Example: If the heat pump system is used to heat up one floor where all the rooms
have the same heat emitters.
If you are heating up rooms with underfloor heating or radiators, a very common
way is to control the temperature of the main room by using a thermostat (this can
either be the dedicated Human Comfort Interface (BRC1HHDA) or an external
room thermostat), while the other rooms are controlled by so-called thermostatic
valves, which open or close depending on the room temperature.
