STRYKER CVAHU ZIO CONFIGURATION GUIDE
14
Abbreviations
AHU:
Air Handling Unit. The central fan system
includes the blower, heating equipment, cooling
equipment, ventilation air equipment, and other
related equipment.
CO:
Carbon Monoxide. Occasionally used as a
measure of indoor air quality.
CO
2
:
Carbon Dioxide. Often used as a measure of
indoor air quality.
CPU:
Central Processing Unit
cUL:
Underwriters Laboratories Canada
CVAHU:
Constant Volume Air Handling Unit; refers to
a type of air handler with a single-speed fan that
provides a constant amount of supply air to the space
it serves.
Echelon:
The Company that developed the LON®
bus and the Neuron® chips used to communicate on
the E-bus.
Economizer:
Mixed-air dampers that regulate the
quantity of outdoor air that enters the building. In cool
outdoor conditions, fresh air is used to supplement
the mechanical cooling equipment. Since this action
saves energy, the dampers are often referred to as
economizer dampers.
EMI:
Electromagnetic Interference. Electrical noise
that can cause problems with communications
signals.
EMS:
Energy Management System; refers to the
controllers and algorithms responsible for calculating
optimum operational parameters for maximum energy
savings in the building.
Enthalpy:
The energy content of air measured in
BTUs per pound (Kilojoules per Kilogram).
Firmware:
Software stored in a nonvolatile memory
medium such as an EPROM.
Floating Control:
Floating Control utilizes one digital
output to pulse the actuator open, and another digital
output to pulse it closed.
FTT:
Free Topology Transceiver.
IAQ:
Indoor Air Quality. It refers to the quality of the
air in the conditioned space, as it relates to occupant
health and comfort
.
I/O:
Input/Output; the physical sensors and actuators
connected to a controller.
I * R:
I times R or current times resistance; refers to
Ohm’s Law
:
V = I x R.
K:
Degrees Kelvin.
NV:
Network Variable; a Stryker CVAHU parameter
that can be viewed or modified over the Lon/S-bus
network.
PWM:
Pulse Width Modulated output; allows analog
modulating control of equipment using a digital output
on the controller.
RTD:
Resistance Temperature Detector; refers to a
type of temperature sensor whose resistance output
changes according to the temperature change of the
sensing element.
TPT:
Twisted Pair Transceiver.
VA:
Volt Amperes; a measure of electrical power
output or consumption as applied to an AC device.
Vac:
Voltage alternating current; AC voltage rather
than DC voltage.
VAV:
Variable Air Volume; refers to either a type of
air distribution system, or VAV Box Controller that
controls a single zone in a variable air volume delivery
system.
