P933 Date Format 
This parameter allows you to alter the format that the date is displayed to 
your choice of DD: MM: YY, MM: DD: YY or YY: MM: DD. The default 
is MM: DD: YY. 
LED Colour 
Each relay has an associated LED, located on the unit’s front panel, which 
indicates the status of the relay. By default, the LED of any relay that has 
been  programmed  but  is  in  its  “OFF”  state  will  be  illuminated  ‘yellow’. 
When “ON” alarm relays will cause the LED to illuminate Red and pump, 
control and miscellaneous relays will cause the LED to illuminate green. 
LED’s of any relays that have not been programmed will not be illuminated. 
Customised  settings  for the colour  of LED’s  can be achieved  by using  the 
following parameters.
