5/CONNECTING TO AN EXTERNAL
TIMER (HOME AUTOMATION)
If you use a centralised control system (or an external controller) to control your pool, your
Ei chlorinator must be set to allow communications between the two appliances.
Example of a timer:
5.1 SETTING THE TYPE OF EXTERNAL TIMER
IMPORTANT NOTE: The timer type must be set before connecting the control cables
to the external control box.
Process:
1. Switch on the Ei appliance.
2. Wait for the completion of the boot sequence (a few seconds) but leave it 'OFF'.
3. Press and maintain the key. After approximately 5 seconds the current external
timer model will be displayed.
4. Maintain the key pressed until the desired model is displayed.
5. Release the key. The Ei appliance will return to the default LCD screen.
WARNING: users of Jandy 'REV L' or more recent versions
It is essential that the external controller setting be set to JANDY L/M if a Jandy Aqualink
'Rev L' controller or a more recent version is to be connected. If the wrong setting is
selected the Jandy Aqualink control unit may be damaged.
5.2 PRECAUTIONS WHEN WIRING AN EXTERNAL CONTROLLER
IMPORTANT: The wiring of the controller should be performed by an experienced
pool specialist.
Before connecting or disconnecting any wires make sure the power supply to both the external
timer and the Zodiac Ei unit has been cut off.
