Operation
Sensor offsets
All external transmitters shipped with Vapor-logic4 can be field
calibrated from the Setup menu. For example, if the system is
equipped with an RH transmitter, there is an RH offset setting.
The factory default for all transmitter offset settings is zero. The
sensors that have this adjustment capability are the humidity, duct
high limit, temperature compensation, and dew point transmitters.
Automatic drain sequence, tap/softened water
(See note at right for XT humidifiers.)
When configured to run a tap/softened water humidifier with
an automatic drain valve, Vapor-logic4 uses an automatic drain
sequence (ADS) to reduce mineral accumulation in the tank and
drain line, which decreases tank maintenance.
The automatic drain sequence starts by opening the drain valve to
empty the tank. When the drain duration ends, the fill and drain
valves remain open to flush the tank. When the flush duration
ends, the automatic drain sequence is complete and the humidifier
resumes normal operation. The default drain and flush durations
are model-specific and can be adjusted in the water management
section of the Setup menu.
Automatic draining and flushing parameters are defined in the
water management section of the Setup menu:

Defaults for this value are model-specific and are calculated
based on operating 200 hours at 100% capacity. Go to the Setup
menu to view or change this setting for your humidifier.

requirement is met, the automatic drain sequence can occur on
the first allowed day (allowed days default is all days).

be defined (default value is midnight).
For example, if you use factory default settings for the automatic
drain sequence, the first automatic drain sequence will occur at
midnight on any day of the week once the model-specific usage
requirement has been met. If you want to change these settings, go
to the water management section of the Setup menu.
Note that the automatic drain sequence is designed for a
tap/softened water humidifier with electric drain and fill valves.
Humidifiers using DI/RO water do not require automatic draining
and flushing, but this feature can be enabled if the humidifier has
electric drain and fill valves.
Drain algorithm for XT humidifiers
XT humidifiers employ a drain algorithm that
is written specifically for how electrode steam
humidifiers function. See “Electrode steam
humidifiers” on Page 57.
