Technical Specifications of Grundfos 599388 Timer:
This timer was used to replace the eight year old timer which had begun "dragging" and was losing several minutes every day. The replacement timer came well packaged and was easy to install. After two weeks, it appears to be working perfectly. More importantly, we are able to get hot water immediately to the shower, which is a long way from the water heater.
