A controller and method for controlling the operation of electrically powered pool related apparatus in recreational pool system, and more particularly for controlling the flow of pool water through the pool system and water-conditioning apparatus, is disclosed. The controller includes a logic circuit formed with a plurality of logic gates coupled to pool-water-sensing apparatus and programmable input apparatus in accordance with a predetermined logic sequence. The pool system includes a swimming pool and spa, and the pool-water-conditioning apparatus includes a solar water heater and a non-solar water heater. The controller is capable of preferential solar heating and of temperature-switched operation, time-switched operation and a combination thereof, as well as manual switching.
