ARRANGEMENT COMPRISING A GAS DELIVERY CONTROL SYSTEM AND A CENTRAL HEATING INSTALLATION AND GAS DELIVERY CONTROL METHOD.

摘要

An arrangement is disclosed of a gas delivery control system (1) and one or more appliances (AP) including a central heating installation. The one or more appliances are arranged for generating a request signal (S1) indicative for a requested supply of gas by at least one of the appliances. The gas delivery control system comprises, - a controllable gas valve (10) having an input (12) to be coupled to a gas supply (GS) via a conduit (22) and having an output (14), - a control device (30) for controlling the controllable valve, wherein the control device controls the controllable valve in accordance with a value of the request signal of the one or more appliances coupled to the output of the valve via a conduit, - a gas pressure sensor (40) for determining whether the gas pressure in the conduit has a value lower than a pressure reference value, - a reference module (50) for determining whether a predetermined time interval has lapsed since a closure of the controllable gas valve, - an error signaling module (60) for issuing an error signal (Error) if it is detected before a lapse of the predetermined time interval that the gas pressure is lower than the pressure reference value.
