Understanding heat pump error codes
HEAT PUMP ERROR CODES
If an optional heat pump is fitted and a heat pump fault condition is detected a warning
message is scrolled across the touch pad LCD every 60 seconds and the heat pump is
disabled.
Spa operation will continue however the spa will now heat with the inbuilt SV electric
element and there will be no ability to cool the water. The heat pump warning message
will continue to scroll every 60 seconds, and the heat pump will remain disabled until the
mains power is turned OFF and back ON again.
If after resetting mains power the fault condition persists please contact your spa
reseller and report the warning message that is shown. A list of the fault conditions and
warning messages are detailed below for reference.

SERVICE REMINDER MESSAGES
Certain spa manufacturers will choose to take advantage of the inbuilt service
timer reminders available within the SV controller software. Maintenance
reminders such as "SERVICE FILTERS" can be programmed to scroll across the
screen every 60 seconds after a certain time period has elapsed.
If your keypad display begins scrolling a service reminder every 60 seconds
this message can be cancelled/reset by pressing the OK button whilst the
service message is scrolling.
SERVICE FILTERS
A default service reminder scheduled to occur every 2 or 4 weeks. This reminder
is to prompt the spa owner to thoroughly clean and service their spa filters.
Depending on type of filter cartridge(s) installed the filters will either require
cleaning, soaking in a filter cartridge degreaser solution or replacing. Refer to
spa reseller/manufacturer for details on type of filter cartridge(s) installed and
recommended cleaning methods.
