Which is master?

[Bloke]

Hi,

Had my Evohome fitted yesterday, one of the zones is a room with 2 radiators and a HR92 on each and another 2 zones are 2 rooms each, with HR92's on each (Had to do it this way as had reached the 12 zone max).

I understand that whichever HR92 in each zone was added first is the master, however I wasn't around when they were doing the binding and when asked which one was the master in each zone I got a bit of a puzzled look.

Is there any way for me to now go into some setting somewhere and find out which is the master and possibly change it to the other HR92 if it isn't the one I want?

Thanks,

Paul.

No way to tell... Just put one in the fridge (don't get it wet though) and see if the temp reduces, if it doesn't then its not the 'primary sensor'.

Thanks for the reply, I used a hairdrier
