3.3 OWNER/OPERATOR CONTROL BUTTONS, CHECK SYSTEM LED, AND
AUDIO ALARM
The following is a brief explanation of owner or operator control buttons.
Please Note: This section assumes the installer has already programmed the system for specific site
parameters, has established proper water balance, and has pretreated water to 1 - 3 ppm (mg/L)
chlorine.
Attention Owner: Should Centigrade vs. Fahrenheit, choice of language, or other owner options require
modification, please refer to the programming information in section 7.6, located on page 23.
3.3.1 UP and DOWN Arrows
Use the UP and DOWN arrows to control the chlorine output level, then press the SELECT
button to save the value chosen. With a properly prepared pool, the recommended starting
output level is 50%.
Upon initial start-up, check sanitizer every 3-4 days and make small output level adjustments as
necessary to maintain 1 - 3 ppm (mg/L) free chlorine levels. Keep in mind, your Digital
Nano/Nano+ does not directly measure or regulate the sanitizer levels in your pool. Rather, the
owner / operator will need to periodically test the water to determine the current chlorine level,
and adjust the output setting as needed.
After the chlorine output level is “tuned in,” the unit will automatically make fine output
adjustments as the water temperature fluctuates. This temperature compensation feature will
adjust output depending on water temperature. See section 5.1 on page 10 for more information
concerning the Patented Temperature Compensation feature.
Please Note: The optimum output setting will vary based upon pool size, location, exposure to
sunlight, number of users, vegetation around the pool, water balance practices, and pump run
time. Your installer should have already taken these factors into consideration when performing
installation programming. Therefore, your adjustments, at this point, should be relatively minor.
3.3.2 The BOOST Button
The BOOST button increases output to 100%. Use this feature when a heavier than normal
bather load is anticipated.
Press BOOST once ............................. = 24 Hour Boost
Press and hold BOOST for 8 seconds . = 72 Hour Boost
Press BOOST a second time .............. = Deactivate Boost
3.3.3 MENU and SELECT Button
The “MENU” button allows the operator access to the “Test Pool Pilot”, “View setup”, “Owner
options”, “Maintenance” and “Installer” menus. (For full features of the Owner Options Menu,
please see page 23.)
Press the UP and DOWN arrows to scroll through the menus.
The “SELECT” button allows the operator to choose program menu options. The owner /
operator should not normally need to access these features on a regular basis.
Consult the Programming section on page 20 or contact factory customer support for additional
information.
A graphical overview of all the menus & sub-menus is shown in section 7.2 on page 19.
