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’s.
“ON-OFF-DRAIN” SWITCH
In the “On” position the humidifier will operate if all con-
trols 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 the neces-
sary interface to control and monitor many aspects of the
humidifier. On the home screen is the current steam output
in Lbs./Hr. (or Kg/Hr). To select either is available in the
settings menu. A “Service Required” indicator and button
outlining current service issues, indicators for the four basic
controls necessary for operation (control humidistat, high
limit humidistat, air flow switch and door interlock), and
various buttons which navigate to other menu pages when
pressed are also available on the home page screen. The
menu pages and their capabilities are detailed further in
“True Touchscreen Menu Pages” section of this document.
“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 “Component
Activity” menu.

“DRAIN” LED
The DRAIN LED is a red light illuminated when the Drain
Valve is activated. An activated Drain Valve allows water
to drain from the humidifier. An analogous indicator, and
a description of its operation, is offered in the “Component
Activity” menu.
“HIGH WATER” LED
The HIGH WATER LED is an orange light illuminated
when the High Water Sensor is activated. An activated
High Water Sensor indicates that the water has risen to the
maximum allowable level in the cylinder. This can be a
normal situation, particularly if the cylinder is being filled
with mostly unconditioned water. An activated High Water
Sensor can also be a sign that the cylinder is close to
end-of-life and needs replacing, or, in rarer cases, the
cylinder is not conductive enough for the fresh water
entering the humidifier. An analogous indicator, and a
description of its operation, is offered in the “Component
Activity” menu. More information on troubleshooting High
Water situations can also be found through the “Help” menu
on the home screen.
HUMIDIFIER TRUE TOUCHSCREEN MENU PAGES
The humidifier True Touchscreen user interface uses color
conventions to help the user navigate the controls. The colors of
different buttons indicate the following.
1. Gray —
Dim LCD is the only gray button. More information is available
in the “home” page description.
2. Orange —
Orange buttons represent the object or subject described
across the button. Most orange buttons have an indicator
next to them, which can change in color, e.g. green, yellow or
gray. Pressing orange buttons will bring you to a page which
describes the object or subject in question.
3. Yellow —
Yellow buttons navigate a user to a new page dedicated to
a set of functions. For example, the “Humidistat Demand”
button brings the user to a page that shows what percentage
demands both the Control and High Limit Humidistats are
currently requesting, and details their functions. The bottom of
each page, other than the home screen, has a square “Back”
or “Home” button dedicated to directing the user back to their
previous page.
4. White —
White buttons are used for confirming or entering data into the
touchscreen. For example, they are used to confirm a change
to the “Max Output” parameter, or entering a password to
access the “Settings” menu.
