I have a new inground pool install underway. I have a hayward 1.5hp super pump dual speed and need to know what kind of timer to go with it that will automatically switch between high and low. I guess another question is do I need the timer to control this or can I just manually switch speeds when needed. I will also have a SWG and is there anything special that needs to be considered with the dual speed pump. I will have a single speed pump for the pool cleaner. Any suggestions are much appreciated.
