INSTALLATION INSTRUCTIONS
Controller Mounting
Find a suitable location to mount the control box. Ideally as with all pool equipment it should
be installed out of direct weather and no closer than 3 meters from the waters edge. Lift up
the two mounting tabs and use two appropriate screws to mount the control box to the wall,
keeping in mind that the power cable is 1. m long and should be plugged directly into a
general power outlet, not into an extension lead.
Pressure Switch or Flow Switch for Retro-Fit (Booste ) Systems - Optional
If the V2 Controller is to be fitted to a Retro-Fit (Boosted) System the mains power cable is
to be plugged into its own power point. A Pressure Switch should be fitted between the main
Filter Pump and Filter or a Flow Switch straight after the filter. All must be in a vertical
position and plugged into the left hand plug socket beneath the controller. This will ensure
that the booster pump only activates if the main pool pump is operating. When a Pressure or
Flow Switch is to be used the controller must have this function turned on. To do this ensure
the power is turned off, remove the lid and move the black jumper link marked J1 to
connect pins 5 + 6. Refit lid and switch power back on, a 33 will briefly be displayed during
start up. To switch off the pressure switch mode simply reverse the process.
Pool Sensor
For stand alone systems with separate suction and return the pool sensor must be fitted into
the suction line of the solar boost pump, preferably in a position out of direct sunlight. For
retro-fit systems the pool sensor must be fitted in the suction line of the main filter pump or
between the outlet of the filter and before the take off Tee fitting for the solar boost pump.
It is recommended that a 14.5mm hole be drilled in the PVC pipe, this can be carried out
using a Dontek PD01 grinding drill or a small pilot hole can be drilled and a 14.0mm drill-bit
used spinning in a counter clockwise direction to minimize the chance of shattering pipe.
Insert the grommet into the pipe and gently push in the black sensor barb. The green sensor
plug is to be fitted to the centre plug socket.
Roof Sensor
Roof sensors must be fitted into a small piece of solar collector or equivalent and attached to
the roof. The best location is within arms length of the gutters edge of the house or shed as
long as the sensor end is not shaded and is on a roof of similar aspect of the main collector.
It must not be fitted on top of the solar collector or fitted to high points on the roof like
Ridge Capping as false readings will be detected.
Keep in mind that it is of the utmost importance to keep the roof sensor as short as possible
as this will assist in the longevity of the sensor and controller in the event of electrical storm
activity and power surges. Sensor cables must not be run parallel to power cables and
run lengths should be less than 50m. Cable ties should be used to fasten the sensor cable to
the cold water inlet pipe making sure that the ties are approximately 10mm from PVC
fittings. Cable ties should be tightened only firm, over tightening can cause breaks in the
outer PVC if not careful. If the cable is to be run under ground a conduit must be used to
protect the wire and there is to be no cable joins within, conduit ends must be sealed to
prevent water ingress. Any excess cable shoul be remove an re-fitte ensuring
that the wire en s are tinne with sol er. The sensor plug is to be fitted to the right
hand socket.
Notes:
All excess cable must be removed; coils of cable are not permitted under any circumstances and must not
be tied to 240V wiring. If the cable is to be extended with non genuine cable a size of 14/020 should be
used. Any cable joins must be sol ere an this inclu es where the cable enters the terminal
block at the case base. Heat shrink is to be used over soldered joints to eliminate moisture ingress. If the
cable end is to be refitted to the plug sockets then the polarity must be observed as incorrect polarity will
show an error as stated in Fault Diagnosis. The sensor cable with the thin white trace is the positive and
should be fitted to the right hand cable entry when the screws are in a vertical position.
Once cables have been correctly fitted the unit can be turned on.
Clock:
This model is fitted with a settable 24 hour clock, if the clock needs to be adjusted then hold the up and
down temperature buttons together until the display goes blank, then release the buttons.
While the minutes light (M) is flashing rapidly, use the up or down buttons to set the minutes then press the
select button. The (H) light will now be flashing rapidly so using the up or down buttons set the hours then
press select.
The V2 will now resume in summer mode (auto).
NOTE: it is a 24 hour clock so 3 pm is 15 (add 12 after midday).
Setting the clock correctly ensures the booster pump will run only when maximum heating is
available, that is from 0800h (8 am) till 1800h (6 pm). It also ensures that the booster pump will not
run at night to sample the pool water. Night time is indicated by a flashing AUTO light.
Fault Diagnosis
In the event of a cable or sensor failure, the display will indicate the type of failure as follows;
ROOF SENSOR.
A display of 99 indicates a broken or disconnected sensor cable or open circuit sensor.
A display of indicates wrong polarity connection or short-circuited cable or sensor.
A display of 9 indicates a high sensor reading out of normal operating range.
A display of 00/03 indicates an over extended or coiled sensor cable.
POOL SENSOR
A display of 77 indicates a broken or disconnected sensor cable.
A display of 66 indicates wrong polarity or short-circuited sensor cable.
A display of 67 indicates a sensor reading out of normal operating range.

MODEL V2TC Digital Solar Controller
OPERATING INSTRUCTIONS
Summer Mo e (AUTO) is normal operating mode used during the Pool Swimming Season. You may
set the desired pool limit by pressing the UP or Down Buttons. The display shows the pool temperature
then flashes the limit setting and light, the pump light and pump will be on when solar gain is available.
Manual Mo e (PUMP/MAN) is used to prime, clean or test the pump. To select manual mode press
the SELECT button until the PUMP/MAN light is illuminated. The pump will then start, or stop if it has
been running. To return to normal run simply press the SELECT button till the AUTO light is illuminated.
The V2 will automatically return to AUTO run after 30 minutes.
Roof Mo e displays the roof sensor temperature, a hot roof indicates that solar gain (heating) is
available, if left unattended in this mode the V2 will automatically return to AUTO run after 3 minutes.
Winter Mo e should be selected when the pool is not being used for extended periods. The pump will
be turned on for 3 minutes every day at the same time Winter Mode was selected. This will assist in the
systems off-season maintenance and save energy. To enter this mode press the SELECT button till the
WINTER light is illuminated. When a flow switch is used ensure the winter mode is activated during the
filter run times only. If the power is interrupted during winter mode the V2 will continue to count time
accurately.
Tropical Mo e is used to assist in cooling over heated pools. If the limit has been exceeded, which is
indicated by the limit light on, and the roof temperature drops below the limit temperature (usually
some time late at night) the pump will turn on and pump pool water to the roof to cool it down. The
pump will turn off when the pool water is cooled to the limit setting. To set this function press the
SELECT button till the TROP light is illuminated. To switch back to Summer Mode press the SELECT
button till the AUTO light is illuminated.
Retro-Fit (Booste ) Systems - Optional
When solar gain is achievable the V2 Controller detects constant water flow from the main filtration
system, the Pump light will flash for thirty seconds and then the solar boost pump will start. When filter
back washing is to be carried out the power to the V2 controller must be turned off. If Winter Mode is
to be selected, ensure that it is set during normal filter times and the main filter pump is running.
Clock this model is fitted with a settable 24 hour clock, see installers section if adjustment is required.
Night time is indicated by a flashing AUTO light.
OPERATION
The V2 will turn the pump on when the roof temperature is higher than the pool (pipe) temperature by
°C. When the pool temperature reaches the limit setting the limit light will turn on and the auto light
will flash, it will remain in this state for 4 hours. After 4 hours, and if solar heating is available the pump
is turned on for ~3 minutes to sample the pipe so an accurate pool temperature can be recorded, if
after 3 minutes the pool requires heating the pump will continue to run to heat the pool. If solar
heating is not available after the 4 hour wait a brief blink of the roof light is indicated. If the pump is
turned off due to the pool being at the set temperature limit, or if no heating is available on the roof
during day time operation, then the last accurate recorded pool temperature will be displayed for 6
hours from when the pump was last running. When the ~3 minute sample is active the pump/man light
will flash until this test is over. If an optional pressure switch is fitted the V2 will flash the pump light for
30 seconds when constant flow from the main filter pump is first detected, then start the booster pump.
In pressure switch mode no sampling occurs, the V2 waits until the pipe is below the set temperature
limit, indicated by a flashing auto light
