Aqua Plus 16v Control Power
The Aqua Plus 16v requires 120VAC, 2A power to operate the control logic circuits and the chlorinator. This
power should be connected to one of the circuit breakers.
!
WARNING: 120VAC only (permanent damage if connected to 240V)
High Voltage (120/240V) Pool Equipment
All Aqua Plus 16v relays are double pole (they make/break both “legs” of 240V circuits) and are rated at 3HP/
30A at 240V (1½HP/30A at 120V). Refer to the diagram below for typical relay wiring.
!
WARNING: Do not use the Aqua Plus 16v to control an automatic pool cover. Swim-
mers may become entrapped underneath the cover.

For a Pool/Spa Setup selection of “Pool Only”, “Spa Only” or “Pool and Spa-Std”, Heater1 and/or
Heater2 will keep the filter pump running. For “Pool and Spa-Dual”, Heater1 will keep the spa filter
running and Heater2 will keep the pool filter running.
Allow Low Speed
This menu only appears if the filter is configured for 2-speed operation. During default operation,
high speed mode is used whenever the heater is on. If Allow Low Speed is enabled, low speed will be
allowed even if the heater is on.
Minimum Speed
This menu only appears if the filter is configured for variable speed operation. This is the minimum
speed the pump will run at when the heater is on. The selection is from Filter Lowest to Filter Highest
speed.
Heater2 is Heatpump
This menu appears in the Heater2 configuration menu if Heater2 is enabled. If set to “Yes”, Heater2
will only be allowed to be on if the Air Temperature is > 50°F. Also, two new menus, Spa Heater2
Priority and Pool Heater2 Priority, will appear in the Settings Menu. Refer to the Settings Menu for
more information on these new menus.

Solar
The Solar configuration menu will
NOT
appear if “Pool and Spa - Dual” has been selected in the Pool/
Spa setup menu. If the solar control logic is “Enabled”, several additional steps must be taken to
ensure proper operation of the solar heating system. If the solar is operated by a valve, then a valve
(Valve3 or Valve4) output must be setup for solar logic (page 37). If the solar is operated by a pump,
then one of the AUX relays must be set up for solar logic (page 34). Also, the “solar” temperature
sensor must be installed. This sensor is typically mounted near the collector array and is used to
sense whether sufficient solar heat is available.
If solar is “Enabled”, the valve or solar pump relay will turn on when the water temperature is less than
the desired temperature setting AND the solar sensor is hotter than the water by at least 8ºF. The
desired temperature is in the “Settings Menu”. If applicable, the homeowner will be prompted to enter
separate pool and spa desired temperature settings. Depending on the position of the pool/spa
suction valve, the proper temperature setting will be used.
Solar Extend
If “Enabled”, the filter extend logic keeps the filter pump running beyond the normal turn-off time if
solar heat is still available. When solar heat is no longer available, both the solar valve/pump and filter
pump will turn off simultaneously. Solar extend will NOT cause the filter pump to turn on, it will only
delay the turn off time when solar is operating.
Solar Priority
If both “Solar Control” and “Heater Control” are enabled, the Solar Priority feature will keep the
conventional heater off whenever solar heat is available. This provides the most cost effective way of
heating the pool. When solar heat is not available, the conventional heater will operate normally.
