Replace flash immermat timer with something decent! Help.

[undertrained]

I’m not sure what to suggest then. How new is the build? Anyway of researching the building regs and asking the builder to put it right?

It's two years new, and I don't think there is anything "wrong" to put right, just not the best system. Anyway, can anyone help on the suggested wiring please.

Not without knowing which immermat you have, if you have a multimeter the immermat will have a live and neutral which will always be present as it powers the motor , another two switching wires that are connected to the boiler and tell it when to come on and off, cant tell you which is which by your pic, post a pic of the front of the immermat and see if it has any model name or number anywhere

Hi there, thanks, I'll post and pic and I do have a multimeter. Cheers.

That is actually an Immersion heater timer, are you sure it is controlling the Logic boiler? it could be done but certainly not the normal way to do things.

I'm 100% sure that when the timer "clicks on" the boilers "comes on".

PS: The boiler has been serviced twice by two different companies and they didn'f flag any concerns.

sorry , I cant help you, I could use that control for your heating, but it is not what it is designed to do so, I dont know what they have done to use it to control the Gas Boiler

It's not possible to replace the mechanical timer for a digital or RF equivalent?

it is possible but you cant use the same wiring, you can use the same wires but you will have to rewire your set up

Is the black a switch live?

Would it be possible to use a Thermostat such as a Siemens rdj100? I believe a link can go from live to common if I’m correct? and then just use the single output so to speak?

Thanks for that, what would I need to check to test this?
