6 .15 Controller overview
The pressurisation unit 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 APU 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 .
A number of pressure set points can be set using the menus, these set points are
detailed below, 1 to 4 and in the description of the function .
HIGH ALARM SET VALUE (1)
SYSTEM PRESSURE SET VALUE (2)
DIFFERENTIAL SET VALUE (3)
LOW ALARM SET VALUE (4)
