9-2. Setting the Main remote controller
After the power has been connected to the outdoor and hydrobox (See "7. FIELD WIRING"), the initial system settings can be entered via the main remote controller.
1. Check all breakers and other safety devices are correctly installed and turn on power to the system.
2. When the main remote controller is switched on for the first time, the screen automatically goes to Initial settings menu, Language setting screen and Date/Time
setting screen in order.
3. Main remote controller will automatically start up. Wait approximately 6 minutes whilst the control menus load.
4. When the controller is ready, a blank screen with a line running across the top will be displayed.
5. Press button E (Power) (refer to 9-1. Main remote controller) to turn on the system. Before turning on the system, perform initial settings as instructed below.
9-3. Main Settings Menu
The main settings menu can be accessed by pressing the MENU button. To re-
duce the risk of untrained end users altering the settings accidentally, there are
2 access levels to the main settings; and the service section menu is password
protected.
User Level – Short press
If the MENU button is pressed once for a short time, the main settings will be
displayed but without the edit function. This will enable the user to view current
settings but NOT change the parameters.
Installer Level – Long press
If the MENU button is pressed down for 3 seconds, the main settings will be dis-
played with all functionality available.
The colour of buttons is inverted as per right figure.
The following items can be viewed and/or edited (dependent on access level).
• Domestic Hot water (DHW)

• Schedule timer
• Holiday mode
