Grundfos adapting recirculating pump
Grundfos’ Comfort PM Auto residential circulating pumps feature Autoadapt, which learns the household’s consumption patterns and then adapts to it. The single phase, 115V pump motor yields up to 6.5 gal. per min. and uses two tempera-ture sensors: one within the pump and another connected by a cable installed in the hot-water flow pipe. When using the Autoadapt mode, average run times are 3 hr. per day. By continuously fine-tuning power consumption and flow rates to meet the dynamic needs of the system, this function saves both energy and money. Grundfos Pumps Corp.
