Controller overview
The Matrix Maxi controller is designed to be intuitive to use and allows functions and
alarms to be set by the installer/user. It also allows faults to be monitored and logged to
enable easier system fault diagnosis.
The functions are set using the 4 buttons (A, B, C & D) on the front of the controller and
with the help of on screen prompts via the back lit LCD display. On the front of the
Matrix Maxi a green ‘power on’ light will be displayed whilst the unit is powered. If an
alarm or error is raised the red ‘Error’ light will be displayed.
