THERMOSTAT
The thermostat is a highly precise temperature control. The spa’s thermostat is designed
to provide you with optimum control of the spa water temperature. The maximum setting
is approximately 104
°
F (40
°
C) 2% accuracy. As the knob is turned counterclockwise,
the temperature will drop in ever increasing proportions. This geometric temperature
scale allows you much greater precision and control at the upper temperature. We
suggest that once you find the temperature you like best, identify its location on the
control.
JETS
When the jet switch is activated, the pump is switched to high-speed operation. You will
notice that, occasionally, when the pump is on high-speed and you press the “jets” button
to turn it off, it continues to operate on low speed. This may be because the thermostat is
calling for heat or the time clock is in a filtration cycle.
BOOSTER PUMP (Optional)
When the booster switch is activated, the booster pump is switched to High-speed
operation. The second pump (booster) is a single-speed pump.
AIR
When the air switch is activated, the air blower will turn on/off.
IMPORTANT: In both 30 Amp/220V and 20 Amp/110V systems, activating the jet (high
speed pump) or the air blower will automatically de-activate the heater. In 50 Amp/220V
systems, heating can take place during operation provided that the thermostat is set high
enough to demand heat.
LIGHT
When the light switch is activated, the 12V-spa light will turn on/off. There are two color
lenses included with your spa, which may be placed over the light lens.
