Operation
The system has a scrolling display which displays the current Discharge
Temperature, as well as Relative Humidity and Airflow CFM (if equipped
with airflow monitoring and control). The menu is separated into sub-menus
for ease of use, and only the options the unit is equipped with will be
displayed. When navigating the menu blinking items are set points that can
be changed, while non-blinking items are statuses which can only be
viewed.
To turn the unit on or off, press the “up arrow” to access the Fan
Command. Use the “up arrow” to select the desired option, then press the
center button “menu” to return to the main display.
To change set points such as discharge temperature or discharge humidity,
press the “menu” button until you see “SET POINTS” in the top right of the
screen. Press the “up arrow” to enter this sub-menu. Your first choice will
be “TEMP_SET_POINT”. Use the up arrow to select the desired discharge
temperature. When you have made your choice, press the “menu” button to
move to the next menu item, which will be the Discharge Humidity Set
Point. Again, use the “up/down” arrow buttons to make your entry and
press “menu” when finished. Continue scrolling through the Set Points sub-
menu until all of your desired settings are completed. When scrolling the
menu and you see the option “BACK” in the top right, pressing the “up
arrow” will take you to the previous menu.
Scrolling through the “STATUS” sub-menu will allow you to view the status
of all of the unit sensors, cooling, humidity and burner operation. This is
useful for checking unit operation or outdoor conditions.
The “ALARMS” menu will only be displayed if there is a system alarm, as
indicated by the blinking alarm bell on the display. When an alarm is
present, scrolling through this sub-menu will allow you to view the alarm(s)
in “plain English” enumerated text. This is useful for diagnosing the unit in
the event of a problem.
The “CONFIG” menu is where the primary operating set points for the unit
are set such as the minimum and maximum allowable discharge
temperatures, as well as other items. Again, use the “menu” button to scroll
through the sub-menu and the “up/down” buttons to edit your selection.
