Hello all I’m a new member and wanted to give installing hive heating and water plus a multi zone unit myself a go. I currently have a range tribune he cylinder, ideal icos he24 boiler, 2 x Honeywell t40 thermostats on each floor and a Danfoss CP715Si programmer. Looking at the hive install manual it seems my set up is a bit more complex then a straight swap as there are multiple wires into each connector at the programmer end and tonnes of wires at the cylinder - I guess this is due to the various zones. I’ve had a look at the wiring document for the programmer, thermo and cylinder and kind of understand what each cable does. I was wondering if anybody had carried out an install on this system and how they went about disconnecting the thermostats (I read that terminating the wires behind the wall is a big no no and wanted to keep the cables in place but disconnect them safely) and how to identify what cable does what. I have attached pics of each component in my set up. Any advise is appreciated. Thank you all. P.s if I have left out any obvious details please let me know and I will provide more info.
