Optional Pressure Switch & Connection
Some solar heating installations use a “booster” pump to circulate pool
water through the roof collector system and do not have a separate solar
circuit to and from the pool.
These installations require the optional pressure switch (P/N M6601),
whichwillonlyallowtheboosterpumptoturnonifthemainltrationpump
isrunningandwaterisavailabletotheboosterpump.Withoutthissafety
system, damage to the booster pump may occur.
1. Fit pressure switch at suitable point on pool return. If return does not
haveenoughpressuretpressureswitchbetweenpumpandlter.The
pressure switch should be tapped into a point where the pipe enters a
ttingtoallowagoodthreadlength.Tapsizeis1/8”NPT.Takecarenot
to damage threaded end.
2. Connect 5 metre sensor cable to pressure switch and plug into marked
socket on the underside of the controller.
3. PLEASENOTE:IfaFLOWfaultisdetected,whichisindicatedby
theashingoftheredPUMPRUNLED,thenthesolarpumpwillbe

owfaultisrectied.AsthesolarpumphasaminimumRUNtimeof10
minutes and a minimum OFF time of 10 minutes after it has operated,
thesolarpumpmayrunimmediatelyfollowingtheowfaultbeing
