achieves temperature limit during the 2
heat cycle then it will start an economy/sleep
mode, which will prevent the pump from
starting for the rest of the day.
MANUAL PUMP MODE
Holding the UP button to go above 40°C will
toggle the pump from Off to On or vice versa,
Manual mode will time out after 30 minutes of
being selected, with a default temperature
limit of 30°C
WINTER MODE
Holding the DOWN button to go below 20°C
will set the unit into WINTER mode, on
selection of winter mode the pump will run for
3 minutes and will repeat this every day at the
same time unless the power fails. Should
there be an interruption to power then an
exception takes place to prevent the pump
starting at night, the sensors are tested to
check that the roof sensor is 5°C or more
above the pipe sensor, if this temperature
condition is not met the display will show
"waiting for roof to warm", once the pump
starts the controller will wait 24 hours to
perform another unconditional flush of the
system.
SUMMER MODE
Summer mode is the default mode of
operation; if tropical mode has been selected
you can change back to summer mode push
both buttons and when SUMMER is displayed,
released the buttons and use the up or down
buttons to set the desired temperature. The
controller will automatically heat the pool to
this temperature when solar conditions are
favourable.
TROPICAL MODE
To activate tropical mode, push and hold both
buttons and when "TROPICAL" is displayed,
release the buttons and use the up or down
button to set the desired temperature. In
tropical mode the controller will attempt to
heat the pool, if the pool exceeds the
temperature limit while heating then the
controller turns off the pump and waits for

nd
the roof to cool so the controller can cool the
pool down by dissipating the heat on the cold
roof (most likely to occur at night). In tropical
mode the controller attempts to keep the
pool at the temperature limit by either
heating or cooling as required.
NOTES

The sensor cable with the red trace is the
3.
positive and is usually fitted to the right
hand side of the plug when looking at the
plug screws, incorrect polarity may be
displayed as a short circuit fault.
If the controller has stopped pumping and
4.
is displaying a higher temperature than
expected it may be caused by a pump
which is failing to prime, check the pump
and if necessary prime the pump as per
the pump manufacturers' instructions
then reset the controller by turning it
off/on.
