PumPs
Press the "Jets 1" button once to turn pump 1 on or off, and to shift between low- and high-

every 30 minutes to detect the spa temperature (polling) and then to heat to the set temperature
if needed. When the low-speed turns on automatically, it cannot be deactivated from the panel,
however the high speed may be started.
Circulation Pump
The 24 hour circ pump operates continuously 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).
FiltratioN aNd ozoNe
On non-circ systems, Pump 1 low and the ozone generator will run during filtration. On 24 hour
circ systems, the ozone will run with the 24 hour circ pump.
The system is factory-programmed with two filter cycles that will run 10 minutes after power-up.
The filter duration is programmable.
At the start of each filter cycle, Pump 2 (if there is one) will run briefly to purge its plumbing to
maintain good water quality.

Freeze ProteCtioN

If the temperature sensors within the heater detect a low enough temperature, then the pump(s)
automatically activate to provide freeze protection. The pump(s) will run either continuously or
periodically depending on conditions.
