intended to be a put down or a dig at you.

the switch wih 2 L1 and 2 L2 is an intermediate, you should have another two wires joined in a connector in this switch, depending on the wiring method, you need to get an intermediate switch for this one

IQ lighting is not your usually lighting control and you will need 1 master and 2 slaves wired across the existing 3 core, now the problem is you will need to identify incoming live and load live, and this is were you need to get a electricain in, as with any processor controlled device...wire it wrong and youll be replacing the units every time

I did ask two separate electricians to look at this and they could not work out how to wire it in, one said I would have to rewire the whole lighting setup, but surely that is not right.This is what the instructions say:

Using Master and Slave Units in 2-Way and Intermediate Circuits 2-way lighting circuits have two switches (intermediate circuits have 3 or more switches) turning the same lights on and off from 2 (or more) locations (eg. at the top and bottom of the stairs). In suitable circuits one of the switches will have a live wire connected. Replace this switch with a Master Dimmer and the other switch(es) with Slave Units to allow dimming from more than one location. Note: If your 2-way or intermediate circuit does not have three direct connections between the switches (as in the diagram) the circuit must be rewired using conventional "2-way" wire (red, blue, yellow & earth). Master Dimmer: Connect the live wire to the terminal marked "Liveo" and the "load" wire to the terminal marked " ". Slave Units: Must be wired to the Master unit as follows: "Liveo" to "Liveo", "S" to "S" and " " to " ".

I am not going too deep into this but the first impression I get from your wiring description is.
The live feed picked up downstairs where the hall switch is located,a pair of strappers to an intermediate switch,then a pair of strappers to the 2 way switch upstairs and a switch return at that point

You meed to get a live feed to the master switch
You don't appear to have 3 core looped between the switches,that diagram may not be appropriate to your set up

The IQ wiring diagram is simple enough, and your existing wiring is simple enough using 2-way and a intermeadate switch.
I can not see how an electrican can not id the supply and the load feed, then wire this for you. The live feed and the load live can be connected on any of the 3 light switch positions, as masters and slaves are all linked. But as Des and i have said the feed and load need identifying and this is a simple test proceedure for a professional electrician
