INSTALLATION
MS3D is weather resistant, however it should be mounted in a sheltered position
where it is not exposed to direct weather, splashing or spray from the pool or
filtration equipment. Electrical building regulations specify that MS3D must
not be mounted within 3.5 metres of the pool.
Fix the unit to a wall or post, within 1.5 metres of a 240 volt outlet and within 2
metres of the Solar pump. Mounting points are provided on the back. Two sets of
temperature sensor cables are supplied. One short (3m) for the pool and one long
(24m) for the roof. This Solar Control unit Must be installed in the upright position.
The hole size required for the pool sensor grommet is 12.5mm (1/2 inch) diameter.
Avoid cutting the sensor lead (excess can be neatly coiled). If the cable is
cut, it must be reconnected with the POSITIVE (stripe) to the POSITIVE,
and the NEGATIVE (no stripe) to the NEGATIVE. Do not place any wire
joins under ground.
POWER CONNECTION
Power is supplied through a standard 240 volt lead. A piggyback socket is provided
on the lead if you need to run the filter pump and this MS3D from the one power
outlet. Power for the solar pump comes from the socket on the bottom of the MS3D
Maximum Pump rating – 1.5HP
ONLY THE SOLAR PUMP IS TO BE CONNECTED TO THE CONTROLLER
OUTLET .
MORE THAN THIS WILL DAMAGE THE ELECTRONICS AND VOID YOUR
WARRANTY.
OPERATION
AUTOMATIC MODE
. For full automatic operation, simply plug it in and switch on.
When the MS3D senses the sun’s heat it compares it to the pool’s temperature and
your preset "comfort " temperature and decides when to heat the pool. Whenever
the unit is powered up, there will be a delay of 2 minutes before the solar pump is
activated. The unit will then run for at least 6 minutes to reset the pool temperature
sensor.
Comfort Temperature Adjustment
Adjustment of the comfort level is achieved by pressing either the "+" or "–"
buttons. The first operation will simply display the present comfort temperature. Any
further operation of the buttons will increase or decrease the setting. The setting
will automatically change if either button is pressed and held down.
This temperature will be stored permanently in memory, even with power off.
DISPLAY MODE.
To read roof , pool and comfort temperature settings, press the
"DISPLAY" button. The display will cycle through the three settings showing an "r"
for roof , a "P" for pool or "L" for Last and a "C" for comfort.

operate the solar system daily throughout the colder months. By using this facility
you will extend the life of your solar heating by preventing pump seizure and drying
of chemical build up in the collector.
