Abstract

The present invention relate to a heating and/or cooling system with a fluid circuit including a fluid inlet line and fluid outlet line connected to a heat exchanger, a temperature sensor measuring a fluid temperature T, wherein the fluid inlet or outlet line includes a first valve and a second valve positioned in respectively a first and second parallel sub-lines forming a split section, and where the first and second valves are controlled according to input from a controller and operating with first V1 and second V2 valve openings respectively, where said controller is adapted to operate according to maintain said measured fluid temperature T to be within a normal temperature span, defined as a minimum temperature T1min and a maximum temperature T1max, by changing settings of said first and second valves, where the controller is adapted to change the valve opening V1 of the first valve in response to the measured temperature T, and to change the valve opening V2 of the second valve in response to the first valve opening V1 gets above a maximum opening V1max or below a minimum opening V1min.The present invention further relates to the method operating such valves.
