build your programs, each with a schedule you choose, and assign zone run times for each program - if program A runs every day, and you only want zone 1 to run every day, then only zone 1 will have a run time on program A, and the run time for all the other zones on program A will be zero - if program B runs every other day, you set the program B run time for zone 1 to zero (since it already does what you want on program A)

remember that all the programs are in operation - you don't turn them on or off - you must program days of operation for each program you are using - you program start times for each program you are using - you are never actually commanding a certain zone to start at a certain time on a certain day, as those settings (start times and days of operation) apply to the programs
