CARNES HBGH Installation, Operation And Maintenance Manual page 20

Setpoint Timeout –
This page is where the Setpoint Timeout value is set. The
maximum amount of time allowed for the unit to reach setpoint
during a fill sequence is designated by the Setpoint Timeout. Its
default value is 30 minutes, but can be set as high as 255 min-
utes. After the timer expires during a fill sequence, the humidifier
assumes the drain valve is stuck open (due to sediment buildup),
and begins pulsing the drain valve to attempt to unclog it. After
the pulsing routine, the humidifier will attempt to reach setpoint for
a second and third time. After the third attempt without reaching
setpoint, the unit will shut down.
High Water Timeout –
This page is where the High Water Timeout value is set. This
is the maximum amount of time allowed for the unit to run in a
'Reduced Setpoint' mode (See Setpoints page). The timeout has
a range from 0 to 168 hours, with the default being 24 hours. If
the humidifier setpoint is artificially reduced due to a high water
situation, the humidifier will continue to run. If the humidifier
cannot work it's way back up the normal max/controlled setpoint,
the humidifier will shut down after the High Water Timeout value
elapses.
Boil Down Timer –
This page is where the Boil Down Timer is set. The Boil Down
Timer is variable between 0 and 255 seconds, with a default value
of 25 seconds. Setting the Boil Down Timer higher will result in an
increased water level, and less-conditioned water. This may be
helpful in reducing low water level induced arcing and corrosion of
cylinders. More water is consumed by the humidifier when the Boil
Down Timer value is increased.
Settings Password –
This page is where the password for the settings menu can be
changed or disabled.
If the password for the Settings menu is forgotten, it can be reset.
To do this, remove power to the humidifier, move the jumper on
W4 from pins '1 and 2' to '2 and 3', and power the unit back on.
Return the jumper to pins '1 and 2' afterward. Pins '1 and 2' are to
the left, and pins '2 and 3' are to the right.
The different yellow buttons on both setting pages allow for the
changing of different values. Below is a brief summary of each,
and more information can be accessed within the page itself.
