GRUNDFOS Circulation Pump COMFORT 15-14 BA PM 1x230V Rp1/2 DACH

COMFORT 15-14 B TA The COMFORT TA is an efficient circulator pump designed for domestic hot water recirculation in residential buildings with a dedicated return pipe. It is compatible with all types of hot water tanks, instantaneous water heaters, solar or heat pump systems, whether the system has mixing or regulating valves installed. The pump features a compact casing and a permanent magnet with an integrated control unit. The spherical rotor, fitted with an impeller, ensures optimal functionality, supported by a robust single-bearing system. The drinking water-approved brass pump housing guarantees both safety and reliability. The COMFORT TA also incorporates a built-in temperature sensor for maintaining water temperature. The user-friendly interface features LEDs and push buttons on the control panel. This provides an intuitive way to view and set operating times and control modes, ensuring a comfortable and energy-efficient experience in the home. The COMFORT TA offers three control modes: AUTOADAPT, Temperature, and Continuous 24/7. With the AUTOADAPT control mode, the pump quickly learns usage patterns throughout the day, ensuring hot water is only available when needed via an external sensor on the supply pipe. The pump can therefore distinguish between morning, evening, weekdays, weekends, and periods of inactivity such as holidays, saving energy and water by operating the pump only when required. After 24 hours without hot water use, the pump automatically enters holiday mode and resumes operation when hot water is needed. For the first two weeks after installation, the pump frequently starts based on temperature control to ensure immediate comfort until the usage pattern is learned. The pump offers immediate comfort regardless of usage pattern when it detects hot water demand. Once a week, the pump performs a 15-minute disinfection cycle (anti-legionella). The water heater must activate this function once a week. The Temperature control mode integrates both external and internal sensors for more accurate measurement of water temperature and activates the pump when the water temperature falls below a certain level. The on/off temperatures are automatically adjusted based on the maximum temperature measured in the system. The maximum system temperature is constantly measured, allowing for dynamic adjustment of on/off temperatures. This mode also includes an automatic holiday mode for improved energy efficiency, making it ideal for holiday homes. Continuous 24/7 control mode The pump operates continuously 24 hours a day. The product offers: {_BL_}Q-H performance designed for single and multi-family homes, depending on the required duty point to match heat loss in a given pipe layout. {_BL_}Reduced heat loss by 67% compared to a continuously running pump. {_BL_}Low energy consumption and silent operation. {_BL_}Compliance with pipe manufacturers' flow velocity limits, including DN 15, DN 20 PEX, copper, and others. {_BL_}Drinking water approval, ensured by the brass pump housing, stainless steel rotor, and composite impeller. {_BL_}A design that makes it easy to clean scale and foreign deposits by removing the pump head, making the product meet unlimited water hardness requirements. {_BL_}Dry-running protection to prevent failures if the system runs out of water. {_BL_}Multiple installation positions, even with the pump head pointing downwards. {_BL_}A pump head that fits brass pump housings of old and new pumps of the same design, even from different pump manufacturers (such as WILO, VORTEX, LOWARA, DAB, and others). {_BL_}Easy electrical installation provided by a pre-assembled mains plug with a 1.5 m cable and a double-insulated protective design that eliminates the need for an earthing wire. {_BL_}Insulation shells to reduce heat loss. {_BL_}Non-return and shut-off valves included in the BX variant, reducing installation costs. {_BL_}An optional vent flange that provides an easy way to vent or drain the system without the need for an additional vent valve to be permanently installed. {_BL_}Optional connections for pipe fittings of various sizes and types. {_BL_}Optional non-return and shut-off valves are available.
