Background:
In some situations the SV controller may not operate as expected or display unusual characters or numbers on the touch pad LCD display. This may be a result of the software memory (EEPROM chip) within the SV controller being corrupted.
If you ever discover a SV controller not operating as expected, be it pumps not working, blowers only working for a few seconds, strange or blank displays etc… you should always try the below procedure to reset the software (EEPROM chip) first before reporting a RMA fault. In most situations the EEPROM reset will solve the problem.
How to reset the SV controller software (EPRM)
Step 1 (SV Series)
To carry out an Eeprom reset, access the OEM config menu on an SV controller by pressing and holding the “Air Blower” and “Water Clean” buttons simultaneously until the display shows “C.LMT” (refer fig. 1).
Step 1 (SV Mini Series)
SV Mini controllers feature a hidden OEM configuration menu which allows customisation of certain important spa control settings. To access the OEM config menu on a SV Mini 1 press and hold the hidden buttons (fig.1 – shown by the red dotted circles aside) simultaneously until display shows L.SHD. For SV Mini 2 press and hold the PUMP C + BLOWER buttons simultaneously (fig.2)
Step 2 (Both SV & SV Mini Series)
Use the DOWN arrow button to navigate through the configuration menu items until “EPRM” is displayed.
Step 3
When “EPRM” is displayed on screen press the OK button to execute the software reset. The display will very briefly flash “ESET” as the reset process takes place.
Step 4
Once the display returns to the temperature, it is best practise to then reset the mains power (i.e. turn off/on) to reboot the control after the EPRM factory reset has been performed.
Note:
All user software setting values are reset to factory default including the Set temperature of 38°C. Electrical settings in the configuration menu such as C.LMT (current limit) and L.SHD (load shed) settings will NOT be adjusted as they have been customised to suit the particular spa pool and its available power supply by the spa manufacturer or installing electrician.
