Spa system with flow control feature
First Claim
1. A control system for a bathing unit, the bathing unit including a receptacle for holding water, the receptacle having at least one outlet port and at least one inlet port, said control system comprising:
- a) a circulation system through which water can flow between the outlet port and the inlet port of the receptacle;
b) a jetting pump assembly suitable for pumping water through said circulation system, said jetting pump assembly having a motor driving a pump, the motor being configured for operating at a plurality of different motor speeds within a range of possible motor speeds;
c) a controller in communication with said jetting pump assembly, said controller having;
i) a memory unit; and
ii) a user interface configured for;
1. enabling a human operator of the bathing unit to specify a set of parameters to create a user configured jetting mode and to store the user configured jetting mode in the memory unit for later recall, wherein the user interface enables the human operator to independently specify a particular first motor speed and a particular second motor speed when creating the user configured jetting mode; and
2. allowing selection of a jetting mode amongst jetting modes stored in the memory unit, the jetting modes stored in the memory unit including the user configured jetting mode and at least one other jetting mode;
said controller being responsive to the selection of the user configured jetting mode from the memory unit via the user interface for causing the motor driving the pump of the jetting assembly to vary its speed based in part on the specified particular first motor speed and the specified particular second motor speed.

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.
