CONTROLLER MOUNTING:
The controller enclosure must be f rmly attached to a nearby sol d f xture by e ther the two mount ng lugs or d rect
attachment though the controller. If mount ng through the controller ensure the power cord s d sconnected from
the ma ns supply then remove the enclosure front cover by turn ng the four corner locks so each arrow po nts to
the ‘O’ marked on the front cover. Insert two mount ng screws d agonally through the oval holes n the enclosure,
ref t front cover and turn the four corner locks to the ‘I’ pos t on.
The power cable s 1.8m long and should be plugged d rectly nto a general power outlet, not nto an extens on
lead.
CIRCULATING PUMP(S):
The solar c rculat ng pump plugs nto the r ght hand 240Vac socket marked as SOLAR PUMP. The F ltrat on pump
plugs nto the left hand 240Vac socket marked as AUXILIARY.
The AUX ON. LED w ll be l t when the f ltrat on pump s operat ng and the SOLAR ON LED w ll be l t f the solar
pump s operat ng. The maximum allowable combined current for both pumps is 10 AMPS @ 2400W
Th s controller can be conf gured for the solar pump to be ndependent (std) or n ser es w th the f ltrat on pump
(retro-f t) for ser es retro-f t the solar pump s plumbed v a a T-p ece after the f lter.
TEMPERATURE SENSORS:
For retro-f t systems the pool sensor must be f tted n the suct on l ne before the take off Tee f tt ng for the solar
boost pump. For ndependent (standard) systems the pool sensor must be f tted nto the suct on l ne of the solar
boost pump, preferably n a pos t on out of d rect sunl ght. It s recommended that a 14.5mm hole be dr lled n the
PVC p pe, th s can be carr ed out us ng a Dontek PD01 gr nd ng dr ll or a small p lot hole can be dr lled and a
14.0mm dr ll-b t used sp nn ng n a counter clockw se d rect on to m n m ze the chance of shatter ng p pe. Insert
the grommet nto the p pe and gently push n the black sensor barb. The green sensor plug s to be f tted to the
plug socket marked POOL.
Roof sensor must be f tted nto a small p ece of rubber collector mater al away from the ma n collector but on the
same aspect. Keep n m nd that t s of the utmost mportance to keep the roof sensor cable as short as poss ble
as th s w ll ass st n the longev ty of the sensor and controller n the event of electr cal storm act v ty and power
surges. Sensor cables must not be run parallel to power cables and run lengths should be less than 50m. Cable
t es should be used to fasten the sensor cable to the cold water nlet p pe mak ng sure that the t es are
approx mately 10mm from PVC f tt ngs. Cable t es should be t ghtened only f rm, over t ghten ng can cause breaks
n the outer PVC f not careful. If the cable s to be run under ground a condu t should be used to protect the w re
and there s to be no cable jo ns w th n, condu t ends must be sealed to prevent water ngress Any excess cable
should be removed and re-fitted ensuring that the wire ends are tinned with solder The sensor plug s to be f tted
to the r ght hand socket marked ROOF.
DESCRIPTION:
The SL8-RTS s a solar controller that heats us ng a solar collector.
Solar & F ltrat on are all controlled by the t me clock and the r relevant sett ngs, heat ng s performed to the
temperature l m t plus ½°C and once that temperature s ach eved heat ng w ll no re-occur unt l the temperature
drops below the des red l m t by ½°C or unt l the 3 hour sample per od has elapsed and the temperature s at or
below the l m t. Th s controller s des gned for standalone operat on or for a retro-f t nstallat on where separate
plumb ng for the solar pump s not ava lable. In retro-f t the solar can be locked to f ltrat on to control the level of
chlor nat on.
SETTINGS MENU:
All tems on the LCD that flash are adjustable tems, use the Up or Down buttons to mod fy the adjustable tem.

2) FILTER TIMER
When the FILTER TIMER s selected the follow ng s d splayed;
SINGLE CYCLE
DUAL CYCLE
Select SINGLE CYCLE or DUAL CYCLE, S ngle Cycle runs the f ltrat on once per day, Dual Cycle runs the f ltrat on
tw ce per day.
S ngle & Dual cycle sub menu; Dual cycle sub menu;
FILTER CYCLE FILTER CYCLE 2 d FILTER CYCLE 2 d FILTER CYCLE
START TIME x:xx END TIME x:xx START TIME x:xx END TIME x:xx
Adjust the start t me and end t me for f lter cycle 1; f dual cycle was selected then also adjust the start and end
t me for the 2nd cycle.
Note1: that if dual cycle is selected, take care not to overlap the 2nd filter times with the first filter times as the
result will be one cycle per day
Note2: If a 24 hour filtration is required then set a single cycle with the start & end times the same (E g 12:00 –
12:00)
Note3: If the unit is configured as a retro-fit and solar is not locked to the filter pump (i e filter timer and/or aux
heating requirements) then any solar gain will force the filter pump to also turn on
Note4: Aux heater requirements will also override the filtration timer
Note5: In winter mode the 2
