Ferroli Modena 32c HE, changing from manual to heating controls

[CFergie]

boiler was controlled using +&- buttons on pcb display for CH, HW was on demand. Now want to control it using thermostats that control valves through the auxiliary connections on pcb.
Is there any links inside boiler that need removed?

Not a diy job, get a gsr and stop pillocking about with something you're neither competent nor qualified to work on.
