SPA BEHAVIOR
PUMPS
On the Spa Screen, select a "Jets" button once to turn the pump 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 (15
minutes at high speed).
NON-CIRCULATION SYSTEMS
To monitor current water temperature, the system will automatically activate Pump 1 at the
low-speed setting as needed. If the spa is in Ready Mode, Pump 1 low may activate for at least
1 minute every 30 minutes to monitor the spa water temperature (known as polling) and begin
to heat if water temperature has dropped below the set temperature. If the water temperature
remains consistent over long periods, and does not decrease, the M8 technology in your spa will
actively adapt these polling intervals to be less frequent. If the water temperature conditions are
very stable, M8 will gradually increase time between the intervals, up to 2 hours. If the water
temperature starts dropping significantly, the system will check the water temperature (poll) more
frequently, reverting the interval back to every 30 minutes. It will also reset the intervals back to
30 minutes whenever the user interacts with the system (such as activating equipment, changing
heating modes and modifying the set temperature).
Pump 1 runs automatically, at the low-speed setting, when any other pump is turned on (if
equipped) so that the system can monitor the spa water temperature.
When the low-speed of Pump 1 turns on automatically for either temperature polling, heating or
filter cycles, it cannot be turned off at the control panel. However, the high speed setting on the
pump can be turned on.
CIRCULATION PUMP MODES
If the system is equipped with a circulation pump, it will be configured to work in one of two different
ways depending on the control system software. The circulation pump mode cannot be changed.
1. Most circulation pumps operate 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 warm climates or if set temperature is lowered/set below the current
water temperature). This is the typical mode for most spas with a dedicated circulation pump.
2. A programmable circulation pump will come on when the system is checking temperature
(polling), during filter cycles, during freeze conditions, or when another pump is on.
FILTRATION AND OZONE
On non-circulation systems, Pump 1 low and the ozone generator will run during filtration.
On circulation systems, the ozone will generally run with the circulation pump.
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 duration are
programmable. A second filter cycle can be enabled as needed.
At the start of each filter cycle, the pumps will run briefly to purge the plumbing to maintain good
water quality.
See Adjusting Filtration section within Spa Controls for more information.
