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 1.8m long and should be plugged directly into a

general power outlet, not into an extension lead.

Pressure Switch or Flow Switch for Retro-Fit (Boosted) 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 should be removed and re-fitted ensuring

that the wire ends are tinned with solder. 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 soldered and this includes 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 88 indicates wrong polarity connection or short-circuited cable or sensor.

A display of 89 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.
