I am trying to switch from pool mode to spa mode via Aqualink RS6 pda. Pool Pump is on and when I press the spa mode it shuts down(delay) and both the Jandy valves do not move/switch. After a minute or so it starts back up, saying its in spa mode but still stuck in pool mode. I can manually move the valves via the switches and the switches are not in the center(off) positions, but to one side. The wiring looks good into the control unit.
