USING THE MENUS
MENU TYPES
System Startup Settings - determines the type of system. For example,
the system is a hot water heating system with 0-10V modulating
motors. If the Startup Settings are not correct, the Harmony can not
operate the system correctly.
Set Point/Gain/Lead Stage Settings - These settings might need
occasional adjustment by operating personnel. These are the only
settings which may require changes after the Harmony has been
successfully initialized for your specific type of system.
Stage Settings - determine how the individual Stage outputs are
controlled. When installing the panel, each Stage must be set
correctly, or the Harmony either will not control the Stage or will
control them erratically.
System Settings - determine how the system will operate. These are
general settings which affect all Stages. The default settings will
generally work in most applications, but adjustments should be made
to fine-tune the performance of your system.
MENU BASICS
• The menus are in English and will guide you through the settings.
• To change a selection, rotate the black knob marked ADJUST and
PRESS TO SELECT (ADJUST/SELECT). Rotating the knob clock-
wise will move down the list of possible selections. Rotating the
knob counterclockwise will move up the list.
• A pointer in front of a menu line indicates that it is the one currently
selected.
• When the pointer is on the same line as the item to be selected, press
the black ADJUST/SELECT knob. This will either save the selection,
or bring up a new screen to make further changes to that menu item.
• The BACK button will return you to the previous screen without
saving any changes made.
CHANGING SETTINGS
• Some settings require a number, such as time or temperature to be
adjusted.
• These screens will be indicated with the title on top and then the
current numerical value for that setting.
• To change a selection, rotate the ADJUST/SELECT knob. Rotating
the knob will cause a pointer to appear. Both the old and new value
will be displayed.
• The BACK button will return you to the previous screen without
saving any changes made.
• When the new value (the one being pointed to) is correct, press the
ADJUST/SELECT knob. This will save the selection to memory and
return you to the previous menu.
