The Grundfos Comfort series circulation pump is particularly suitable for use in family homes or apartment units. The pump ensures the immediate supply of hot water without the need to "run off" a quantity of cold water from the pipes. This greatly contributes to user comfort. 

Operating Modes

• AUTOADAPT (factory set). For a detailed description of this function, see below.
• Temperature-controlled operation.
• Continuous operation.

Description of the AUTOADAPT Function

The Autoadapt function works on the principle of continuously determining the time periods during which hot water is drawn in a given household or house. Based on this information, the pump's electronics activate the pump only when there is a probability of hot water usage. It stores this data in its calendar, which it continuously updates, thus adjusting the pump's activation times. The stored records from the last two weeks are used. The calendar also distinguishes between weekdays and weekends. This method of regulation results in very high energy savings, especially compared to older types of circulation pumps.

The Autoadapt function ensures the disinfection of the system (elimination of Legionella bacteria) once a week by activating when the heat source significantly increases the water temperature.
