DISPLAYS AND INTERNAL CONTROLS
FRONT PANEL DISPLAYS & CONTROLS
The display on the front panel of the humidifier cabinet con-
tains the “On-Off-Drain” switch, the LCD True Touchscreen
display and the “Fill”, “Drain”, and “High Water” LED.
“ON-OFF-DRAIN” SWITCH
In the “On” position the humidifier will operate if all
controls are calling for humidity. The “Off” position is used for
seasonal shut down if desired. The “Drain” position is used
to drain water from the steam cylinder for maintenance.
The fill solenoid valve will be on whenever the drain is
activated to reduce the drain water temperature.
LCD TRUE TOUCHSCREEN DISPLAY
This LCD True Touchscreen display offers a user
friendly interface to control and monitor many aspects
of the humidifier. The screen uses pressure sensitive
technology. Depressing on the labeled buttons on the
designated area of the screen will allow you to navigate
through the different menu pages.
“HOME SCREEN” PAGE
The “Home Screen” page is the main screen through which
most other pages can be accessed. The “Home Screen”
displays the current steam output in Lb./Hr. (or Kg/Hr.,
selected in “Settings”). The main “Home Screen” features
four navigation buttons, Carnes Logo (providing contact
info to the factory and the company website), Steam Menu,
Menu, and Settings. The “Home Screen” will display a
“Service Required” indicator when a current service issue
is indicated. The “Service Required” and Steam Output
number will illuminate red. Tap on “Service Required” to
access the service required page which indicates what
service issue is being detected.
Figure P
When CarnesLink is being used, the “Back End Override”
indicator is displayed only when the connected building
management system requests the unit to be set to “off”
or “drain” while the unit is “on”. When selected more
information is provided about the override.
“SERVICE REQUIRED” PAGE
The “Service Required” page outlines any service issues that
are in need of being resolved. Many issues can be traced back to
variability in water parameters, and often the solution can
be dealt with through the changing of cylinders or modifying
timer values within the “Settings” page. This page is used
to alert the user and direct them on the right path towards
resolution.
“FILL” LED
The FILL LED is a blue light illuminated when the Fill Valve is
activated. An activated Fill Valve allows water to flow into the
cylinder of the humidifier. An analogous indicator, and a
description of its operation, is offered in the “Menu” screen
under “Component Activity”.
