1. A method for controlling an under surface hydronic heating/cooling system for heating/cooling a plurality of rooms in which liquid is led along a main supply pipe to a supply manifold and distributed in the manifold into under surface heating loops, the under surface heating loops returning to a return manifold, and at least one of the manifolds having actuators for controlling the flow in the under surface heating loops, the method comprising:
providing at least one under surface heating loop of said under surface heating loops in each of said plurality of rooms to heat/cool said rooms, modulating a duration of a duty cycle in each said under surface heating loop such that during a duty cycle for each under surface heating loop a flow is on and between duty cycles for each under surface heating loop the flow is off, making at least one of said under surface heating loops in one of said rooms to be a bypass loop, monitoring the actuators in the under surface heating loops, including determining whether the actuators for each of the under surface heating loops is in the open or closed position, and causing the actuator of the bypass loop to be in the open position when the actuators for all of the other under surface heating loops, other than the bypass loop, are in the closed position and causing the actuator of the bypass loop to remain in the open position until at least one of the actuators of the other under surface heating loops is opened. |
