Chapter 3
3.1 Security
The security system is programmed to prevent access by unauthorized persons to control setup without User Password.
<PASSWORD INPUT>
<Password Input Screen>
When you press the [MENU] button, the password pop-up window will appear as shown in the figure above. You must
enter your user password “1234” to access the menu items screen.
• Set the password by using the Up/Down & Right/Left Key and press the Enter button.
• The password must consist of 4 numbers.
• The default User Password is 1234.
NOTE:
After entering the password, access to the setup screen will be granted until the LCD backlight timer times
out. The password will then need to be re-entered to access the setup screens. If you don’t give any controls on the
Setup Menu Screen, it will automatically return to the Main Screen. It is strongly recommended to change the password
after the initial access. If you set the system control to factory default setting, the password is initialized to the default
password “1234”.
NOTE: The password feature is disabled by default.

The lead pump must be set to a pump that is USED and not the Jockey pump.
If PUMP1 is set to JOCKEY, the Jockey pump will always start fi rst and cannot be the LEAD PUMP. The jockey pump
is not included in the lead lag sequencing. The jockey pump will operate alone unless the set pressure cannot be
maintained. Then the lead pump and subsequent pumps will start based on lead/lag sequencing. The jockey pump will
stop after the lead pump starts and a preset delay times out (JOCKEY STOP DELAY).
