[4]=Program Schedules
Use this function to set bell schedules. A schedule lists the days and times when the bell
circuits will turn on. Your Master can have up to eight (8) different bell schedules with up to
sixty-four (64) ‘events’ per schedule. If needed, you can make several schedules active at the
same time to increase the number of events to as many as 512 (8 multiplied by 64). In fact,
each ‘event’ can trigger several ‘actions’. For example, you can program a single event to turn
on relays #1, #2 and #4 for 7 seconds at 08:00 AM on Tuesdays, Thursdays and Holidays
