Programming the 108 plus
General
The 108 PLUS controller contains two functionally identical channels on a single printed
circuit board (PCB), each having a program slide-switch and each being programmed
through its respective keypad. The instructions which follow describe the programming
of a single channel, however they apply to both channels independently.
The basic principle of programming is as follows:
L Move the slide switch on the controller PCB from ‘RUN’ to ‘PGM’.
L Enter a key sequence on the corresponding keypad.
L Observe both the red and green LEDs turn on for one second.
L When all functions are programmed return the slide-switch to ‘RUN’.
Programming the factory settings
This function will restore all codes, times and functions to the factory settings (see
Table 1 for the complete list).
This facility is useful for fault diagnosis. It makes use of the Test Button on the PCB
rather than the keypad (which may have been incorrectly installed).It is always
advisable to return to this condition whenever the unit appears to malfunction during
installation or following an unsuccessful programming session.
To program Factory Settings:
L Move slide switch to ‘PGM’
L Push the TEST button once.
L Observe the red and green LED turn on briefly.
L Move the slide switch to ‘RUN’.
