Question - I cant see it can on the tech specs. The CBUS thermostat - cant it have an external temp. sensor wired into it rather than using the internal unit ? This is standard on most multi room systems - and certainly on mine. So, all my thermostat units are all centrally located, near all the electrics and CBUS relays, etc. with a wire (SFTP)going to a remote sensor in each room - all hidden. There's no need for the thermostats to be in the rooms on a multi zone system. There is a central touchpad in the hall where all the data is fed. Would be nice to replace these with CBUS h/w (and therefore tied into comfort etc). But if there's no remote sensor option, it's just not a viable option.
