Abstract

Times of at least one of on cycles and off cycles of a pump operating in one of a sub-pump mode and a continuous pumping mode are monitored. A determination is made as to whether to switch the pump from the one of the sub-pump mode and the continuous pumping mode to the other of the sub-pump mode and the continuous pumping mode based upon the monitored times of the at least one of the on cycles and the off cycles of the pump. The pump is switched to the other of the sub-pump mode and the continuous pumping mode in response to determining to switch the pump from the one of the sub-pump mode and the continuous pumping mode to the other of the sub-pump mode and the continuous pumping mode.
