My skimmer pump is controlled by the 1-10V interface, which I configured it to operate at Minimum during maintenance mode. This maintenance mode is for manual water change, which turn off the return pump, chiller and set the skimmer to run at minimum for 30 minutes. However, once this 30mins have passed, the skimmer pump immediately goes back to normal operation and because the sump is still full of water as the return pump just re-started, the skimmer cup will always be overflowed.
Is there a way that i can delay the skimmer pump to return to normal after the maintenance mode? Thanks.
