Manual System Operation
While the main objective of the Aqua Plus is to automate the operation of your pool/spa system, there may be
certain times when you want to override the automatic operation and control the equipment manually. To operate
the pool equipment manually while keeping the automation active, perform the following procedures. Note that if
you turn a relay on manually, it will remain on until either you turn it off manually, or the next time the programmed
automatic operation would normally turn that relay off. Example: the filter pump is programmed to run from 9:00A
to 5:00P daily. If you turn the filter pump on manually at 8:00PM, it will run continuously until the next day at
5:00PM at which time it will turn off and follow the normal program from then on. Manually turning off a relay
works in a similar fashion.
Filter Pump
Single Speed Filter Pump:
If the pump is currently off, press the FILTER button to turn on the pump. Pressing the
FILTER button again will turn off the pump. However, if there is a heater in the system, and it is operating, and the
“Heater Cooldown” feature is enabled (Configuration Menu) then: when you press the FILTER button to turn off
the filter, only the heater will turn off, the Filter LED will flash and the display will indicate “Heater Cooldown”. At
this point the filter pump will automatically turn off after 5 minutes of heater cooldown operation. If you want to
override the heater cooldown, simply press the FILTER button again to turn off the filter pump.
Two Speed or Variable Speed Filter Pump:
If the pump is currently off, simply press the “FILTER” button to turn
on high speed operation of the filter pump. The “Filter” LED will illuminate continuously. Pressing the “FILTER”
button again will switch to low speed operation and the “FILTER” LED will flash. Note that if the pump has been off
for more than 30 seconds, it will run at high(est) speed for 3 minutes regardless of selection. This high speed
operation helps allow the pump to prime and establish normal water flow.
Freeze Protection:
This function protects the pool, plumbing, and equipment against freeze damage. If Freeze
Protection is enabled and the AIR temperature sensor falls below the preset freeze protection temperature (see
Filter Configuration), the Aqua Plus will turn on the filter pump to circulate the water.
External Input Interlock:
If enabled, this function will force the filter pump off when the external input is active. External Input Interlock will
have precedence over Freeze Protection for Filter output.

Diagnostic Menu
To enter the Diagnostic Menu, press the “Menu” button repeatedly until the display shows “Diagnostic
Menu”. At this point, you can use either the “<” or “>” buttons to scroll through the various menu items
which are described below:
Set Day and Time
Wednesday 10:37P
Move to previous/next menu item
+23.45 +6.75A
84°F 3200PPM
Press to switch chlorinator operation to opposite polarity (15 second delay)
+/- 23.45V is the voltage applied to the chlorinator cell
+/-6.75A is the current (amps) through the cell
84ºF is the water temperature at the cell
3200PPM is the “instant” salt level at this time
This display will be shown only if the chlorinator is enabled.
For the chlorinator to be
operating, several other things must be happening: the filter pump must be running, the flow
switch must be detecting flow, the chlorinator setting must be set greater than 0%, the water
temperature at the cell must be between 50ºF and 140ºF, and the salt level must be within the
operating range. If any of these conditions are not met, the chlorinator diagnostic display
will tell you the reason. It’s possible to have more than one reason, in which case after you
rectify what was displayed the first time, a second display will appear.
If the current (amps) display is 0.00A, then the chlorinator is operating normally but is in the
off part of its normal operating cycle. Simply press either the “+” or “-“ key to start a new
cycle.
The Aqua Plus periodically reverses the polarity of the voltage applied to the cell in order to
automatically clean off any calcium deposits. It is important that you check the chlorinator
operation in both polarities. To do this, press either the “+” or “-“ buttons and the chlorinator
will turn off, wait for 15 seconds and then turn on in the opposite polarity.
If a conventional or solar heater is operating, it is likely that the temperature of the water at
the cell is higher than the pool/spa water temperature displayed on the Aqua Plus default
display.
Instant Salt
3200 PPM (+=save)
Move to previous/next menu item
Press to load the “Instant Salt” into the averaged salt display
This display will be shown only if the chlorinator is enabled.
This display shows “Instant
Salt” or “Instant Minerals” (if Chlor. Config. is set for “Display Minerals”). The “Instant
Salt” is calculated based on the voltage, current (amps), and water temperature at the cell.
This is different than the “average salt” value which is displayed as part of the default menu.
There are a number of reasons why instant and average salt readings may differ. Some of
these include salt having just been added to the pool and not yet thoroughly mixed, calcium
buildup on the cell, and the cell aging.
pH 7.5 (On)
ORP 700 mV (On)
No function
Move to previous/next menu item
if AQL-CHEM is used
This display will be shown only if sensing is enabled.
This display shows both pH and ORP
levels/status when chemistry sensing is enabled via the Chemistry Configuration Wizard
(requires the use of AQL-CHEM Sensing Kit). The Aqua Plus will refer to these levels to
determine how much chlorine to generate (ORP) and, if using an AQL-CHEM2 dispense kit,
how much CO
2
or acid to dispense (pH). Refer to the AQL-CHEM manual for specific
information about these levels as well as the recommended ranges.
Flow Switch
Flow
No function
Move to previous/next menu item
This display will be shown only if the chlorinator is enabled.
The current status of the flow
switch is displayed. There is a short delay when transitioning from flow to no-flow and a
longer delay on the transition from no-flow to flow. The delay time is displayed.
