Main Settings Menu
The main settings menu can be accessed by pressing the
MENU button. To reduce the risk of untrained end users
altering the settings accidentally there are two 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 displayed with all functionality
available. The arrows shown at the bottom of the display
screen will invert colours and additional edit menus will be
displayed.
The following items can be viewed and/or edited
(dependent on access level).
• Domestic Hot Water (DHW)
• Heating/Cooling
• Schedule timer
• Holiday mode
• Initial settings
• Service (Password protected)
Use the F2 and F3 buttons to move between the icons.
The highlighted icon will appear as a larger version in the
centre of the screen. Press CONFIRM to select and edit
the highlighted mode.
