SET THE DATE AND TIME
BEFORE USING THE SPA
Be sure to set the date and time before operating the spa (refer to page 10).
Vital control functions require the time and date to be set correctly.
WATER CHEMISTRY
MAINTENANCE
It is your responsibility to regularly check and maintain the chemical water
balance of the spa pool to ensure it remains within reasonable pH (acid/alkaline)
limits (7.4 - 7.6 pH). Unbalanced water chemistry greatly accelerates corrosion
and may lead to early product or component failure. Product or component
failures caused as a result of poor water chemistry maintenance will NOT be
covered by the SpaNET Product Warranty.

SV Series Features Overview
PowerSMART
Welcome to the eco-friendly world of power smart spa controls with the SV Series from
SpaNET. Sophisticated real-time current sensing and variable heater technology allows
the SV to make optimum use of any available power supply. Multi-phase capable the SV
Series also provides flexibility with connection to mains power supplies supporting
connection to 1,2 or 3 phases from 10 to 60A. Add in the host of exclusive PowerSMART
energy saving features such as the dedicated heat pump interface, Dynamic Thermal
Tuning, Off-Peak PowerSAVE software, and user-adjustable heating modes and the
SpaNET SV Series stands apart from all rivals as the most power efficient spa control
available that provides the lowest possible daily operating cost.
Variable Heater
Most SV Series controller models feature SpaNET’s innovative variable heater
technology. With real-time current sensing the variable heater will automatically alter its
power level (kW) to match the residual power available (amperage) after considering
any operating accessory loads (i.e. jet pumps, air blowers). The benefit is that you can
take advantage of a larger heater size for faster heat recovery and rest easy knowing this
same heater will automatically reduce its size to maximise heating input when accessory
loads are operating. The variable heater is automatically controlled and does not require
adjustment. SV Series spa controller models that include the variable heater can be
identified by a “–VH” suffix to the controller model number (i.e. SV3-VH).
Heat Pump Interface
The SV Series spa controls are the first in the world to feature a dedicated expansion
module for seamless integration of an energy efficient heat pump to the spa heating /
cooling contr0l system. The SV heat pump interface revolutionises spa temperature
control. We can now offer both automatic heating and cooling of the spa water (from
10°C -40°C) all conveniently controlled via the spa-side keypad, whilst also providing
greatly reduced heat recovery times which can be further reduced with the exclusive SV
element boost and fast heat up cycle options. The SpaNET SV heat pump technology
maintains your spa's water temperature using around 75% less energy than a
conventional electric heater resulting in an eco-friendly and amazingly cost efficient
appliance. If connected, the heat pump will automatically be controlled by the SV Series
spa controller. If the temperature is adjusted the control system automatically responds
and will use the heat pump to heat or cool where required to regulate the water to the
new set temperature point. With solid state diagnostics and real time heat pump
monitoring the SV series control system correctly looks after every need of the heat
pump ensuring long term reliability whilst delivering absolute minimum operating costs.
Dynamic Thermal Tuning
No two spas are the same when it comes to thermal performance and heat retention.
The SV control system will automatically adapt and tune itself to the thermal properties
of your spa pool in its environment, day to day, season to season, to reduce demand
heat cycling. Dynamic Thermal Tuning provides optimal thermal regulation whilst
minimising power usage, resulting in lower daily operating costs.
PowerSAVE (Off-peak filtration and heating)
Enjoy the benefits of greatly reduced off peak power tariffs to lower your spa’s daily
operating cost. The SV PowerSAVE technology controls automatic power consumption
to off peak times whilst maintaining spa water temperature and daily filtration times.
Simply enable PowerSAVE and set the tariff times and begin saving money.

Water Priming Mode
Purge air from plumbing system
TIPS ON FILLING SPA
•Before filling remove spa skirt and be sure that all valves in the plumbing
system are fully open to maximise the amount of air that can escape the pipe
work during filling
•Remove filter cartridge(s) before filling and be sure to fill the spa through the
filter itself to flood the pipe work with water and minimise the chance of air
pockets forming in the plumbing during the filling process.
•DO NOT fill spa by placing hose in the foot well. Filling a spa this way will create
a large number of air pockets in the pipe work and may cause difficulty when
priming. Always fill spa through the filter area.
•Once the spa is filled to the correct level attempt to power up the spa with the
filter cartridges still removed. Verify that the spa controller completes its
priming sequence and begins normal operation. Once normal operation has
been verified turn mains power off, re-install filter cartridge(s) and restart spa.
WARNING
RESTRICTION OF WATER FLOW DUE TO DIRTY FILTER CARTRIDGES IS THE MOST
COMMON CAUSE OF ER-3 FAULTS. IF THE SPA POOL HAS BEEN OPERATING
NORMALLY THEN INTERMITTENT ER-3 FAULTS START TO OCCUR THE FILTER
CARTRIDGE(S) WILL REQUIRE SERVICING.
DEPENDING ON TYPE OF FILTER CARTRIDGE(S) INSTALLED THE FILTERS WILL EITHER
REQUIRE CLEANING, SOAKING IN A FILTER CARTRIDGE DEGREASER SOLUTION OR
REPLACING. REFER TO SPA RESELLER / MANUFACTURER FOR DETAILS ON TYPE OF
CARTRIDGE INSTALLED AND RECOMMENDED CLEANING FREQUENCY & METHODS.
Every time the power is turned on the SV controller will initiate a water priming
sequence on start up. During a priming sequence the filtration pump will run for up to 20
seconds at a time in an attempt to purge air from the plumbing. The keypad display will
scroll PRIMING during this sequence.
If the spa controller is successful in clearing all of the air from the heater tube the system
will begin normal operation. However if air is still detected the spa controller will shut
down and latch on fault code (ER3-Water Prime).
How do I solve ER-3 WATER PRIME:
Press Pump A button to retry water priming sequence
Check spa is filled to correct operating level as advised by spa manufacturer
(refill if necessary)
Remove filter cartridge(s) and retry water prime
With mains power turned OFF, bleed airlock from pipe work by slightly
loosening couplings on front of filtration pump and allowing air to escape
With filter cartridge(s) removed use hose to flush water down pipe work in an
attempt to clear the air pockets from the plumbing
IMPORTANT NOTE
Do not allow the filtration pump to continue to run after five (5) x failed priming attempts.
Operating a pump without water for extended periods may cause damage to the pump.
Turns power off, wait ten (10) minutes and then try again later.
The in-heater water sensor constantly monitors the presence of water in the heater tube. If
at any time air bubbles are detected the spa controller will automatically cancel all current
operations and force a water priming sequence to begin. This will occur whether the spa is
in automatic mode or manual use. If the priming sequence is successful in clearing the air
pockets from the plumbing normal spa operation will resume in automatic mode. If
unsuccessful the spa controller will shut down and latch on fault code ER-3 Water Prime.

IMPORTANT NOTES
•A ten (10) second idle time out period exists on non-default display modes. If the display
mode is changed the screen will time out and return to the default display after ten seconds
of idle activity has elapsed (i.e. no button presses).
•At times the WTMP icon will not appear and the temperature reading may take a while to
update. This is normal and results from the SV control updating and performing dynamic
thermal tuning to your spa and its environment. If this occurs, the filtration pump may
need to run for up to ten (10) minutes before the WTMP readout is refreshed.
The SV keypads feature three different display modes to select from:

Adjusting Set Temperature Point
How to program the desired water temperature
Press and hold OR
Press to confirm & save
The SV series spa controllers have been designed with simplicity in mind. The intelligent software
constantly monitors the spa water, automatically controlling the heater and/or heat pump (if
fitted) to ensure the desired set water temperature is maintained and required level of daily
filtration achieved.
With set-and-forget technology, the spa user simply selects their desired water temperature
(Range: 10oC - 41oC; Default: 38oC) and thereafter the SV controller will automatically heat to and
maintain that selected water temperature. This is called demand heating - the filtration pump and
heater will be activated as required to maintain the set water temperature. The time spent heating
the spa and running the pump under normal operation will be taken into account and where
required the filtration pump will run for additional periods throughout the day to maintain the
minimum level of daily filtration.
Dependant on the amount of normal spa use, set water temperature, daily filtration times, and
climatic conditions being experienced, the SV controller will engage the heater and/or heat pump
(if fitted) for differing periods of time, at differing times of day. The advanced software constantly
monitors and recalculates after each heating / filtration cycle to ensure the correct daily filtration
time is achieved and desired set water temperature is maintained.
Unless adjusted the SV controller will automatically heat to and maintain the default temperature
of 38oC. The water temperature set point can be adjusted from 10oC to 41oC in steps of 0.2oC
increments.
Press and hold or to begin set temperature point adjustment
The keypad numbers will flash during temperature adjustment
Once desired set temperature point has been selected press to confirm
IMPORTANT NOTES
•During a heating cycle the SV controller may raise the water temperature up to 0.6oC above
set temperature point to provide an average water temperature of set point at most times.
•UUIf an optional heat pump is NOT fitted the spa controller has NO ability to cool the spa
water. Lowering the set temperature point will NOT cause the water to cool.
•If an optional heat pump IS fitted the spa water CAN be cooled as well as heated.
Lowering the set temperature point will ensure the heat pump engages/disengages a
cooling cycle (if required) to maintain the desired set water temperature.
•If the spa control has been in standby mode (idle) for some time and the set temperature
point is adjusted, the filtration/circulation pump may run for up to ten (10) minutes before
the heater / heat pump engages to heat or cool (heat pump only) the water.

Press to confirm & save
Press to enter adjustment
Press and hold +
\
IMPORTANT NOTES
•If Economy mode is selected and daily filtration time is set too low the spa water
may not have sufficient heating time to reach set temperature point.
•If Away mode is selected all heating is completely disabled. The heater will not
engage unless the water temperature falls below 4oC and freeze protection
activates.
•If a heat pump is fitted and demand cooling is required to maintain the set
water temperature, the demand cooling will also be governed by the heating
operating modes in the same way that demand heating is.
Heater Operating Mode
The SV controllers feature four different operating modes that effect demand heating
and filtration behaviour (refer table below).
Item Mode Notes
NORM Normal Normal operation for demand heating and filtration
ECON Economy Demand heating can only occur when filtration pump is running
AWAY Away Demand heating is DISABLED. Filtration is fixed at 1 hour
per day (the keypad will scroll “AWAY MODE” every 60 secs)
WEEK Week Monday to Thursday: Demand heating is DISABLED and filtration
fixed at 1 hour per day. Friday to Sunday: Normal Operation
Press and hold and buttons together until [MODE] is displayed
Press button to enter operating mode (MODE) adjustment
Press or to select desired operating mode
Press button to confirm and save setting
IMPORTANT NOTES
•The Week mode is ideal for spas used only on weekends or located at weekend
holiday homes. To minimize operating costs during the week (when the spa will
not be used) demand heating is disabled and filtration is reduced to 1 hour per day.
During Friday, Saturday and Sunday the spa controller will operate as if in normal
mode.
•If Week mode is selected, the spa controller will obey all programmed values (set
temperature, sleep timers, power save timers, filtration etc) on Friday, Saturday
and Sunday. Depending on current season and ambient temperatures the spa
water temperature may fall significantly during Monday to Thursday when
demand heating is disabled. The spa user must take into consideration all
programmed settings including sleep timers and power save timers for the spa to
have sufficient time to reheat to set temperature point on Friday (refer page20
Setup Menu for further details on programmable settings).

SV Series Spa Controls 13
Heating Control & Protection
Fast Heat Cycle / freeze and overheat protection
Fast Heat Cycle
After initial mains power on the SV controller will perform a fast heat up cycle that
enables continuous demand heating regardless of programmed sleep timers or choice of
Economy (ECON) or Normal (NORM) heating modes. Once the set temperature has
been reached the fast heat up cycle is cancelled and normal operation resumes.
The purpose of a fast heat up cycle is to help the spa reach set temperature as soon as
possible after it has been powered up. For new spas or spas refilled with cold water it is
desirable not to have sleep time or economy heating mode delay the time to takes for
the spa to reach set temperature point.
Note: AWAY mode disables a fast heat up cycle.
IMPORTANT NOTES
•A fast heat up cycle is cancelled by manually forcing the filtration pump to OFF via the keypad.
•For new spas or when a spa has just been refilled it is common for spa owners to test the
operation of each pump when the power is first turned on. This process will effectively
cancel the fast heat up cycle. After completing testing of spa functions remember to reset
mains power if you wish to reactivate the fast heat up cycle.
Freeze Protection
Freeze protection will be activated whenever the water temperature drops below 4oC. It
runs back to back 10 minute sanitise cycles and displays “WARM” on the LCD. It also
runs each spa accessory (ie. jet pumps and air blower) in sequence to run water through
the pipe work whilst running the filtration pump and heater. During the “WARM” cycle
the heater and heat pump (if fitted) will operate however heater load shedding may
occur when accessory pumps are running depending on controller settings.
At the end of each 10 minute “WARM” cycle the water temperature is checked. If it is
above 4oC freeze protection stops and the controller returns to its prior state. If the
temperature is not above 4oC another cycle will run.
Note: Freeze protection overrides sleep time or power save times – if the water
temperature drops below 4oC and the controller is in a sleep period it will wake up. So
even if high amounts of sleep time, power save time and a low set temperature point
have been programmed, the SV controller will always maintain the water temperature
at least above 4oC.
Defrost Cycle (Heat Pump models only)
During periods of low ambient temperatures defrost cycles may be required to prevent
the heat pump’s condenser from freezing. Ambient and condenser temperatures are
constantly monitored and defrost cycles will be automatically activated if certain
conditions are met. Defrost cycles run for a minimum of 3 minutes to a maximum of 10
minutes.
Overheat Protection
All SV controllers feature three forms of overheat protection:
•If sensed water temperature within the heater unit exceeds safe working limits
the heating element will be disabled and the controller will shut down and latch
fault code (ER4 - Thermal Trip). Normal operation will not resume until heater
element has cooled and mains power is reset
•If sensed water temperature exceeds 42oC filtration is stopped until the
temperature falls below 42oC to prevent heat rise from filtration pump
operation
•If sensed water temperature exceeds 45oC the controller will shut down and
latch fault code (Er5 - Pool too hot). Normal operation will not resume until
mains power is reset

SV Series Spa Controls 14
Pump Operation
Keypad pump button assignments
IMPORTANT NOTE
In some configurations if heater is ON, activating multiple pumps may cause the heater to load shed and turn OFF, or reduce
element power (variable heater models). This is to keep the system within its maximum current limit. The heater will be re-
engaged or returned to full capacity as soon as the number of pumps running is reduced.
Pump Buttons
The jet pumps and/or filtration pump are controlled
via the pump buttons on the keypad. The functions
of the pump buttons change depending on pump
configuration, however Pump-A button is mostly
used to control the filtration pump.
The intention is to make best possible use of these
buttons for all possible pump configurations. For
every press of a pump button the display will
temporarily show the selected pump state:
ON / OFF / LOW / HIGH / AUTO
and then revert to the default display mode. The
most common pump configurations and button
assignments are referenced in the table aside.
IMPORTANT NOTES
•In configurations where a pump button controls
the filtration pump and the heater is ON and pump
is to be turned OFF; the pump will turn OFF after a
5 second delay to allow the heater to cool down.
•If left running, pumps will turn off after a 30
minute time out period. Time out period can be
adjusted from 10 to 60 minutes via the Setup
Menu item T.OUT (refer page 21).
•If after manual spa use filtration pump is left OFF,
controller will revert to automatic mode 15
minutes after the expiry of the T.OUT period.

Sanitise Cycles
Automatic and manual water clean cycles
Press to activate sanitise cycle
Whilst the cycle is running the display alternates
between the W.CLN (water clean) title screen and
the minutes remaining in the cycle (refer above).
Sanitise Button
The sanitise button activates a twenty (20) minute sanitisation cycle that runs the
filtration pump and ozone / uv (if fitted) to filter the pool water to restore and refresh
water quality. With circ pump systems jet pump1 will also run for the full 20 minute
cycle. Where 2-speed filtration pumps are used the pump will run in high speed for the
duration of the cycle. In addition, at the start and end of the cycle, the controller will
sequentially (one at a time) run any additional pumps (pump2, pump3, pump4 if fitted)
and the blower for one minute each to purge the plumbing and clear any unfiltered
water trapped in those lines.
Press button to activate a 20 minute sanitise cycle
Press button again to cancel cycle (if desired)
IMPORTANT NOTES
•When the cycle is started automatic mode is enabled and if running any additional
jet pumps and the blower are turned off.
•If the controller falls within a designated sleep or power save period during a
sanitise cycle, the controller will not sleep until the sanitise cycle is finished.
Automatic Daily Sanitise Cycle
The controller will automatically run a 10 minute sanitise cycle every day at a user
adjustable time (Default = 9:00am). The automatic sanitise cycle works in the same
manner as a manual sanitise excepting that the cycle only runs for 10 minutes. This
feature cannot be disabled – only the time this cycle is activated may be changed via the
Setup Menu item W.CLN (refer pages 21 & 22).
IMPORTANT NOTES
•If the controller is in a sleep period at the specified automatic sanitise cycle time, it
will wait until the sleep period ends before the sanitise cycle runs.
•If the spa pool is in manual use (i.e. the loads have not timed out and the spa has
not returned to auto mode) at the time the automatic sanitise cycle is set to run
the cycle will be cancelled for that day.
