Kesäkäyttölaitteisto lämmitysjärjestelmää varten

摘要

The invention concerns summer-operation equipment 1 for heat-piping systems wherein the circulation pump 5, 5' pumps water through a heat exchanger 4, 4' and where a valve 7, 7' on the heat-supply side is controlled by a regulator 12 and control motor 8, 8'. The system comprises also a measuring element 2, 2' which measures the outside temperature, a coupling device 13.1 which controls the circulation pump 5, 5' and control logic 24 which includes a timer for periodic operation of the circulation pump for short intervals when it would otherwise be stationary because of the control signal from the outside-temperature measuring element. This summer-operation equipment 1 has been created as a separate additional arrangement for connection to the regulator, which additional arrangement comprises: - casing - coupling device 13.1 and said control logic 24 which controls the said circulation pump, and - indicator 17 which is designed to show whether the ciculation pump 5, 5' is off or on.
