Hi i am looking to fit a wifi programmable room stat to my worcester bosch 35he plus. it looks as if one of the most common choices is the siemens rdj10rf but the instructions look to be a bit confusing according to some of the other threads, and it also looks of a lower quality than others as it has a slider selection switch as opposed to a digital menu? i have also read that some favour the honeywell cm921/7 controllers, and looking on their web sit it does seem to be better built and easier to understand the installation. Having said this the installation at the boiler end seems confused according to other posts. where do these controller wire into on the boiler? ive looked and it would appear everyone refers to the main power in block as to the point of wiring in for these systems is this right? do you double up the cables in live and neutral and take the link out of ls and lr and wire the controller to this?
any help?????
