Hi Mad,
I'm working on two houses in QT at the moment.
We have a proper BMS setup to control UFH, Gas Boilers, HWHP, Radiators and a VRV system.
The system alows for weather compensation depending on o/s temperature and infrared radiation. The system controls the water temperature for UFH and Radiators and is also linked to the VRV system to offset the room sensor readings on days with lots of sunshine and low o/s temperature.
Haven't seen this in a domestic install yet though.
