open zone?

Think about it its not rocket science..
Is zone seven used. If not then it needs to be linked out or programed out.More likely to be the latter with these modern day panels.

If the zone is used then suspect the wiring or what ever deviceis connected to the end of it. Simples

Getting too many of these now. If people don't give full information it is almost impossible to answer the question, as here.

eg panel type, what is connected to Z7

Why did you have to replace the control panel?

Has it worked since the panel was changed?

Any other information that would be relevant?
