Hi
Noted that you have managed to get more than 10 rooms to request heat from the boiler. If I am reading correctly you added a second controller to your system.
was that wired in parallel to the boiler so either controller can call for heat and therefore you’ve got 2 zone controllers on the same account?

I did similar setup as Rschot did by having two receivers controlling the same boiler and each receiver handles 7 rooms. I pre-wired the controllers 'in parallel' before connecting them to the power supply Neutral (N), Live (L), and to the boiler terminals Live (L) and Switched Live (SL). My combi boiler is expecting a simple ON/OFF switch capable of handling 230V for control, so the parallel wiring will work (when either one or both of the controllers call for heat, the boiler will be switched on). Of course, you will need to understand your existing wiring before following the same setup.
