Idle Screen
The Idle screen provides a convenient way to monitor the
humidifier’s basic operation. Depending on system options, the
system set point, the actual space condition, and/or the system
demand predominantly appear on the Idle screen.
The top line of the display shows the current mode of the
humidifier: Auto, Test, Standby, or Manual Drain. For Vapor-logic
3
versions 5.x.x (systems with multi-tank configuration capability),
the top line also shows tank identification.
The second line is a system status line. This line continuously scrolls
through current system status items. Depending on your system’s
options, this can include Filling, Skimming, No Duct Air Flow,
or High Limit Disable. See Page 57 for a complete list. The soft
keys provide quick, direct access to the Control Modes screen, the
Alarms screen, or back to the Main menu screen.
When the system is configured for potable or standard water, a
tank-level indicator appears in the upper right corner of the screen.
On potable or softened water systems, a three-probe system detects
more information on the water level control system, see Page 8.
When water is in contact with all three sensing probes, the full tank
graphic appears. When water is in contact with the bottom two
probes, the mid level tank graphic appears. When water is only in
contact with the bottom probe, the low level tank graphic appears.
When there is no water in contact with any probes, the empty tank
graphic appears.
