Light Timer Menu
You can use your Ozone XLM Series to turn your pool or garden lighting on and off
automatically, you can set the ON and OFF times using the light timer menu.
Press ENT to access the Ozone XLM Series Menu system. Press ENT again to select the
TIMER menu and then scroll down using the N/DOWN button until LIGHT MENU is
displayed on the LCD.
Line 2 on the LCD will now read "AUTO? Y/N". To enable automatic light operation press
the Y/UP-button. Line2 will read "Auto ON" for short period before displaying "ON hh:mm".
Adjust the ON time using the Y/UP and N/DOWN-buttons and confirm by pressing ENT.
The LCD will now prompt you to set the OFF-time, which is accomplished using the Y/UP
and N/DOWN-buttons as before. Press ENT-to confirm the new OFF-time and the LCD
will return to the home screen.
To disable automatic light operation, access the LIGHT menu in the way described above
and when asked "AUTO? Y/N" - press the N/DOWN button. Line 2 will read "Auto OFF" for
short period then the system will return to normal operation and the light can only be
operated manually (see below for how to do this).
Manual Light Operation
If the Ozone XLM Series is turned on, the light can be turned on or off manually by
pressing the Y/UP-button.
If you have multi-coloured LED lights that cycle through different colours and requiring a
power pulse to change effects, you can hold down the Y/UP-button to cycle through the
options and release when the desired colour or effect is achieved.
Controlling the Chlorine Residual
There are two ways of controlling the amount of chlorine entering the pool – by altering the
running times and by reducing the Ozone XLM Series Output. If the pool chlorine residual
tests high you can reduce the operating time and/or decrease the Output. If the chlorine
residual tests low and the output is already at maximum you will need to increase the
operating time and/or add supplementary chlorine.
Ozone XLM Series Output Control
Ozone does not form a residual in the pool, this is why it is running with a chlorinator. The
ozone system is on whenever the pump is on. The LCD display usually shows the amount
of chlorine being produced by the Cell as a percentage of its maximum.
However, this is the not the same as the Ozone XLM Series Output. The Output Control
turns the Cell ON/OFF over a short period of time. The Output setting determines how long
the ON time is – for example if the Output setting is 60% the Cell will be ON for 60% of the
period and OFF for 40% of the period. This is why the Cell will turn ON/OFF if the Ozone
XLM Series Output is below 100%.
