Guys, I am confused
I created a virtual outlet for maintenance, see picture.
I assigned it to the skimmer, waves and heaters, works
When i assign it to the return pomp outlet and set to auto it is shutting down the outlet why
Your pump output program is missing the Set ON command. Don't confuse Fallback ON with Set ON. Fallback only applies if the module loses communications with the Apex, such as when the AquaBus cable is disconnected, while the Apex is rebooting, or if the Apex locks up for some reason. The Set ON command is needed to tell the pump what to do if the If Maintenence line is false.
Change your code to this:
Fallback ON Set ON
If Output Maintenance = ON Then OFF
