CARNES HBGH Installation, Operation And Maintenance Manual page 21

Calibration Password –
This page is where the Humidifier Unit Code, the four digit number
identifying the humidifier, is programmed into the unit. This page
is password protected, and number should not be modified by the
end user. Contact the factory if further information is needed.
Corrective Drain Length –
This page is where the Corrective Drain Length is set. This value
represents how much water should be drained from the cylinder
when the humidifier senses a corrective drain is needed. As
water boils from the humidifier, minerals increase in the cylinder
causing the water to get more conductive. Increasing the length
of the drain flushes more conductive material from the humidifier,
decreasing the water conductivity.
The input here is a percentage value. To set the Corrective Drain
Length to drain 20% of the cylinder during a corrective drain, input
020. To drain all of the tank, input 100. 30 is the default value, and
only multiples of 10 between 20 and 100 can be entered.
"HELP"
The help pages consist of maize color buttons labeled with
questions. When a button is pressed, information will be given
answering and/or giving information about the subject in question.
A basic help page consists of text and/or diagrams to help the user
through basic problems.
For example, in the picture above the question of how to install a
high limit humidistat is answered with a diagram and correspond-
ing text. Some pages consist of more buttons to help guide a
user through different processes. These buttons can be used and
referenced as needed.
Checkboxes –
There are a few operational options that do not need separate
pages, and therefore are only enabled/disabled via checkboxes on
the main Settings Page. Their functionality is described as follows:
The Drain Valve Pulse option is enabled by default. This option
allows the drain valve to pulse when the humidifier executes a
corrective drain. This actuates the water within the drain pip-
ing, allowing for minerals buildup to be discharged more eas-
ily. Enabling this option will make the unit noisier whenever a
corrective drain is executed.
The 72-Hour Drain is disabled by default. This option, when
enabled, allows the humidifier to drain the cylinder completely after
72 hours of idle operation.
The LCD Auto-Dim is disabled by default. This option, when
enabled, will automatically turn off the backlight of the LCD after 15
minutes of idleness. This feature can save on energy consumed.
The Kg./Hr Readout is disabled by default. This option, when
enabled, will turn the steam readout on home page, and in the
upper right hand corner of other pages, into Kg/Hr instead of Lb/
Hr.
