– Dolphin II Address
When set to “ ”, no addressing is used. Use this setting
for a Dolphin I, or for a Dolphin II which is set for no address
(which is the Dolphin II factory default). When set to
“ ” through “ ”, the number is the address (see your
Dolphin II manual for details).
Editing User Preferences
View the setting.
The left two characters (before the decimal point) tell
you what setting you’re viewing or editing, the right most
character (after the decimal point) tells you the value of that
setting (for example, “ ” for Yes or “ ” for No).
If the value is flashing, you’re editing it. If the value is not
flashing, you’re just viewing it.
Press “Jets 1” to switch editing of the value on (flashing) or
off (not flashing). Once you’re editing the value (it’s flashing),
use the “Cool” or “Warm” buttons to change the value to the
one you want.
After you change the value, you must press “Jets 1” again to
stop the flashing before the change will register, and before
you can view or edit another setting.
If you don’t interact with the menu for more than 30 seconds,
it may time out.
If you press “Light” to back out of the menu, or pause
long enough for it to time out, while a value was flashing,
the changes you were making to that setting are not
remembered. But changes you previously made to other
settings will be in effect.
Any User Preferences that you change will stay in effect
“forever” or until you change them again (unless the spa’s
“persistent memory” is reset by a service technician), and
will override the factory defaults for those settings.
