MASTER SPA - LEGEND SERIES - CONTROLS
Timeouts refer to a preset length of time that a function is programmed to operate before shutting off
automatically. Certain conditions (filters or freeze) can cause a function to operate longer, while faults
can cause a function to operate for a shorter length of time. The system keeps track of timeouts
regardless of other conditions occurring.
In multi-button sequences, if buttons are pressed too quickly in sequence, they may not register.

Initial Start-up

information). The Priming mode will last for up to 4 minutes and then the spa will begin to heat and
maintain the water temperature in the Standard mode. You can exit Priming mode early by pressing
“Warm” or “cool”.
