Hello. I am a new user of a Samba 4.3. I recently bought a brewing system and it came pre-loaded with a brewing program on a Samba SM43-J-TA22. I am interested in learning Visilogic and writing a simple program to control a water solenoid by temperature for my fermenter. Can the Samba operate two distinct programs at different times? Example: I power it up and have an option of what program I want to operate. Or, do I need to add to the existing program? I am in no rush to get this completed as I want to take my time and slowly learn the basics of Visilogic. Thanks!
