Glossary - Lennox iComfort S30 Installation And Setup Manual

AC - air conditioner
AHC - Air Handler Control
CEHB - Cold end header box
CFA - Comfort fault alarm
CFM - Short for cubic feet per minute, a measurement of the velocity at which air
flows into or out of a space.
DAS - Discharge air sensor
DAT - Discharge air temperature
DC - Direct current
DCM - Damper control module
Deadband - Is an interval of a signal domain or band where no action occurs (the
system is dead).
Dual-Fuel - Refers to a system having the option of two fuel sources to maximize
efficiency. Dual-fuel systems optimize energy use by selecting the best source of
fuel, like Lennox systems that combine an electric heat pump with a high-efficiency
gas or oil furnace.
EIM - Equipment Interface module
HEPA - is an acronym for "High Efficiency Particulate Air" or "High Efficiency
Particulate Arrestance." This acronym refers to a filter that is manufactured, tested,
certified, and labeled in accordance with current HEPA filter standards.
HP - Heat pump
IFC - Integrated Furnace Control
A
LED - light-emitting diode (LED) is a two-lead semiconductor light source. It
is a pn-junction diode, which emits light when activated. When a suitable voltage
is applied to the leads, electrons are able to recombine with electron holes within
the device, releasing energy in the form of photons.
LVCS - Lennox Ventilation Control System
Mag-Mount - A wall base that has inter-connects between the wall display and the
Smart Hub.
MAX - Maximum
Modulating - The process of varying one or more properties of a high-frequency
periodic waveform.

GLOSSARY

OAS - Outdoor air sensor
PCB - Printed circuit board
PFC - In electrical engineering, the power factor of an AC electrical power system
is defined as the ratio of the real power flowing to the load, to the apparent power
in the circuit,[1][2] and is a dimensionless number in the closed interval of -1 to 1.
PureAir - A system uses exclusive UVA-light technology to attack all three classes
of indoor air contaminants–particles, mold/mildew/bacteria and odors/chemical
vapors. It not only reduces, but also destroys ozone, a known lung irritant.
RPM - Number of times the shaft of a motor, rotates in one minute. RPM is a
function of the design of the equipment and the power supply.
RSBus - Residential Serial Bus * the means for transmitting data within the
communicating system.
Set point - It is the temperature the control system aims to maintain.
Smart Hub - System and network controller
SSA - Single set point
SSID - Is a case sensitive, 32 alphanumeric character unique identifier attached
to the header of packets sent over a wireless local-area network (WLAN) that acts
as a password when a mobile device tries to connect to the basic service set (BSS)
-- a component of the IEEE 802.11 WLAN architecture.
TEMP - Temperature
TXV - The thermostatic expansion valve (TXV) is a precision device, which is
designed to regulate the rate at which liquid refrigerant flows into the evaporator.
VAC - Variable alternate current
VDC - Variable direct current
UV - Ultra-violet
UVC - Refers to ultraviolet light with wavelengths between 200 – 280 nanometers
(nm). Light in the UVC wavelength can be used for disinfecting water, sterilizing
surfaces, destroying harmful micro-organisms in food products and in air.
Wi-Fi - A facility allowing computers, smartphones, or other devices to connect to
the Internet or communicate with one another wirelessly within a particular area.
