Page 1 of 4
DESCRIPTION:
The SL8 RR 2PUMP is a swimming pool con roller ha hea s a swimming pool by pumping pool wa er hrough solar
collec or panels.
If solar gain is available he solar sys em will hea he pool o he solar limi (sol limi ). Solar has a ime lockou ha
preven s hea ing ou side of he ime se (defaul 09:00 – 19:00, see no e 5).
CONTROLLER MOUNTING:
The con roller enclosure mus be firmly a ached o a nearby solid fix ure by ei her he wo moun ing lugs or direc
a achmen hough he con roller. If moun ing hrough he con roller ensure he power cord is disconnec ed from he
mains supply hen remove he enclosure fron cover by urning he four corner locks so each arrow poin s o he ‘O’
marked on he fron cover. Inser wo moun ing screws diagonally hrough he oval holes in he enclosure, refi fron
cover and urn he four corner locks o he ‘I’ posi ion.
The power cable is 1.8m long and should be plugged direc ly in o a general power ou le , no in o an ex ension lead.
CIRCULATING PUMP(S):
The solar circula ing pump plugs in o he righ hand 240Vac socke marked as SOLAR PUMP. The lef hand 240Vac
socke marked as AUXILIARY will con rol he second pump which s ar s 3 seconds af er he SOLAR PUMP. The
maximum combined curren is 10 AMPS 2400W.
FLOW SWITCH:
This con roller is no fi ed wi h a flow swi ch, ins ead i s hard wired in ernally o have permanen flow, be aware ha a
message will appear for 30 seconds indica ing ha i is wai ing for prime 30 before solar s ar -up.
TEMPERATURE SENSORS:
The pool sensor mus be fi ed in o he suc ion line of he solar boos pump, preferably in a posi ion ou of direc
sunligh . For re ro-fi sys ems he pool sensor mus be fi ed in he suc ion line before he ake off Tee fi ing for he
solar boos pump. I is recommended ha a 14.5mm hole be drilled in he PVC pipe, his can be carried ou using a
Don ek PD01 grinding drill or a small pilo hole can be drilled and a 14.0mm drill-bi used spinning in a coun er
clockwise direc ion o minimize he chance of sha ering pipe. Inser he gromme in o he pipe and gen ly push in he
black sensor barb. The green sensor plug is o be fi ed o he plug socke marked POOL.
This uni has been designed o elimina e he need o run a empera ure sensor cable from he solar con roller o he
roof, his is replaced by a Solar Powered roof empera ure ransmi er ha only ransmi s when in direc sunligh , and
a receiver ha calcula es he roof and pool empera ure urning on he solar pump when required.
As he uni opera es in a UHF radio band, reflec ions and moving objec s can cause a ransmission o be corrup ed
wi h a subsequen indica ion “ROOF SIGNAL NOT RECEIVED” on he display. Up o 10 ransmissions can be missed
(and las valid reading is kep for 10 minu es) before pump ac ion will occur and he solar pump will urn off. If his
occurs, and if he solar condi ions are s ill favorable, he solar pump will no urn on again and resume normal
opera ion unless i has received a valid ransmission.
The remo e roof ransceiver ob ains i s opera ing power from a solar panel, i will no opera e if here is no sun or if
here is significan cloud cover. Obviously solar hea ing would no occur in such condi ions.
Due o he possibili y of recep ion ghos ing and elec rical in erference he Transmi er may be required o be moved o
an al erna ive posi ion, his may be as li le as wo me ers and keep in mind ha he roof sensor cable may be
ex ended 20 me ers if required. The main con roller should be moun ed away from o her elec rical appliances as far as
possible o reduce he chance of in erference. If he uni is o be ins alled in a me al shed here may be recep ion
issues and he con roller may need o be op ioned wi h a remo e an enna or moved ou side. A Power subs i u e cable
is supplied for ins alla ion es ing on cloudy days – Simply clip a 9Vol Transis or Ba ery on o he Ba ery Snap
supplied and subs i u e he lef hand green plug marked PV. Remember o refi original plug when es ing is over.
