SL8-RTA – INSTRUCTIONS

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(S):

The solar circulating pump plugs into the right hand 240Vac socket marked as SOLAR PUMP. The Filtration pump
plugs into the left hand 240Vac socket marked as AUXILIARY.
The AUX ON. LED will be lit when the filtration pump is operating and the SOLAR ON LED will be lit if the solar
pump is operating. The maximum allowable combined current for both pumps is 10 AMPS @ 2400W.
This controller can be configured for the solar pump to be independent (std) or in series with the filtration pump
(retro-fit) for series retro-fit the solar pump is plumbed via a T-piece after the filter.

HEATER INTERLOCK:

The heater interlock cable connects to the green socket marked RELAY1 which switches on the NO/C contacts
when the heater is to be turned on. The other end of the heater interlock cable connects in series to the heater's
flow or pressure switch circuit. If the heater's flow/pressure switch circuit is 240Vac then a special switchbox is to
be connected (Option SB02).

VALVE OPTION:

The valve option can only be added at time of manufacture and is connected to the green socket marked VALVE.
A valve can be used for selecting or bypassing the solar collector when heating with an auxiliary heater in the
independent plumbing configuration. The valve can also be used for selecting or bypassing the solar collector
instead of using a solar pump in the retro-fit plumbing configuration.
Temperature SENSORS:
For retro-fit systems the pool sensor must be fitted in the suction line before the take off Tee fitting for the solar
boost pump. For independent (standard) systems the pool sensor must be fitted into the suction line of the solar
boost pump, preferably in a position out of direct sunlight. 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
plug socket marked POOL.
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 should 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.

DESCRIPTION:

The SL8-RTA is a solar controller that heats using a solar collector and a heat pump or gas heater.
Solar, Filtration and heating via an auxiliary heater are all controlled by the time clock and their relevant settings,
heating is performed to the temperature limit plus ½°C and once that temperature is achieved heating will no re-
occur until the temperature drops below the desired limit by ½°C or until the sample period has elapsed and the
temperature is at or below the limit. This controller is designed for standalone operation or for a retro-fit
installation where separate plumbing for the solar pump is not available. In retro-fit the solar can be locked to
filtration and heater timers to control the level of chlorination.
