Circ Pump (optional)
If your system is equipped with a circ pump, it may be
configured to work in one of three different ways:
1) The circ pump operates continuously (24 hours) with the
exception of turning off for 30 minutes at a time when
the water temperature reaches 3°F (1.5°C) above the set
temperature (most likely to happen in very hot climates).
2) The circ pump stays on continuously, regardless of water
temperature.
3) The circ pump will come on when the system is checking
temperature (polling), during filter cycles, during freeze
conditions, or when another pump is on.
Ozone (optional)
On most systems, the ozone generator (if installed) runs
during filter cycles (except when pump 1 is operating at high
speed on a non-circ system) and during clean-up cycles. On
some systems, the ozone generator operates whenever the
pump runs.
If your system is configured with the optional ozone suppress
feature, the ozone generator will turn off for 1 hour any time
a function button (Jets 1, Jets 2, Blower, etc.) is pressed.
Displaying Info About Your Spa
There are several pieces of information about your spa that
can be called up from the panel, but are only needed in
special cases.
To access this information, press “Cool” or “Warm” then
“Jets 1”, then “Light”. (Each press must be within 3 seconds
of the previous press.) Then press “Cool” until you see “
” on the display. Press “Jets 1” to see the SSID (a series of
3 numbers, such as 100 133 10, which indicates the precise
revision of the software in your spa), followed by the Mach
software version number (such as 2.1), followed by “
” and then your spa’s network ID number (consisting of both
letters and digits displayed in 5 steps).
If you need to see this series of numbers again, and “ ”
is once again on the display, just press “Jets 1” again.
When done, press the “Light” button (more than once if
necessary) until you see the normal temperature display.
User Preferences
There are several aspects of spa operation that you can
customize using the User Preferences submenu.
Press “Cool” or “Warm” then “Jets 1”, then “Light”. (Each press
must be within 3 seconds of the previous press.) At this
point, if “
” is not showing on the display, press “Cool”
until you see “ ” on the display. Then press “Jets 1” to
enter the User Preferences submenu.
Once in the User Preferences submenu, press “Cool” or
“Warm” to cycle between these settings:
– Suppress Reminders
When set to “ ”, reminders are never displayed on the

– 24-hour Time Display
When set to “ ”, time is displayed in 24-hour (military)

(am/pm) format (12:00 is midnight, 11:00 pm is one hour
before midnight).
– Clean-up Cycle Duration (some systems only)
When set to “ ”, Clean-up Cycles are disabled. When set
to “ ” through “ ”, the number indicates how many
hours each Clean-up Cycle will run.

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).
