HOUSE/290 version 2.0 is fully Year 2000 compliant.
The CP290 interface does not have any Year 2000 problems directly as it accepts the date in the form of weekdays only.
Reprogramming of the interface each week may be necessary also if series events are to be executed properly or when daylight savings time changes over. When HOUSE/290 is started, it checks to see if the DST dates are correct. If not, it will ask you if you want to adjust them. It will not make adjustments to the preprogrammed series events, you have to redo them manually. Depending on your application of HOUSE/290, you may be better off to disable DST and always use standard time. Make sure the computer is also set to standard time when accessing the interface.
