CONTROLLER MOUNTING:
The controller enclosure must be firmly attached to a nearby solid fixture by either the two mounting lugs or direct
attachment though the controller. If mounting through the controller ensure the power cord is disconnected from the
mains supply then remove the enclosure front cover by turning the four corner locks so each arrow points to the ‘O’
marked on the front cover. Insert two mounting screws diagonally through the oval holes in the enclosure, refit front
cover and turn the four corner locks to the ‘I’ position.
The
power cable is 1.8m long and should be plugged directly into a general power outlet, not into an extension lead.
CIRCULATING PUMP:
The solar circulating pump plugs into the right hand 240Vac socket marked as SOLAR PUMP. The left hand 240Vac
socket marked as AUXILIARY supplies 240Vac at all times. The maximum combined current is 10 AMPS 2400W.
TEMPERATURE SENSORS:
The solar pool sensor must be fitted into the suction line of the solar boost pump, preferably in a position out of direct
sunlight. The aux pool sensor must be fitted into the suction line before the pool pump (filtration 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 solar
pool sensor plug is to be fitted to the plug socket marked POOL. The aux pool sensor plugs into the socket marked
RELAY1 (Black to NO, White stripe to C).
Roof sensor must be fitted into a small piece of rubber collector material away from the main collector but on the same
aspect. Keep in mind that it is of the utmost importance to keep the roof sensor cable 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 marked ROOF.
FLOW SWITCH
:
The flow switch must be fitted after the pool/spa valve into the pool return line, the arrow on the flow switch indicates
the direction of water flow. The green plug will go into the FLOW socket on the controller.
HEATER INTERLOCK:
The heater interlock cable connects in-series to the existing internal flow or pressure switch inside the heater,
connection varies depending on model, contact heater manufacturer for details, maximum switching capability of the
controller is 5 AMP at 32VAC MAX! If the heater exceeds this then the 240V switching option is to be fitted.
The green plug on the heater interlock cable connects to the socket marked RELAY2 (NO/C).
OPTION - IHP:
An optional IHP connects to the DATA socket of the controller; ensure to match the colours to avoid damage. Do not
run near 240Vac wiring.
DESCRIPTION:
The Solar is for heating the pool only and will operate as a standalone system. If water flow is detected by the flow
switch then the aux pool temperature sensor is used; and if there is no solar gain the aux heater will be enabled if
within the selected timeframe of heat demand and only if the pool temperature is below the aux limit setting.
If there is solar gain available then the heater will run in conjunction with the solar but will turn off when the roof
temperature exceeds 15°C above the solar temperature limit setting. When the flow switch detects that water flow has
stopped going into the pool then the heater is enabled to heat the spa to the higher temperature limit as set at the aux
heater.
