Method and means for controlling electrical distribution
First Claim
1. The method of controlling heating of a pool or spa body of liquid, that includesa) operating a pump and a pump motor, for circulating a stream of water to and from the body of water, the motor being an electric motor, b) transferring heat from the motor or from a separate heater, to the stream as it is circulated, c) monitoring the voltage level of electric power to be delivered or being delivered to the motor or heater, d) monitoring the temperature of water in said body of water in the spa or in the stream of water being circulated, e) providing a monitor or monitors operating to effect said monitoring, f) and controlling electrical power delivery to the motor or heater in response to said c) monitoring and/or said d) monitoring, while maintaining electrical power delivery to said monitor or monitors in the event of decrease of power delivery to the motor or heater below a predetermined threshold.

10. Apparatus for controlling heating of a pool or spa body of liquid or a stream of liquid flowing to or from the pool or spa, that includes, in combination:
-
a) a pump and a pump motor operating to circulate said stream of water to and from the body of water, the motor being an electric motor, b) transferring heat from the motor or from a separate heater to the stream as it is circulated, or to said body of water, c) first means for monitoring the voltage level of electric power to be delivered or being delivered to the motor, or heater, d) second means for monitoring the temperature of water in said body of water in the spa or in the stream of water be ing circulated, e) and third means for controlling electrical power delivery to the motor or heater in response to said c) monitoring and/or said d) monitoring, while maintaining electrical power delivery to said monitor or monitors in the event of decrease of power delivery to the motor or heater below a predetermined threshold. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

21. The method of controlling heating of a pool or spa body of water that includes:
-
a) providing and operating first components associated with controlling circulating of a stream of water to and from said body of water, and with controllable heating of said water, b) providing and operating second components associated with supply of electrical power to said first components, c) said second components, i) including a monitor or monitors operating to monitor the voltage level of electrical power supplied or to be supplied to said first components, and ii) also operating to monitor the temperature of said water, d) said second components operating to control said supply of power to the first components in response to said i) and ii) monitoring, e) controlling electrical power delivery to the components in response to said c) monitoring and/or said d) monitoring, while maintaining electrical power delivery to said monitor or monitors in the event of decrease of power delivery to the components below a predetermined threshold. - View Dependent Claims (22, 23)
