Abstract
A method of controlling opening of a valve in an HVAC system is provided. The method includes controlling the opening of a six-way-valve according to a default control mode in dependence of a default sensor signal, the six-way-valve fluidicly coupling an inlet side and an outlet side of the heat exchanger alternatively with a first fluidic circuit in a first default control mode or a second fluidic circuit in a second default control mode; selecting a selected default control mode from the first default control mode and the alternative second default control mode; determining, while controlling the valve in the selected default control mode, whether the sensor signal is faulty; and switching, in case the signal is faulty, to controlling the opening according to a first fallback control mode or an alternative second fallback control mode, where the opening is controlled independently of the faulty sensor signal.
