Abstract (en)
[origin: WO2020083453A1] District heating system, comprising a bypass situated between the inlet line and the return line from the heat exchanger and a flow valve situated in the bypass, wherein the flow valve is a flow control valve, which forms part of a flow regulation system of the district heating system, and wherein the flow regulation system comprises a first temperature sensor situated for measuring a temperature in the bypass, an electronic controller unit and a battery connected with the controller unit to power the operation of the controller unit, wherein the controller unit comprises means for wireless communication with a communication unit, wherefrom the controller unit can receive data and thereby be remote-controlled from the communication unit and can transmit data for remote logging to the communication unit, and wherein the controller unit is adapted as a slave unit, which is programmable for periodically after a first programmed time interval to prompt a command from the communication unit, which correspondingly can be adapted as a master unit, and for periodically after a second programmed time interval to transmit data to the communication unit. Methods for flow regulation and retrofitting of such a flow regulation system in a district heating system.
