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 filtration 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 fit pressure switch between pump and filter. The
pressure switch should be tapped into a point where the pipe enters a
fitting 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 flashing of the red PUMP RUN LED, then the solar pump will be
switched off. The red PUMP RUN led will continue to flash until the
flow fault is rectified. 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 flow fault being
rectified or wait for a maximum of 10 minutes before operating.
