Abstract: A controller assembly allows an adjusted flow of water through a hydronic emitter in order to heat or cool an environmental entity. The controller assembly operates in two phases: a calibration phase and an operational phase. During the calibration phase, the controller assembly discovers a valve position where water starts to flow through the hydronic emitter based on signals from a temperature sensor and/or a sound sensor. The temperature sensor may be mounted in close proximity of the emitter inlet so that the controller assembly can detect when the temperature starts to change. The sound sensor may be mounted on the valve body to detect a rushing water sound that is associated with a start of the water flow. The discovered valve position is subsequently used by the controller assembly to adjust water flow between a minimum flow and a maximum flow.
