menu 3), the Group #1 static pressure set point will be displayed (“Press Spt=” item under menu 5).
If SWITCH is pressed again, the actual pressure will be displayed again. Note that the SWITCH key
will not work with every menu item. Table 4. Status and Table 4 list the SWITCH key destinations for
all applicable menu items. The SWITCH key has two additional functions: (1) it can be used to return
the display to the menu and item it was at prior to an alarm (see “ALARMS Key” above) and (2) it
can be used in conjunction with the Menu NEXT or PREV key to change the controller the RMC
Panel’s keypad/display is interfaced with (see “Changing the Keypad-Controller Interface” below).
Menu Group
The keys in the Menu group allow you to choose the menu you want to display. Refer to Figure 2.
Prev Key: When the Menu PREV key is pressed, the display will scroll to the previous menu in the
structure. This action will occur regardless of the current menu number. Note that you can “wrap
around” from the first menu to the last menu by pressing the Menu PREV key twice.
Next Key: When the Menu NEXT key is pressed, the display will scroll to the next menu in the
structure. This action will occur regardless of the current menu number. Note that you can “wrap
around” from the last menu to the first menu by pressing the Menu NEXT key twice.
Item Group
After you select a menu, you can choose the item you want to display by using the keys in the Item
group. Refer to Figure 2.
Prev Key: When the Item PREV key is pressed, the display will scroll to the previous item in the
current menu. Note that you can “wrap around” from the first item to the last item by pressing the
Item PREV key twice.
Next Key: When the Item NEXT key is pressed, the display will scroll to the next item in the
current menu. Note that you can “wrap around” from the last item to the first item by pressing the
Item NEXT key twice.
Action Group
The Action group keys allow you to clear alarms or change set points and parameters in the selected
item’s field(s). Note that the password must be entered before any set point, parameter, or schedule
changes can be made. See “Password Protection” above for more information.
Incr Key: When the INCR key is pressed, the entry in the item’s selected field will change to the
next higher value or next available selection. The field being edited will flash until the ENTER or
CLEAR key is pressed.
Decr Key: When the DECR key is pressed, the entry in the item’s selected field will change to the
next lower value or previous available selection. The field being edited will flash until the ENTER or
CLEAR key is pressed.
Enter Key: When the ENTER key is pressed, the entry in the item’s selected field will be locked in.
If the selected item has one field, pressing ENTER also completes the edit. If the selected item has
more than one field, pressing ENTER also makes the next field available for editing with the INCR
and DECR keys. If no change is desired, press ENTER until the desired field is flashing or the edit is
complete. (It is possible to initiate an edit of a multi-field item by pressing the ENTER key. In this
instance, the first field would be left unchanged and the second field would be available for editing.)
Clear Key: The CLEAR key is used to clear alarms and edited (flashing) fields. When a specific unit
controller alarm is in the display, pressing CLEAR will clear the current alarm. (At the RMC Panel’s
keypad/display, you must change the keypad-controller interface to the unit with the alarm to do
this. See below.) When an item field is being edited, pressing CLEAR will restore the field’s previous
entry and end the edit.
