On my EasyTouch 4, when it is operating in a filtration schedule and Solar is on, when I press Spa, the two valves fail to operate to divert the water to the integral spa instead of the pool. When the filtration/solar of off and I press Spa, these two valves transition as they are supposed to and all works fine. But when the pool filtration schedule is running and solar is on or off, I press Spa and the IntelleFlo pump changes speed, the solar valve transitions away from the solar panels, and the heater fires up - all as it's supposed to do. The only thing that doesn't happen, which should happen, if for the two valves to transition from pool to spa. So, instead of heating the spa, I'm heating the pool. Again, when the filtration system is off (pre- or post schedule) then pressing Spa does all of teh above plus transitioning these two valves so I'm heating the spa. Any ideas anyone?
