Variable controller for circulation systems
The purpose of a circulation system is to provide the consumer with hot water as quick as possible when opening the tap. The pipe line system for the supply of domestic water is simultaneously used as a circulation system so that by means of the circulation pump, water is passed through the water pipes even without having to open the tap. Via a flow switch in the cold water pipe, the unit monitors the water draw off. After opening the tap for a short moment, the circulation pump is switched on and will be switched off again due to the adjusted runtime. The tap operates like a “remote control“. This circulation pump control function is an eco-friendly and energy-saving solution in line with demand.
