Just a short follow-up since you quoted me, the Hammerhead solenoid will fire even in OC mode if the loop PO2 falls below .19. This is one of the saftey protocols built-in I feel this method is an acceptable solution to "turning off" the solenoid once out of the water.
I have been using this approach for the last year and it works well...
