Voltage Meter:
Printed circuit board assembly that distributes voltage to selected compo-
nents.
Component that allows user to access functions provided by the circuit
board.
Device which measures electrical current conducted through a wire or elec-
trical device.
Chip on circuit board that stores hot tub software.
Switch that informs circuit board there is sufficient water movement to acti-
vate heater. This switch identifies the presence or absence of water flow.
Sensor that monitors water temperature inside the heater.
Device on circuit board that electronically connects (bridges) two points
together.
Device that measures the resistance in ohms (Ω) of a component or tem-
perature sensitive device (e.g. temperature sensor, heater element etc).
A device that produces ozone gas by passing air through a Corona discharge
(high voltage arc). All LED models introduce ozone 24 hours a day until a
JETS button is pressed or summer logic is activated.
Locations identified by numbers on circuit board.
Plug in connector containing the temperature sensor and hi-limit sensor
device connections.
Deactivates circulation pump and aftermarket ozone generator when hot
tub water reaches 2 °F (1 °C) above the set temperature. Hot tub water
must be 95 °F (35 °C) or higher for summer logic to activate.
Sensor that monitors hot tub water temperature.
Device that converts primary high voltage AC signal to a secondary low
voltage AC signal.
Device that measures AC or DC voltage potentials across components or
from a specific test point to ground.
