[5]=Schedule Changes 
 

If you wish to activate schedules at a future date, use Schedule Changes to program a 
schedule’s start date and time. This function works much like the Bell Schedule Function [4]. 
Enter your password (#0#), then press [#][5][#]  

 
   PROG.SCHEDULE 

CHANGE 

   SELECT 

[1]DATA ENTRY 

 

 

 

 

 

 

[2]DATA SCAN 

 

 

 

 

 

[3]DATA EDIT 

 

After making your choice, you will see  

PROG.SCHEDULE CHANGE 
EFF. DATE  : 00-00-00 
EFF. TIME  : 00:00 
NEW  SCHEDS:

 

 

Enter the date and time, then press the schedule number (1-8) for each schedule to activate at 
that date and time. You do not need to press [#] after you enter each value - only press [#] 
after entering the last New Schedule on line 4. 

 

After you enter each change, the menu gives you the chance to enter, scan or edit another one. 
Or, press [*] to quit. 

 

The Master will hold up to 16 programmed changes. Once your change occurs, your Master 
clears it from memory, making room for you to enter more changes. 

 
Note: Only the schedules entered in this function will activate at the Date and Time entered. Any 
schedules previously active will become deactive if not on the list of new schedules. 
 
 
 [6]=Enable or Disable Circuits 
 

This function requires the administrator password. 
 
Use this function to Enable and Disable your Master’s control relays during circuit wiring or 
maintenance. This function can also ‘hold back’ clocks to manually adjust for daylight savings 
in the fall if you have chosen not to use Function 7 “Daylight Savings”. 

 
[7]=Daylight Savings 
 

This function requires the administrator password.
