SPA SYSTEM WITH FLOW CONTROL FEATURE
First Claim
1. A spa system comprising:
- a. a tub for holding water, said tub having at least one outlet port and at least one inlet port;
b. a circulation system having a pump assembly to circulate water from said outlet port to said inlet port, said pump assembly including a BLDC motor and a pump, said BLDC motor coupled to and driving said pump;
c. a controller coupled to said BLDC motor to control the speed of said BLDC motor in response to a user input, wherein the speed of said BLDC motor can be set to any speed within the speed range of said BLDC motor to adjust the flow rate of the water discharged from said pump to said tub through said inlet port.

Abstract
A spa system comprising a tub, a circulation system and a controller is provided. The tub holds water and has an outlet port and an inlet port. The circulation system has a pump assembly, including a motor driving a pump, to circulate water from the outlet port to the inlet port. The speed of the motor can be set at different speeds by the controller in response to user inputs to adjust the flow rate of the water discharged into the tub through the inlet port. Alternatively, or in addition, the speed of the motor can be set at different speeds by the controller depending one whether a water heater positioned in fluid communication with the pump assembly is in a heating mode or in a non-heating mode. In some implementations, the motor used to drive the pump is a BLDC motor.

9. A spa system comprising:
-
a. a tub for holding water, said tub having at least one outlet port and at least one inlet port; b. a circulation system for circulating water from said at least one outlet port to said at least one inlet port, said circulation system having; i. a pump assembly including a motor and a pump, said motor being coupled to and driving said pump; ii. a heater in fluid communication with said pump assembly to heat water circulating from said outlet port to said inlet port of said tub; iii. wherein said motor operates at a first speed when said heater is activated to heat the water circulating, wherein said motor operates at a second speed different from said first speed when said heater is not activated to heat the water circulating. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
