Scott Pump Timer for Fountains, Aerators and Lights
The Scott Aerator Pump Timer runs your fountain, aerator or light set on a schedule, so your equipment only runs when you want it to. Every model is made by Intermatic and sold by Scott Aerator for its own 115V and 230V equipment. Pick the timer that matches your equipment voltage and how you want to install it.
• Five Options: 115V residential, 115V commercial, 230V residential, 230V commercial and the dual-voltage Intermatic Timing Center.
• Plug-In 115V Model: The 115V residential timer plugs into a GFCI-protected outlet, then your fountain, aerator or light set plugs into the timer.
• 40 Amp Commercial Ratings: The 115V commercial, 230V residential and 230V commercial timers are rated at 40 amps.
• Override Without Reprogramming: The commercial timers and the Timing Center have a manual override that leaves your program in place.
• Outdoor Ready: The 115V residential case is outdoor-grade plastic, the 230V residential timer uses a UL Type 3R outdoor enclosure and the Timing Center is outdoor-rated steel.
