actuator set point
When the temperature is below the minimum set point, the actuator is
closed. When the temperature rises to the minimum set point, the actuator
moves to the minimum position.
As the temperature rises, the actuator has four stages it moves through
until it reaches its maximum open position. This lets you gradually open
inlets instead of fully opening them when the temperature rises above a
single set point.
In other words, “when the temperature is here (stage set point), I want the
actuator to start opening. When the temperature reaches here (stage
differential), I want the actuator to be at this position (stage position)
percent.”
For more information, read Programming relays for actuator control on
page 49.

alarm biasing
Alarm biasing gives you the ability to add a "buffer" to the high alarm
temperature to help prevent the alarm from sounding on very hot days.
alarm condition
For the Ventilation module, there is an alarm condition when the low
alarm is enabled and the temperature is lower than the low set point, or
when the high alarm is enabled and the temperature is higher than the high
set point.
Other OMNI-Select modules have different alarms and alarm conditions.
For more information, read the user manual for the specific modules.
bias offset
Bias offset is the number of degrees to add to the high alarm temperature when
the outdoor temperature is higher than the alarm temperature.

comma separated
value (CSV)
CSV is a tabular data file consisting of fields stored as text and separated
by commas. You can import CSV files into programs such as databases
and spreadsheets.
curtain idle band
Curtain idle band is a temperature buffer around the curtain set point.
When the temperature is within the idle band, the curtains hold their
position. When the temperature is outside the band, the curtains cycle
open or closed.
Idle band is one of six curtain settings. For more information, read
Programming relays for curtain control on page 53.
