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
electrical 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 water flow.
Sensor that monitors water temperature inside heater.
Device on circuit board that mechanically 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 dis-
charge (high voltage arc) chamber. Introduce ozone 24 hours a day until a
JETS button is pressed. Both filter cycle and ozone production is canceled
after a JETS button is pressed and then turn back on approximately 5 min-
utes after jets turn off.
Locations identified by numbers on circuit board.
Plug in connector containing the temperature sensor and hi-limit sensor
device connections.
Deactivates Circulation Pump, CLEARRAY and/or optional ozone genera-
tor 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.
