GRUNDFOS Grundfos Circulator Pump COMFORT 15-14 BA PM 1x230V Rp1/2 DACH – 99302331

COMFORT 15-14 B TA The COMFORT TA is an efficient circulating pump designed for hot water circulation 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, regardless of whether the system has mixing or control valves installed. The pump features a compact housing and a permanent magnet with an integrated control unit. The spherical rotor, equipped 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 features a built-in temperature sensor for maintaining water temperature. The user-friendly interface has LEDs and push buttons on the control panel. This provides an intuitive way to display 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 that 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 inactive periods such as holidays, saving energy and water by operating the pump only when necessary. After 24 hours without hot water usage, the pump automatically switches to holiday mode and resumes operation when hot water is required. In 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 provides immediate comfort regardless of the usage pattern when it detects a 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 a 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 measured temperature in the system. The maximum temperature of the system is constantly measured, allowing for dynamic adjustment of the 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 operating point to adapt to heat loss in a specific piping layout. {_BL_}67% reduction in heat loss compared to a continuously running pump. {_BL_}Low energy consumption and quiet operation. {_BL_}Compliance with pipe manufacturer flow rate 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 limescale 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, including 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 protection design that eliminates the need for an earthing cable. {_BL_}Insulation shells to reduce heat loss. {_BL_}Check 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 a permanent additional vent valve. {_BL_}Optional connections for pipe connections in various sizes and types. {_BL_}Optional check and shut-off valves are available.
