minutes of operation unless done so manually. The Pump 1 indicator will illuminate while the pump is running in
High speed and flash while it is in Low speed. If the Filter Cycle indicator is illuminated , a filtration cycle has
begun and you will not be able to turn the pump off.
Pump 2 Key: Press this key once to turn Pump 2 onto Low speed, press this key a second time to turn
Pump 2 onto High speed, a third press will turn the pump off. A built-in timer will shut the pump off after 20

Temperature Set Key: Press the Up/Down Arrow key to increase the desired temperature, release
and press again to decrease the desired temperature. The temperature can be adjusted in 1BF increments from
59BF to 104BF (5BC to 40BC). The new setting will remain on the display for 5 seconds as a confirmation. During
this time the Temperature Program indicator will be illuminated to let you know this is the desired and not the
actual temperature. After 5 seconds the display will return to the current temperature reading. When the
temperature drops to 1BF below the set temperature, the heater will be turned on until the temperature is 1BF
above the set temperature. The Heater “On” indicator will illuminate while the heater is on and flash when there is
a call for heat and the heater has not yet been activated.

ERROR INDICATION
fLC
To assist the user in identifying problems with the spa, the system will display an
error message. These messages will be helpful when communicating with your local
dealer or qualified technician if a problem should arise.
PRESSURE or FLOW SWITCH ACTIVATED - This error will be
displayed only when the pump is not activated. Cycle the pump
through Low & High speeds then off. If the error does not clear
this is an indication that the pressure or flow switch is activated
with no water flow.
Contact your local spa dealer
fLo PRESSURE or FLOW SWITCH NOT ACTIVATED - This error will
be displayed while the is pump running. Cycle the pump through
Low & High speeds. If the error does not clear this is an indication
that the pressure or flow switch has not activated although there
is water flow.
Contact your local spa dealer
PTEMPERATURE SENSOR MALFUNCTION - This error will occur
when a problem with the temperature sensor exists. This error
may also occur if the system is activated while the water
temperature is below 35BF.
Contact your local spa dealer
OH
OVERHEAT or HIGH-LIMIT PROTECTION - There are three(3)
stages of over-temperture:
1 - The spa water has exceeded 112BF. The heater, pump and
accessory will be deactivated until the water cools to 109BF. Be
sure to check the actual water temperature with an accurate
thermometer.
2 - The spa water has exceeded 119BF. The heater will deactivate
while the pump and accessory will still operate. The blower (if
equipped) can be activated to help cool the water. WATER MUST
BE BELOW 119BF AND POWER MUST BE RESET TO CLEAR
THE “HL” ERROR
A dirty spa filter can also cause a restricted flow of water, be sure
the filter is cleaned regularly and ensure all water shutoff valves
are open.
If the system has been operating normally until now, the pump
may be overheating the spa. Refer to “Programing Filtration” on
page X and reduce the duration and/or number of cycles per day.
3 - If you’ve eliminated items 1 & 2 as problems, the high-limit
sensor may have malfunctioned.
