help ... New to all this.
set up smart control valves on both rads in big attic space ... seems to think they are each in separate room .. how do I combine and make one of them the master ?
Give both devices the exact same room name in "Rooms & Devices" and then click on the room (not a device) and you should have the option to change the measuring device.
Strongly recommend having each SRT in the horizontal plane to minimise temp inaccuracies due to varying effects of radiant heat from the radiator.
