I think that's a general feature of the pool equipment manufacturing industry - "why would you ever want to fix it yourself?!? Just call in a pool professional..." Pentair is no better in this regard - not only do they completely void their warranties for self-installation (60-days only), but all of their equipment is designed to keep a pool owner from figuring out what's wrong rather than helping them. For example - the IntelliChlor SWG relays no system information to the user other than salinity readout and, even then, you can only get that info easily through an automation panel. The front controller on the cell uses an archaic set of various push-button sequences to flash the LEDs in a Morse-code pattern to relay some basic state info BUT ONLY if you know what the pattern of flashes means (none of that information is available to the end-user). Finally, you can get no information about the voltage, current, temperature or run-time of the cell without buying a specialized RF probe that hooks up to a laptop USB port (it's called the "IntelliWand"). So, even though my $80 HP printer has both Bluetooth and a wireless IP access point for connection to an App that gives full state information of the system, most of these equipment manufacturers can't seem to figure out technological advancement beyond the 1990's....it's sad really.
