[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
