ER-5 POOL TOO HOT
Problem: Pool over-temperature. Temperature sensor is reading 45°C or above.
Cause: High ambient temperatures (most likely during summer months) have caused the water
temperature to rise above its set point. Excessive filtration time, pump has been operated for
extended periods of time with the spa cover still on.
Solutions:

Turn off mains power, remove the spa cover and allow the spa to cool down before turning
back on.

Check the daily filtration time settings and reduce the filtration time if required. (Refer to
SpaNet SV Mini user manual).

Check spa cover is not resting on the touchpad buttons causing the pump to start when cover
is on. Use key lock function to lock keypad buttons when the spa is not in use.

Contact your spa pool supplier if the problem persists.
ER-6: 12V OVERLOAD
Problem: 12V port current draw over 1A limit.
Causes: Total 12V current drawn by touchpad, lights, expansion ports and temperature sensor is
excessive, 12V power supply is overloaded, too many LED bulbs installed, faulty LEDs.
Solutions:

Turn off spa and restart to see if the problem reoccurs.

Systematically unplug LEDs, touchpad and expansion port loads from the control box PCB (one
by one) to identify the faulty 12V device.

Contact your spa pool supplier if the problem persists.
