Abstract
A water circulating system, such as a spa system, is disclosed having a flow control feature. In one embodiment, the spa system includes a tub, a pump assembly and a controller. The pump assembly includes a BLDC motor and circulates water from the tub's outlet port to its inlet port. The controller sets the speed of the BLDC motor to any speed within the speed range of the BLDC motor in response to a user input to adjust the flow rate of the water to the inlet port of the tub. The spa system may also produce at least one jetting mode in response to a user input. The jetting mode may be a pulse mode, a sinusoidal mode, a ramp mode, or a saw-tooth mode. In another spa system, a first pump operates at a first speed to heat the circulating water when a heater is activated, and at a second speed when the heater is not activated. In other embodiments, the spa system includes a jetting pump assembly that includes a BLDC motor and a circulating pump assembly that operates at two speeds. In another embodiment, the spa system includes a circulating pump assembly that circulates water from an outlet port to an inlet port during standby. Where the circulating pump assembly operates at a first speed when a heater is activated to heat the circulating water, and at a second speed when the heater is not activated.
