Pool recirculation control system
First Claim
1. A control system for a pool recirculation system having a pump for withdrawing water from a pool and for returning water to the pool, said control system including in combination:
- a temperature sensor providing a signal representative of the temperature of water withdrawn by said pump from said pool; and
a timer for periodically initiating operation of said pump at pre-established time intervals;
a controller coupled with said pump and coupled to receive said signal from said temperature sensor to operate said pump for different predetermined periods of time after operation has been initiated by said timer, the lengths of which are predetermined periods of time determined by said signal from said temperature sensor.

Abstract
A control system is disclosed for a swimming pool or a spa recirculating system. Water is withdrawn from a pool or spa by a pump and supplied, through a filter, back to the pool. As is common with such systems, a controller is operated to initiate operation of the pump at pre-established time intervals (for example, once every twenty-four hours). The length of time or duty cycle that the pump is operated at each of these time intervals is determined by a temperature sensor which senses the water temperature. The temperature sensor supplies a signal to the controller to cause the pump to be operated for a longer period of time when the water temperature is above a threshold temperature, and to be operated for a shorter period of time when the water temperature is below the predetermined threshold.

10. A method for controlling the operation of a pool recirculation system having a pump which is operated to withdraw water from a pool and for returning water to the pool, said method including in combination:
-
establishing a periodic cycle for turning on said pump; sensing the temperature of the water withdrawn from the pool; and operating said pump for different predetermined periods of time, the lengths of which are determined by the sensed temperature of the water withdrawn from said pool. - View Dependent Claims (11)
