i have managed to install firmware 5.11 and i have downloaded profliux controll 5.13. i am still experiencing error code when i click vortech pump 1 error code 41. the only reason i can think of is it is a new page not recognized by the vortech controller. the page on 5.10 just had basic timetable of vortech then description underneath. the new page on 5.13 has how you want pump to respond during awc, feed, maintenance
