HEAT LIGHT

The HEAT ON light illuminates when the heater is on.
The pump circulates on low-speed whenever the
thermostat calls for heat.

HEAT MODE

Your spa comes preset in the standard heat mode.
For most applications, the standard mode should be
used. If you are in a warm weather climate and the
spa does not require as much heat, the economy
mode may work best. For a vacation home or for
very infrequent use, the sleep mode provides filtra-
tion and circulation with lower energy demand. In
economy mode your spa heats only during the filter
cycle. In sleep mode your spa will maintain a water
temperature that is 20°F (7°C) below the set tem-
perature. This ensures your spa will be ready to use
more quickly (allow about one hour per one degree F
for heating your spa's water) when increasing the
temperature to the desired level.
The spa's heat mode can be adjusted to one of
three different settings:
Standard Mode
The spa water heats to the temperature as set at the
bather's panel. In this mode the filtration pump turns
on for two minutes every half-hour to "poll" or check
the water. If heat is needed the unit heats to the set
temperature. The LCD window steadily displays the
actual temperature in this mode.
Economy Mode
In this mode the spa only heats to the set tempera-
ture during a filter cycle. The LCD window displays
"Ecn" alternately flashing with the actual temperature
when the spa is up to temperature and "Ecn" steadily
when the spa's water temperature is below the set
temperature.
Sleep Mode
Your spa will maintain a water temperature that is 20°F
(7°C) below the set temperature. Heater functions
only during a filter cycle. The LCD window displays
"SLP" flashing alternately with the actual temperature
when the spa is up to set temperature and displays
"SLP" steadily when below set temperature.
