Hi,
I've got an old Comfort I system. The main PCB has a chip labelled “Outside 4.169†A006166. The slave SEP modules have a chip labelled First 4.164. The SEP PCB is SM0223.
I've noticed that when arming or disarming the S12V connection on the SEP does not switch off, whereas it does on the main CPU. I suspect this might have always been happening. Both SEPs exhibit the same the problem, so I don't think it's a faulty PCB.
I found in the forum that there may be a jumper that needs removing (J7). I removed that, pressed the SEP reset button and tried again, but no luck. Have I got the right jumper?
I know it's a very old system but as it's functioning perfectly other than this, I'm reluctant to upgrade it.
Any ideas?
Kind regards,
Tim
