Save on the Grundfos Digital Timer for Comfort System Pumps (99521972) at PlumbersStock. Comfort System is a very popular line of pumps, and traditionally, they've operated with analog timers. You will love your new digital timer, and how it's much easier to operate and program. The old pumps and timers are getting discontinued, so if you prefer those, get them while they're good. We recommend the digital option, tho. It also comes with a battery backup.
This timer is compatible with, but is not excluded to the following Grundfos pump part numbers: 99452454, 99452455, 99452457, 99452458, 99452460, 99452461, 99452473, 99452477, 99452459, 99452462, 99452478, and 99452479.
