Appendix A: Glossary
actuator An actuator is a device that has a mechanical arm that extends and retracts.
Actuators control elements that are not OFF or ON. Instead, they vary by a
percentage. For example, inlets can be open various distances from 0 to 100
percent.
Typically, linear actuators connect directly to the inlets, or connect using cables
and pulleys. Inlets are usually located in ceilings or walls. Inlet systems are often
spring loaded to help close the inlets, or counter weighted to help open the inlets.

Connecting actuators
on page 24.
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.”

alarm bias High temperature biasing helps prevent alarm conditions on days when the
outdoor temperature is above the
high temperature alarm
set point.
For more information, read
Programming alarm settings
on page 90.
alarm silencing Alarm silencing temporarily disables an alarm setting after an alarm has been
acknowledged. This prevents the alarm relay from activating immediately after
acknowledging the alarm if the condition is still present.

Programming alarm settings
on page 90.
control
elements
Control elements are devices connected to the Supra, such as fans, heaters,
actuators, and so on.
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
