Designed as part of the I-Wave system and for aftermarket and retro-fit applications, the Intermatic P1353ME pool/spa 3-circuit clock can be installed into almost any Intermatic enclosure and has the ability to program up to three circuits. Choose between six preprogrammed modes of operation, which include single speed pump or 2-speed pump/cleaner pump combinations. In addition, programmed modes that include auxiliaries can control pumps up to three horsepower 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. The circuit clock features freeze and heater protection, and includes the circuit clock only.
