APOGEE Heat Pump Controller — Multi-Stage Owner's Manual
DO
Digital Output. Physical output point that generates a two-state signal (that is, ON/OFF,
OPEN/CLOSED, YES/NO, etc.).
English units
Foot-pound-second system of units for weights and measurements.
equipment controller
FLN device which provides additional point capacity to a field panel or provides individual
room or mechanical equipment control. The Heat Pump Controller — Multi-Stage is an
equipment controller.
field panel
Device containing a microprocessor for centralized control of system components and
equipment controllers. A field panel samples and processes field data, initiates control
actions, communicates with its operators, and generates reports, displays and warnings.
FLN
Field Level Network
intercept
Factor which converts analog values (used by the controller) to a form which the user can
understand (engineering units). Slope and intercept constants are determined by the type of
field input/output represented by the physical or virtual point.
FLN
Revised acronym for Floor Level Network. The term “Floor” is no longer used and has been
replaced with “Field”.
Ioopout
Output of the control loop expressed as a percentage.
OFF text
Text indicating the de-energized state of a digital point (for example, OFF, CLOSED, NO).
