Mode of Operation
Pressing the SELECT button once will display the current mode of operation, pressing it again or holding
it will select the next available mode of operation.
The available modes are SUMMER, MANUAL, TROPICAL or WINTER.
Summer Mode
is the normal operating mode for heating the pool.
Winter Mode
of operation is for off-season maintenance or if pool heating is not required (AWAY MODE).
This is a better option than turning off the controller as it will flush treated pool water through the solar
system as well as prolong pump bearing and mechanical seal life. The pump will run for 3 minutes each
day from when the winter mode was selected or at 10am if the time-clock mode was selected.
Tropical Mode
is for situations where the pool water overheats due to direct heating from the sun,
beyond the set limit. When the roof is 4°C cooler than the pool temperature, the pump is started (this will
most likely occur at night) and will attempt to cool the pool to 1°C above the temperature limit. Normal
heating will occur the next day if the pool drops below the temperature limit by 1°C.
Manual Mode
is for testing the pump installation on a cold or cloudy day. Once manual mode is selected
the pump will start if it has been off, or stop if it has been on (running). After 30 minutes manual mode
will time-out and return to summer mode with a default temperature limit of 30°C
Settings Mode
is for setting the unit into time-clock operation.
When you select this option you will be asked if you wish to use the clock feature (CLK? ON/OFF).
If you select OFF then the controller will not work as a time-clock model and will allow the solar pump to
run whenever there is solar heating available. If you select ON you will be prompted to set the time of
day, the controller will work in time-clock mode and the solar pump is prevented from starting outside of
the set hours (unless tropical mode is selected). Set the time of day in 24 hour format, note there is an
AM/PM indication to avoid incorrect settings. Seconds are automatically set to zero.
Once the time is set select the START hour from 6am until 12noon, default is 9am which means the solar
pump cannot start before 9am.
Now select the END hour from 15:00 (3pm) until 21:00 (9pm), default is 19:00 (7pm) which means the
solar pump will stop at 7pm.
Installer Settings - Adjustable differential and anti-freeze feature
Special note: Adjusting these values to any setting other than the defaults may adversely affect the
performance of this controller.
To select these features, hold the DOWN button then press SELECT. When you select this option you will
be prompted to set the solar gain start temperature (RUN° x) this setting allows the pump to start if the
roof temperature exceeds the pipe temperature by this value, adjust with the UP/DOWN button, press
