I have a Pentair MiniMax NT heater. About 2 weeks ago I had a lightning strike which blew my 24V transformer. I replaced it and now I do get 24V on the orange and white wires that plug in P4 to the panel. When I turned the heater back on it tonight it flashes "Err" fast for about 5 seconds and then all lights on the panel go out except the "PRESSURE SW" light (WATER PRESSURE SWITCH). This indicates flow I believe. Other than this light even the power light is out. I am hopeful someone can give some trouble shooting advice other than what the manual says: "NOTE: If Code ERR is shown on the LED display at any time, turn the heater off, (from power switch),then turn on the heater again. If the error code is still displayed, call a Pentair Service Technician".
I may try Pentair tomorrow as they did help me with the troubleshooting tocheck the transfomer but after it was dead I assumed I could take it from there to replace. Maybe something else is damaged from the power surge however nothing else has shown any change in operation. I have an Easytouch 8, 2 - 4x160 intelliflow's etc. I was home when the lightning happened and it really didn't seem like a big deal at the time. I just noticed my pump wasn't running the next morning even though the power lights were still on (the primary 4x160 that filters the pool). This pump is on the "control cable" from the Easytouch and it seemed like the communications was locked up. So after flipping the breaker a few times with no luck I disconnected the control cable, turned everything off and when powering up the Easytouch I did a system reset and the pump came on. Then I noticed the heater was out and called Pentair and they guy had me check voltage on the transfomer and it was bad.
Any ideas? :?:
