Set remote to “only open” gate

[SingerMartin]

Hi Sam,

Thank you for getting back to me on this. I've found the settings on the board but have not yet made the change.

Am I correct in thinking that the change you have proposed would mean that a button press would open the gates and they would remain open? I would like them to close after a time delay. But would also like it set such that a button press will only ever open the gates. 

Really appreciate your input, thanks again.

Mark

I also want to know this thing about the gates. 
Yes the work is must appriciatable.
