Orp Menu - Pool Controls Ozone Chemigem User Manual

ORP (Chlorine Menu)
Accessing the ORP Menu
Access the Chemigem Menu System by pressing ENT. Use the Y/UP or N/DOWN button
to scroll through the main menu until ORP MENU is displayed on the LCD. Press ENT to
select.
Manual Feed
Having accessed the ORP menu, the LCD will ask "Manual Feed Y/N?". Press Y/UP to
select and (on solenoid valve models) the display will read "FEED 5 Sec/50mL". On
dosing pump models the display with read "FEED 5 mins/75mL"
You can increase the amount of the dose by pressing the Y/UP button until the desired
dose amount is displayed. (Note: the dose volume displayed is an estimate only)
Press ENT and (depending on which model you have) either the solenoid valve or the dose
pump will commence feeding liquid chlorine.
Adjusting the Set Point
The ORP Set Point is the value in millivolts that the Chemigem will adjust your pool water
to. You can adjust the ORP Set Point via the ORP Menu.
Enter the ORP Menu as described above and press the N/DOWN button when asked
whether you wish to do a manual feed and then again when asked if you wish to do a
superchlorination (not all units). The LCD will then read "ADJUST SET POINT Y/N?"
Press Y/UP to select this option and then the LCD will display the current set point. Adjust
this using the Y/UP or N/DOWN buttons. Confirm the adjusted set point by pressing ENT.
The new set point will then be displayed on the right-hand side of line 3 of the LCD.
SWC (AUX) Settings – for control of a Saltwater Chlorinator
The SWC (AUX) is off by default. To turn it ON simply press Y/UP. You will then be
prompted to keep the chlorine dose pump ON too. If you only require the SWC unit to be
enabled press N/DOWN to disable the automatic chlorine dosing pump – note that it is still
available for manual dosing. Otherwise press Y/UP to allow automation of both systems.
There is a Delay value that can be adjusted from 0 to 60 minutes (default 30 minutes) –
this delays the activation of the dose pump for a period after the unit starts.
When both systems are enabled the chlorine dosing is designed to only dose after the
delay period and when the ORP has fallen far below the set point. This means that the
chemical dosing will occur at times of high demand or very low residual.
Adjust ORP Control On or Off
To disable the ORP System (or re-enable it if it has been disabled) you need to access the
ORP menu and work your way through the MANUAL FEED, SUPER CHLOR and ADJUST
SET POINT questions – pressing the N/DOWN button in response to each question.
The LCD will then read "ADJUST ORP CONTROL TURN OFF? Y/N" (if the system is ON)
or ADJUST ORP CONTROL TURN ON? Y/N" (if the system is OFF). If you press Y/UP,
the system will turn on (or off depending on its current status). If you answer N/DOWN to
either question, the LCD will return to the home screen.
