SWIM SPA CONTROLS: V174S & V174K
Change the water
May appear on a regular schedule, i.e. every 90 days. Change the water in the spa on regular ba-
sis to maintain proper chemical balance and sanitary conditions. You may want to set a reminder
to purge, drain and fill your swim spa every 90 days to avoid total dissolved solids buildup in your
water which can render your sanitizer ineffective.
Change the filter
May appear on a regular schedule, i.e. every 180 days. Filters should be replaced occasionally to
maintain proper spa function and sanitary conditions. Filters should be inspected for wear, tear or
damage every 180 days to assure your swim spa is functioning properly.
MISCELLANEOUS MESSAGES
Set the Time-of-Day
When a control system that displays this message is powered On, its time-of-day is initialized to
12:00 PM. Setting the proper time-of-day is important for determining filtration times and other
background features.
Communications error
The control panel is not receiving communication from the System. This can appear briefly during
system start-ups. This is normal. If it does not go away quickly, Call for service.
Test software installed
The Control System is operating with test software. Call for service.
MESSAGE NOTES
Some messages include the "Call for Service" text as it requires a service technician to fix the
problem.
If the panel is locked and a message alert appears, you will be taken to the Lock Screen (where
you will need to Unlock the panel) before you can clear the message.
Touching the Error/Warning/Reminder/Info Icon on the Message Screen will take you to the
System Information Screen to allow for troubleshooting over the phone or for a field service tech
to better understand what is going on. Exiting the System Information Screen will take you back
to the Message Screen in that situation.
