Hey guys, im not a professional electrician, I just have a basic knowledge of some stuff.
In order for me to be able to explain what i want to do, I will first explain what is in place at the moment.
We have a 3 zone programmer which we never use as a programmer, we just turn on each zone manually when we want.
So i thought, since this is all done manually i could put together a raspberry pi connected to a 4 channel relay board and control the whole thing from my smartphone. I found all the software and hardware i need and i can make the relays open and close but I am not sure what to connect where on the relay in order to get the central heating to work as it works now.
Here is a picture of what the wires look like behind the programmer at the moment. The letters for the wires from left to right are: E,N,L,1,3,5
Here is a picture of the relay i have although the picture is of a 2 channel relay instead of 4 channel.
From my basic understanding, what i thought i should do is connect N and L together and then connect them to the COM terminal of the relays. Then connect 1,3,5 to the NO of each relay but I'm not really sure and I don't want to burn anything.
Can you please advise me on what to connect where?
Thank you in advance.
