compact
This system really gives you a lot, I like how compact it is and the amount of information it gives you. Been running well a few weeks, set at about 80% output to keep my 18k pool clean

plumbing system
Love the controls, but with all of the parts involved I thought the plumbing was much more complicated than it seemed like it was going to be.

Q: What should put the Percent at right now it's at 36?

Asked by: Tim - 8/15/2019
A: Tim, that is different for everybody! The % represents how hard the system will works to sanitize the water. Based on your pool size, pool use, environment, and water chemistry, your pool will need a unique amount of sanitization. The best advice would be to check your "Free Chlorine" level in the water - if it is too low turn the system up, and if it is too high turn the system down. Once you do that that a few times you can usually let it run for weeks on end or more before making seasonal adjustments. If you get a rain storm or a have a pool party, you typically want to use the system's temporary boost mode. Feel free to call us if the system is working well or is in need of replacement (866-766-5243).

Q: when adding salt the pool place said to turn off generator and keep pool pump runing how do i do that pool pump and the auto pilot is on time clock together

Asked by: jim - 1/21/2021
A: You would want to use the controls on the Digital Nano wall unit to turn it off. That way even if your time clock is still providing power to the salt system, the salt system is not trying to generate when there is an insufficient level of salt in the water. Its a best practice, but the salt system will turn on a warning light and won't be able to generate anyway until your salt level is high enough.

Q: Is this for a 220 power supply?

Asked by: Daniel - 5/18/2025
A: Per the owner's manual:

The AC input voltage of the Digital Nano/Nano+ has been preconfigured at the factory.
? Model numbers 75040, 75040-xx, 75042, and 75042-xx have been configured for 115 Vac.
? Model numbers 75041, 75041-xx, 75043 and 75043-xx have been factory configured for 230 Vac.
These voltage configurations can be changed in the field by a qualified electrician if required.
1) Refer to the wiring diagram located on the inside of the power center cover to reconfigure
the wires on the terminal block if the unit AC input voltage is going to be changed.
2) The fuse must be changed if the AC input is changed from the factory shipped
configuration::
? 230 Vac units require a 1 amp slow blow fuse.
? 115 Vac units require a 2 amp slow blow fuse.

The Autopilot Digital Nano Power Supply is a smaller moulded-plastic box with a backlit alpha-numeric LCD screen and keypad controls. It mounts on the wall (or nearby a post or support) by hanging the control box by a few keyholes on basic screws that have been secured in the wall. The digital display screen shows the  chosen percentage chlorine output and temperature. The keypad controls allow you to to raise and lower the chlorine output, enter the menu system, activate the boost (24 hours) or superboost (72 hours) mode. The menu system will display the current salinity, amount of salt needed to reach the ideal salinity level, and cell power diagnostics, 
The Autopilot Digital PPC2 Electrolytic Cell included with the Nano+ is a part of a raised manifold plumbing system (see pictures). The salt cell contains built-in titanium electrode plates and detachable power supply cord. The salt cell has threaded connections on the inlet and outlet, which allow quick access for service or winter removal (if applicable). Included with the cell in the manifold plumbing is a strainer, to catch any impurities that may have made it past the filter, and a bypass flow regulator, to divert only a portion of the water coming from the pump to go through the salt cell. Autopilot claims that this increases the chlorination efficiency.
The Autopilot Digital Nano+ comes with its patented bypass manifold (plumbing) system, with Tri-Sensor, Bypass Valve, in-line strainer, cell cord, and instruction manual.
