Pump Faults
Ensure the controller has working sensors; otherwise the pump will not operate.
FAULT
REASONS/SOLUTIONS
PUMP WILL NOT START
The pump will only ever run for the purpose of automatic heating if the pool is below the
temperature limit and solar conditions can provide heating. The pump may also run for a
flush in standby mode or for manual mode operation. If the controller reports that the pump
is off, then press select to enable manual mode. The relay inside should click and the pump
should operate. If the pump does not operate, then plug the pump into a power point and
test operation. If the pump is okay, then the controller requires repair.
PUMP WILL NOT STOP
Turn off power to the controller and ensure the pump stops. If the pump continues to operate,
then unplug it from the power point and connect it to the 240V socket marked PUMP at the
bottom of the controller.
Apply power to the controller and if the pump starts instantaneously before temperatures are
displayed, then there may be a fault with the controller. Since the controller shouldn’t run when
there is a sensor fault, disconnect the roof sensor and wait for approximately 30 seconds. If the
pump continues to run, then the controller requires repair.
POOL NOT HEATING
If the controller has stopped pumping and 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.
RTC-FAIL
This can occur if the unit has been turned off for a prolonged period of time. Leave the unit on
for 30 seconds and this will allow charging of the supercapacitor. Next, turn it off for 30 seconds
before turning it back on.
