Control device for circulation in hot water circulation system supplied from cold water feed, has connection via signaling path to flow monitor that monitors state of cold water feed flow

摘要

The device has a controller (20) for connection via a control line (21) to a circulation pump (14) in the hot water system and via a signaling path (23) to a transducer. The transducer is a flow monitor (24) that monitors the state of the flow in the cold water feed (25). The flow monitor can be a turbine, paddle or floating body moved by the flowing water.
