Programming the cn101a timer
CN101A programmable weekly digital timer
C = Master Clear, erases all program settings and current day/time.
C/R = Control/Reset, used to access programming mode and to clear individual programs.
You must press and hold this button for approximately 4 seconds to enter programming mode if there is a lower case "a" to the left of the time display. The system will revert back to active mode (with the lower case "a" to the left of the time display) after 30 seconds with no buttons pressed.
If this button is momentarily pressed while viewing a program, that program will be erased, but ONLY the On or Off program that is being viewed will be reset. The corresponding On or Off program in that cycle will NOT be reset.
Clock = In programming mode, this button is held depressed at the same time as one of the D+, H+, or M+ buttons to set the current day and time. When editing the programs, this button is used to exit when done.
P = Program select, each press will advance through the On and Off programs (presets). There are 16 On/Off cycles available (1 On, 1 Off, 2 On, 2 Off, ... 16 On, 16 Off).
D+ = Used to change the day when setting the time, or day(s) when changing a program.
When changing a program,
the following 15 different day combinations are available using the "D+" button.
MO; TU; WE; TH; FR; SA; SU; MO/WE/FR; TU/TH/SA; SA/SU; MO/TU/WE; TH/FR/SA; MO/TU/WE/TH/FR; MO/TU/WE/TH/FR/SA; MO/TU/WE/TH/FR/SA/SU.
H+ = used to change the hours when setting the time or a program.
M+ = used to change the minutes when setting the time or a program.
Manual = This button will cycle the output relay from AUTO to Manual OFF, back to AUTO, then to Manual ON, and finally back to AUTO. Programming mode must first be accessed using the C/R button to use the Manual feature. The manual On or Off settings will override all programs until switched back to AUTO.
There is a Lithium Ion battery which is intended to keep the clock going for up to 3 years during loss of external power, but the output relay will not work on internal battery power.
