I'm replacing my single speed 1.5 hp motor with a 2-speed 1 hp motor (B2982). Single speed is currently turned on and off with mechanical timer, something similar to this one. Do I need a SPDT switch or can I use that timer to use either Hi or Low? I no longer need to control my booster pump since I no longer use a pressure pool cleaner.
If I can use the timer to switch the motor, is there an "ideal" run cycle? Like 1 hour on high, 7 hours on low... if I use a switch can it just be on low 8-10 hrs? Only using high for backwashing and initial pump prime.
