The present invention relates to a control circuit for a whirlpool bath or pool. The control circuit is used to deliver water and/or air to outlet jets in a water-filled pool such as is typically used for hydrotherapy massage. The control circuit includes a pool with a water compartment, a plurality of air jets and water jets in the pool and in communication with the compartment. A water pump connects to the water jets. A rotary valve is interposed between the water pump and the water jets. The rotary valve can be rotationally operated to sequentially provide water to the water jets. Thus, a pattern or a wave can be established from the water jets. An air pump is also provided and connected to the air jets by a manifold and a three-way valve. The manifold is connected to the water jets by a plurality of conduits. Check valves are provided to prevent water from getting into the air system. The three-way valve allows air to be supplied and drawn into the water jets by venturi action.
