Thanks for the reply, Could I run the tub on a timer so that the pump is only on for a set number of hours? If so, how long should it run?

I have an older Hot Spring Soveriegn spa and do not have the manual. Can anyone tell me how the control knob for the heater works. It has a number of hash marks before the hash marks with the numbers on the dial. I am hoping that there is a setting which will run the recirc pump for a certain amount of time each day. Thanks
