Hello.  
Is it possible to create the schedule for master valve simmilar to zones?  
I need to start the pump well ahead of the first zone (example: the first zone should start at 5AM, but the pump has to start at 3AM). Will this device be able to achieve it?

Can I suggest something that may work. The master control operates when any zone is active. So don’t connect anything to Zone 1 but set the time to 3 am for 180 min. Zone 2 to 5 am. Etc The master control will start the pump at 3 am. I have not tested and I am assuming that you have enough Zones to spare one to do this. Other wise seperate timer.

My suggestion will not work as the M controller functions is on when the InkBird is in the ON state.  
I have just read the manual and it seems to fall short of explaining that the M controller connection is active when the InkBird controller is in the ON state.  
I have tested its function and confirm the above.  
Contrary to my previous understanding and exception which would be for the M output to only be active when a Zone is active.
