Is there a way in the Logic to Increase or Decrease the value of a system IO. I understand how to do it with a Button use nudge up and nudge down, but just wondering how it would be done in the code. [CODE]once (GetCBusState("Local Network", "Pumps & Lights", "Test Control") = ON) then begin //(This is where i want to decrease the system IO by 1 understand i can set it to what ever number i want but how to decrease it) SetIntSystemIO("Floor Heat Days Select",1); end;[/CODE]
