SWIM SPA - CONTROLS: SWIM SPA BEHAVIOR
PUMPS
Press the “Jets 1” button once to turn pump 1 on or off, and to shift between low- and high-
speeds if equipped.
If left running, the pump will turn off after a time-out period. The pump 1 low-speed will
time out after 30 minutes. The high-speed will time out after 15 minutes.
On non-circ systems, the low-speed of pump 1 runs when any other pump is on. If the swim
spa is in Ready Mode (See page 39), Pump 1 low may also activate for at least 1 minute every
30 minutes to detect the swim spa temperature (polling) and then to heat to the set tempera-
ture if needed. When the low-speed turns on automatically, it cannot be deactivated from the
panel, however the high speed may be started.
FILTRATION AND OZONE
Pump 1 low and the ozone generator (if so equipped) will run during filtration.
The system is factory-programmed with one filter cycle that will run in the evening (assuming
the time-of-day is properly set) when energy rates are often lower. The filter time and dura-
tion are programmable. (See page 43)
A second filter cycle can be enabled as needed.
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) activate to provide freeze protection. The pump(s) will run either continuously or
periodically depending on conditions.
