Wireless Programmer Advice

[hightower]

My mates just been on, his combi boiler isn't working with the timer so he's asked me to install a separate unit.

First of all is this even possible, and second can anyone recommend a budget programmer that would do it. Think it would need to be wireless programmer unit with a receiver at the boiler. I was having a look at a Salus model for £35 but think they are single channel? I'd need 2 channels I think

Sorry, it's a combi boiler doh, so I'm right in thinking I only need a single channel (for the heating) as the hot water will come on automatically when water it called for by the tap?

This is the one I was thinking of getting to fit?

If you're looking for something slightly more expensive but two channel then I'd recommend the Heatmiser SlimlineRF Kit, simple to use is a tidy little unit.

You only need a single channel bucause combis are instant water heaters.

Will the boiler be capable of having it if the boiler is expecting it to use its own timer? Or is it just a case of setting boiler to permanently on and then dropping this in the current thermostat switching?

Should be more than capable, you turn off timer on boiler set to 0.
Then a 4 or 5 (depends how you want to do it)core cable from reciver to boiler.

Sender unit switched live to switched live in boiler.

Make sure that your on the right terminal in the boiler.

For example, Vaillant have a 240V , 24V and ebus circuits and a lot of others have similar options.

Most combi boilers offer a supply for the circuit you choose too.
So your programmer is just a switch for that particular circuit.

Any RF programmer should work any boiler though, it doesn't need to be same make.

You are supposed to be gas safe registered to open boiler case though.

Thanks. Think I need to look into 230v and 24v contacts a bit and see what all that is about....

Hi mate, I have no idea. I'll drop him a message to find out.

 

[hightower]

@Leesparkykent It's a Worcester green star 25si

So looking at manual I believe I need to take the Ls to the common of the receiver, and the Lr comes from the NO of the receiver to the Lr on the boiler. Would this be right?
