SLH7 SV – INSTRUCTIONS
Page 1 of 4
CONTROLLER MOUNTING:
The controller enclosure must e firmly attached to a near y solid fixture y 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 y 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 ca le is 1.8m long and should e plugged directly into a general power outlet, not into an extension lead.
CIRCULATING PUMP:
The circulating pump plugs into the right hand 240Vac socket marked as PUMP and will e operating as indicated y
the PUMP ON LED. The left hand 240Vac socket marked as Auxiliary provides continuous power as indicated y the AUX
ON. LED. The maximum allowable combined current for both sockets is 10 AMPS @ 2400W
HEATER INTERLOCK:
The heater interlock ca le connects to the green socket marked RELAY1 which switches on the NO/C contacts when the
heater is to e turned on. The other end of the heater interlock ca le connects in series (daisy chain) to the heater’s
flow or pressure switch circuit (refer manufactures instructions). If the heater’s flow/pressure switch circuit is 240Vac
then DO NOT connect the RELAY1 ca le directly to the heater, a KIT02 needs to e used which is supplied with an
external 240V rated relay which will need to e connected in series with the flow/pressure switch y a licensed
elect ician. Set the temperature setting on the heater 5°C a ove the desired water temperature to allow the SLH7 to
e in control without conflict.
VALVE:
The valve actuator is connected to the green socket marked VALVE, wired as descri ed on the la el. The valve is used
for selecting or ypassing the solar collector. Wire as per the la el on the controller.
TEMPERATURE SENSORS:
The pool sensor must e fitted into the suction line of the pump, prefera ly in a position out of direct sunlight. It is
recommended that a 14.5mm hole e drilled in the PVC pipe, this can e carried out using a Dontek PD01 grinding drill
or a small pilot hole can e drilled and a 14.0mm drill- it 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 lack sensor ar . The green sensor
plug is to e fitted to the plug socket marked POOL.
Roof sensor must e fitted into a small piece of ru er collector material away from the main collector ut on the same
aspect. Keep in mind that it is of the utmost importance to keep the roof sensor ca le as short as possi le as this will
assist in the longevity of the sensor and controller in the event of electrical storm activity and power surges. Sensor
ca les must not be run parallel to power cables and run lengths should e less than 50m. Ca le ties should e used to
fasten the sensor ca le to the cold water inlet pipe making sure that the ties are approximately 10mm from PVC
fittings. Ca le ties should e tightened only firm, over tightening can cause reaks in the outer PVC if not careful. If the
ca le is to e run under ground a conduit must e used to protect the wire and there is to e no ca le joins within,
conduit ends must e 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 e fitted to the right hand socket marked ROOF.
DESCRIPTION:
The SLH7 SV is a swimming pool controller that heats a swimming pool y the use of an auxiliary heater or if solar gain
is availa le an automatic valve will divert water to the solar collectors.
The auxiliary heater (gas or heat pump) has a temperature limit setting (AUX LIMIT) and run time settings, the pool
will e heated to this limit y the auxiliary heater, in situations of high solar gain the controller activates an energy
saver mode, in energy saving mode the auxiliary heater is switched off regardless of pool temperature when the roof
temperature exceeds 15°C a ove the AUX LIMIT, once the energy saver mode is active the auxiliary heater remains
OFF until the roof temperature drops elow the AUX LIMIT plus 10°C.
If solar gain is availa le the solar system will heat the pool to the solar limit (SOL LIMIT).
Solar has a time lockout that prevents heating outside the hours of 08:00 to 19:00 and can e changed (see note 6).
An automatic divert valve will divert water to the solar collectors when there is enough solar gain and will ypass the
collector when solar heating is no longer availa le.
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 elow the desired limit y ½°C or until the sample period has elapsed and the temperature
is at or elow the limit.
