Glossary
Circuit board:
The main circuit board mounted behind the Outdoor Control Panel.
EMI (Electromagnetic interference) filter:
Protective circuit element that must be used between
the IntelliChlor transformer and supply lines.
Feature Circuits:
Programmable circuits that may control relays and/or valve actuators. For details,
see the EasyTouch PL4/PSL4 Control Systems Systems User’s Guide (P/N 522461)
High Voltage Compartment:
Large lower right compartment of Power Center for all high voltage
wiring including circuit breakers, relays, and GFCI.
High Voltage Panel/Compartment:
Removable panel for the high voltage compartment of
EasyTouch PL4/PSL4 Control Systems Power Center. The high voltage wiring including circuit
breakers, relays, GFCI and optional IntelliChlor transformer/filter.
Indoor Control Panel:
This EasyTouch PL4/PSL4 Control Systems remote controller with LCD
(liquid crystal display) is wired to the Personality board (EasyTouch PL4/PSL4) or Motherboard
(EasyTouch PL4/PSL4) in the Power Center. The control panel can be wall mounted inside a house
to control the EasyTouch PL4/PSL4 Control Systems.
IntelliChlor
®
(SCG):
Salt Chlorine Generator. Uses a process known as electrolysis to produce
sodium hypochlorite (liquid chlorine) from a low concentration of salt added to the pool water.
Model IC 20 Cell (P/N 520554) for pools up to 20,000 U.S. gallons (75 liters) and model IC 40 Cell
(P/N 520555) for pools up to 40,000 U.S. gallons (151 liters). The external IntelliChlor Salt Chlorine
Generator Power Center (P/N 520556).
iS4 Wireless Controller:
Four function spa-side remote. Spa wall or deck mounted.
Low Voltage Compartment:
Top compartment behind the main circuit board in the Power Center
for all low voltage wiring.
Low Voltage Raceway:
Vertical space in the left side of Power Center for low voltage cabling.
Mud Box:
Enclosure to provide mounting features for SpaCommand controller or iS10 spa-side
remote that is cast into gunite, concrete, or other spa wall/deck construction.
Outdoor Control Panel:
Control panel with flexible hinge installed in upper portion of Power Center
to control EasyTouch PL4/PSL4 Control Systems.
Power Center:
Enclosure without circuit breaker base. Used for distributing power for controlling
EasyTouch PL4/PSL4 Control Systems. Also known as the “sub-panel.”
Relay Circuits:
The circuits that control the relays on the EasyTouch PL4/PSL4 Control Systems
circuit board.
Screw Terminal Connector:
Removable connector that may attach to circuit board with multiple
sockets (anywhere from 2 to 12) to receive conductors from controllers and sensors; conductors
held by screw terminals; multiple conductors of a small enough gauge (usually 22 AWG) may be
coupled to a single socket of a terminal connector.
Salt Chlorine Generator (SCG):
Automated pool chlorinator that sanitizes using salt water (see
IntelliChlor Salt Chlorine Generator).
Transceiver:
Circuit board with attached antenna that can send and receive radio frequency
(wireless) transmissions. Used with QuickTouch
®
II Wireless Controller.
Wireless Controller (EasyTouch PL4/PSL4 Control Systems):
Wireless controller for the
EasyTouch PL4/PSL4 Control Systems with all the functionality of the Indoor Control Panel.
