Balboa error codes

These messages are quoted from Balboa Water Group user guide 40985-G, dated 26 March 2014. It covers system models BP2500 and BP2600, software 5.0 and later, with a TP900 panel (software 2.0 or later) or a TP800 panel (software 1.9 or later). The guide calls the numbers Message Codes, such as M016. It does not print the short letters dr, Pr, or EC, so those letters are not given a meaning here. A message with no M-code in this guide is not a separate page.
