The circulator also features a built-in digital timer, enabling efficient scheduling of the pump’s on/off hours, contributing to energy savings when hot water is not needed in the home. Here are the HWR models:
- 15-29 SF/T (flange, pictured here at the top of the post)

Notably, the toolless, removable power connector facilitates quick and easy installation. The circulator also integrates with Grundfos GO, providing the convenience of troubleshooting the system through the event log, running guided setup, setting custom control modes, and performing software updates. Moreover, the app offers historical trend data for flow, head, estimated media temperature, and on-cycle durations.
