802.11: Refers to a family of specifications developed by the IEEE for Wireless
LAN technology. 802.11 specifies an over-the-air interface between a wireless
client and a base station or between two wireless clients and provides 1 or 2 Mbps
transmission in the 2.4 GHz band using either frequency hopping spread spectrum
(FHSS) or direct sequence spread spectrum (DSSS).
802.11b: An extension to 802.11 that applies to Wireless LANs (WLAN) and
provides 11 Mbps transmission (with a fallback to 5.5, 2 and 1 Mbps) in the 2.4 GHz
band. 802.11b uses only DSSS. Throughput data rate is 5+ Mbps in the 2.4 GHz
band.
802.11g: An extension to 802.11 that applies to Wireless LANs (WLAN) and
provides 54 Mbps transmission (with a fallback to 1, 2, 5.5, 6, 9, 11, 12, 24, 36,
and 48 Mbps) in the 2.4 GHz band. 802.11g uses Orthogonal Frequency Division
Multiplexing (OFDM). Throughput data rate is 11+ Mbps in the 2.4 GHz band.
Access Point: An Access Point (AP) is stand-alone wireless hub that allows any
computer that has a wireless network adapter to communicate with another
computer and to connect to the Internet.
Client computer: The computer that gets its Internet connection by sharing either
the host computer’s connection or the Access Point’s connection.
Expansion Kit: A kit that includes additional auxiliaries to an existing Personality
Kit. Requires a Load Center for each Expansion Kit.
Feature Circuits: Programmable circuits that can control non-high voltage
circuits, and valve actuators.
Freeze Protection: A circuit with freeze protection circulates water to protect
pipes from freezing, if the outdoor air temperature sensor detects the temperature
is getting close to freezing (below 36° F).
Gigahertz (GHz): A unit of frequency equal to 1,000,000,000 cycles per second.
High Voltage Compartment: Large lower right compartment of Load Center for all
high voltage wiring including circuit breakers, relays, and GFCI.
Host computer: The computer that is directly connected to the Internet using a
modem or network adapter.
Indoor Control Panel: The IntelliCenter™ Control System color touch LCD screen
is wired to the Personality board in the Power/Load Center. The control panel can
be wall mounted inside a house.
iS4: Four function Spa-Side remote. Can be spa wall or deck mounted.
iS10/SpaCommand: Up to ten function spa-side remote with temperature
changing capability. Can be spa wall or deck mounted.
