Abstract (en)

[origin: EP0924472A2] The method involves using an electronic control arrangement (20) to control at least one valve (9, 10) in an inlet conductor (7) of a fluid container (5) and a drive of a pressure pump (11) in response to a temporal course of a pressure change of a fluid in a circulation system. Different gas reduction processes are selected and activated, a fault notification is issued, and/or a switch-off of the system is initiated, in dependence on the determined pressure change. The method involves controlling a device for a gas reduction and, if necessary, pressure correction of a fluid in a circulation system, especially a heating system, having at least one fluid container exchanging at least occasionally gas with the atmosphere. The fluid container is connected with the circulation system over an inlet conductor containing at least one electrically controllable valve. A pressure pump is provided in parallel to the controllable valve, for feedback of the fluid from the fluid container. An Independent claim is provided for an arrangement implementing the method.
