Ok so I installed a new/used Watkins 5002 circ pump yesterday in my spa and it works great, but the spa now gets way to hot (around 115F) when I checked it and turned it off when I turn the thermostat knob you can here the relay clicking iv tried to let it sit un-powered for an hour or so and turn it back on the but the pump immediately goes into its second speed as if it need to heat up the pool more but the pool is still really hot. Any help will be greatly appreciated.
