I do have an evohome set which I explained to an electrician to install but I can not sort out one issue.
I have a pretty large living ( 90m2) and there are 7 actuators on underfloor heating valve. According to hce80 manual I have to divide the living to 4 different zones , meaning 4 different sensors . It sounds to me odd as I only want to use the evohome as the sole sensor and other zones ( which are actually same area ) act as per those instructions . Is that possible or do I really need 4 sensors in the living room .

Thanks and kindest regards,
