Abstract
In a hydronic heating/cooling system, liquid is led along a main supply pipe (1) to a supply manifold (2) and distributed into heating loops (3). The heating loops (3) return to a return manifold (4). At least one of the manifolds (2, 4) has actuators (6) for controlling the flow in the heating loops (3). Actuators with fast operating times are used and valves of the actuators are controlled to close at different times in different heating loops (3).
