INITIAL START-UP
Before applying voltage to power-up your hot tub, it is very
important that you understand the sequence of events that
occur when the system is activated in order that the pumps
can be primed efficiently and damage to the pumps can be
avoided.
At initial power-up, this display will appear,
and the system will show 4 sets of
numbers in succession (ie. 100 then 113
then 13 then 240). These numbers
represent the current software revision,
and the system input voltage.
After the initial software indicators are
shown, this display will appear. This display
is indicating that the system is in PUMP
PRIMING MODE. This mode will last for
4 to 5 minutes before automatically
exiting
Flashing
operation mode. You can also manually exit the PUMP
PRIMING MODE after the pumps are primed (see below).
While in this mode, the heater circuit is disabled to
allow the priming process to be completed without the
possibility of energizing the heater element during low flow
or no flow conditions. The system will not automatically
activate any of the functions, however, by pushing the
pads on the topside control, the pumps can be manually
activated
Definition: 'Priming' a pump is a term used to describe the
process in which air trapped in the plumbing and pump
wet-end (referred to as an 'air lock') is released, allowing
the pump to move water efficiently through the plumbing
system and to the jets.

Once pump priming has been successfully completed, press
the pads to turn off the pumps. Next, manually exit
PRIMING MODE by pressing either the
pad. If you do not manually exit Priming Mode, it will
automatically terminate after 4 to 5 minutes. Be sure that
the pumps have been primed before exiting this mode.
TEMPERATURE CONTROL
FUNCTIONALITY AND ADJUSTMENT
After you manually exit or the system automatically exits
PRIMING MODE, your hot tub will automatically heat to
the factory preset default temperature of 100˚F. The topside
panel will briefly show the default temperature, and then
the display will appear as follows:
Note that the water temperature is not
yet displayed, as the system requires
approximately 2 minutes of water flow
through the heater to determine
temperature. This is referred to as 'polling'
and is indicated on the display by the
