Circulation pump not working.

[Chef]

I have a 2002 Jacuzzi j340 that I bought used about a month ago.  The circ pump only runs when the heater comes on.  I have changed out the flow switch and installed a new circ pump. When I first turned on the hot tub after installing the new switch and pump it ran all the time now for some reason it only runs when I adjust the temp.  Please Help.

Here's the manual: http://www.spaparts123.net/Manuals/JacuzziSpaManuals.html

It looks like you can have the pump come on at certain intervals.
