System Overview
The Hayward Aqua Plus 16v is a multifunction pool controller used to fully manage your pool/spa system. The
Aqua Plus 16v can control pumps, valves, lighting, heaters, and chlorination. Although the Aqua Plus 16v is easy
to use, it is important to completely read through this operating manual before attempting to operate the control.
NOTE: This manual assumes that the Aqua Plus 16v has been wired and configured according to the Installation
Manual. Aspects of the Aqua Plus 16v that pertain to system setup are not covered in this manual.
Automation
The Aqua Plus 16v can control up to 8 high voltage (120/240V) pieces of equipment, up to 4 automatic valve
actuators, and 2 conventional heaters plus a solar heater. Both manual and automatic (programmed) operation are
available. All of the control functions can be programmed at a display/keypad which is part of the main unit
(typically located near the pool equipment) or at one or more remote display/keypads.
