I'm not sure about it.
In general, the CTM has some kind of memory regarding faults. Then it will block further activites for the next 1 or even 10 minutes, depending on the issue.
Normally the roof modules are only simulating the two buttons, that means, putting the respective wire to ground the way you do it manually.
