I'm in the process of adding automation (Intellicenter) to an older pool/spa combo. The spa has a spillway about 1" above the pool and historically, I keep the multi-port valve splitting the pool return and the spa jets just slightly open to the spa jets so the spillway operates 8 hours a day. I have just two valves currently: 1.) suction from pool skimmer/main drain and spa drain, 2.) return to pool and spa jets. I would like to add a 3rd valve with an actuator so I can schedule a spillover mode for an hour a day but have full pool circulation the rest of the time. It seems with my current valves I can only adjust the return actuator cam stop to have spillover mode active all the time, never full return to pool.
Where does this 3rd valve go?
