Operating instructions

DO NOT ENTER THE WATER.
Remove the spa cover and allow
water to cool. Once the heater
has cooled, reset by pushing any
button. If spa does not reset, shut
off the power to the spa and call
service or your local dealer.
DO NOT ENTER WATER.
Remove the spa cover and allow
water to cool. Once the spa
reaches 107˚F, (approximately
41.7˚C) the spa should automatically
reset. If spa does not reset call
service or your local dealer.
No Action required. The pumps
and the blower will automatically
activate regardless of spa status.
If the problem persists, contact
service or your local dealer (this
may appear temporarily in an
overheat situation and disappear
when the heater cools.)
If the problem persists, contact
service or your local dealer (this
may appear temporarily in an
overheat situation and disappear
when the heater cools.)
If problem persists, contact
service or local dealer.
Check the water level in spa. Add
water if necessary. If the water
level is okay, make sure the pumps
have been primed. If the problem
persists, contact your dealer or
service organization.
Follow actions required for HFL
message. Heating capacity of the
spa will not reset automatically;
you may press any button to reset.
Overheat - The spa has shut down.
One of the sensors has detected
118˚F approximately 47.8˚C at the
heater.
Overheat - The spa has shut down.
One of the sensors has detected
110˚F approximately 43.3˚C at the
heater.
Potential freeze condition exists.
Spa is shut down. The sensor that
is plugged into sensor “A” Jack is
not working.
Spa is shut down. The sensor that
is plugged into sensor “B” Jack is
not working.
Sensors are out of balance. If this
is alternating with the tempera-
ture, it my be a temporary condi-
tion. If the display shows only this
message (periodic blinking) the spa
is shut down.
A substantial difference between
the temperature sensors was
detected. This could indicate a
flow problem.
Persistent low flow problems.
(Displays on the fifth occurrence
of the “HFL” message within 24
hrs.) Heater is shut down, but
other spa functions continue
to run normally.

Filtration Cycles
Designate times when the pump activates on low speed to filter the spa water. The first filter cycle begins
1 minutes after the spa is energized. The second filter cycle begins 12 hours later. Filter Cycle duration is
programmable for 2, 3, 4, or 5 hours. The default filter duration is 2 hours. To change the filter duration,
press ‘Cool’ then ‘Pump 1’ and use the ‘Cool’ button to adjust. Press ‘Pump 1’ to exit programming.
Spa Modes
Spa Modes can be changed by pressing ‘Set Temperature’ then ‘Pump’.
Standar
d Mode constantly maintains the set temperature. The temperature displayed is current only when
the pump has been running for at least 2 minutes. The spa will run for at least 2 minutes every half hour to
determine if the spa requires heating. “St" will be displayed momentarily when you switch into Standard Mode.
E
conomy Mode heats the spa to the set-point when the spa is in a filtration cycle. In spas with continuous
circulation F1 & F2 Economy Cycle times must be set. However, when it is not in a filtration cycle it will heat
the spa to within 15° of the temperature set-point. The display will alternately flash “ECON” and the current
spa temperature.
Freeze Protection
Freeze Protection is activated if the temperature sensors in the heater detect a drop to 44°. All pumps
(including the blower) activate automatically and remain on until 4 minutes after the sensors detect that
the spa temperature has risen to 45° or higher. During this time “ICE” will be displayed and no button presses
will be recognized until the spa water has reached 45°.
Ozone
Ozone will only run with Pump 1 in low speed during filtration cycles. For hot tubs with filtration cycles, you
will want to increase filtration cycles to two, four-hour cycles. Hot tubs with continuous circulation pumps
do not need adjustment to their filtration cycles.
