Cerbo GX Digital Input Delay

I have a hot water heater connected to relay 2 with the "Flame Out Sensor" connected to digital input 1. Every time the hot water heater starts I get an alarm. Can a delay 3 to 5 seconds be put on. If not can this be added in the future. This works great for a RV hot water heater.

If you have a multi you could trigger a digital input on the multi for the water heater ignition failure and use that with an assistant with time delay to trigger a relay from the multi to the digital input on the cerbo. It's more complicated I know but it would allow for a time delay and still have the alarm display on the cerbo and vrm. I intend to try the same on my system.

Thanks, I ordered a Multi today. Upgrading my Xantrex. So in a couple of days I'll try this. Again Thanks.

After sleeping on it I think there is a much simpler solution. I am assuming you used a relay to trigger the digital input. Just replace it with one of these.
