Dontek V2 Series Installation Instructions Manual

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 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 and the Pressure Switch is to be fitted between the
main Filter Pump and Filter in a vertical or horizontal 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 Switch is to be used the controller must
have this function turned on. To do this ensure the power is turned off to the unit, press and
hold the up and down buttons together while the power is switched on, release and a 33 will
briefly be displayed followed by a 44 for normal summer mode or 55 for tropical mode. To
switch off the pressure switch mode simply repeat the process and the unit will display the
44 or 55 only.
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 guttering 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 run. 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, ends of conduit 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.
Fault Diagnosis
In the event of a sensor or cable 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. (When powered up with up button
pressed)
A flashing display of 44 or 55 may also indicate an over extended, coiled sensor cable or a corrupt sensor.
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.
