Er-5 Pool Too Hot

Problem: Pool over-temperature. Temperature sensor is reading 45°C or above.


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.


  • 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.

If the problem persists, contact your spa pool supplier.
