Brand new waterway 2speed pump fitted today but when I press jets button on topside panal I only get high speed or off ?? When pumps turn of I get HL .. switched the wires around and get low speed but not high any idea what it could be ... only buttons on topside panel it : jet , jets , temp and light... I must add that pressing the second jets button it turns the light on and when pressing the light button it highers the temp, temp button lowers temp and 1st jet button either turns on high speed or off ...
