Designed as an upgrade to your T100 Series time switch, this Intermatic pool timer can be installed into almost any Intermatic enclosure and has the ability to program up to three circuits. Choose from seven pre-programmed modes of operation, which include single-speed pool pump or two-speed pump/cleaner pump combinations. In addition, progammed modes that include auxiliaries can control pumps up to 3 hp as well as underwater, landscape, and/or fountain lighting. Countdown and Override features allow cycle interruptions when pool/spa service is required. All timing and protection associated with filter pump/cleaner pump combinations and two-speed pumps has already been integrated into the software.
