Hi there,

I have a large RO reservoir that I only want to refill if the low level sensor is activated. The high level sensor will cut power to the solenoid. This is the programming I currently have:

Fallback OFF
If ATO_lo OPEN Then ON
If ATO_hi CLOSED Then OFF

The issue I'm having is that whenever the water level in the reservoir drops below the ATO_hi sensor (anytime the ATO pump pumps enough water out), the solenoid kicks on and refills the bin. It's not waiting until the water level drops to the ATO_lo sensor. Is there some code I'm missing?

I'm using the newer MOS Optical Sensors from Neptune.

Defer 000:05 Then OFF
