There is an electronic port connector on the control panel, WM part #640-000-003 of this unit (which I believe is a variant of a Honeywell control.) I have looked everywhere I can think of for information about this port which I think can be used to read-out the fault code history, but I can't find anything about it.
Does anybody have any info about this, such as the communication protocol, e.g. RS-232, CAN bus, etc., or what stored info may be available? Is there an available interface module? The company which installed the system, which is having intermittant problems has no such device, nor does the manufacturer's distributor representative/tech.
Thanks, Jemezbrad
