Press the button again to switch to spa spillover operation ("SPILLOVER" LED illuminated). Pressing the "POOL/SPA/SPILLOVER" button again will switch back to pool-only mode. Note that the filter pump will turn off while the pool/spa valves are turning. Dual Equipment Pool and Spa systems without spa spillover: The POOL/SPA/SPILLOVER button has no function.

Press the POOL/SPA/SPILLOVER button again to return to the separate Pool and Spa loops mode of operation. Note that the Pool Filter pump will shut off while the pool/spa return valve is turning. The system will automatically switch out of spillover whenever the spa filter pump is turned on. NOTE: For Dual Equipment Pool and Spa systems, there is no Spa Only mode. Heaters This description applies to Heater1 and to Heater2, if programmed (note that the function of the Valve4 button changes to Heater2 when Heater2 is enabled). Pressing the "HEATER" button causes the Aqua Plus 16v to switch the heater control output between a "forced off" state and a normal, automatic thermostatic control operating state. System Off Each remote display/keypad has a red "SYSTEM OFF" button on the upper left corner of the keypad. Pressing this button will turn all outputs off and they will remain off, regardless of any programmed control logic, until either the "SYSTEM OFF" button (on any remote display/keypad) is pressed again or the "SERVICE" button is pressed on the display/keypad at the main unit. The red "SYSTEM OFF" LED will illuminate to indicate that all outputs and being forced off. ! WARNING: pressing the "SYSTEM OFF" button overrides any programmed freeze protection and may cause damage to your system in freezing conditions. Service The main unit keypad has a "SERVICE" key. This button is used primarily during servicing of the pool equipment. If you want to completely disable the automatic operation and operate the system manually, you can put the system into Service or Service-Timed mode by pressing the "SERVICE" button. Pressing the "SERVICE" button once will switch the system into service mode which means that all automatic functions are disabled, and the remote display/keypads are disabled (except for manual turn off for emergencies). The red "SERVICE" LED will be illuminated and the Aqua Plus 16v will remain in this mode of operation until manually taken out of service mode. Pressing the "SERVICE" button again will cause the Aqua Plus 16v to switch to service-timed mode which is very similar to service mode, except that the Aqua Plus 16v will automatically return to normal operation after 3 hours. During service timed operation, the "SERVICE" LED will flash and the time remaining will be displayed on the remote display keypad(s). Pressing the "SERVICE" button again, will return the Aqua Plus 16v to normal (automatic) operation. See Troubleshooting/Diagnostic Information for more information about the service modes. 5
