Safety first: No electrical disassembly is needed for this setting change.

Switch out of Sleep mode:

• Enter mode menu: Use the topside control buttons (often TEMP and LIGHT or JETS) to cycle through modes.
• Select Standard/Ready: Choose STD or READY mode so the spa maintains temperature around the clock.
• Confirm operation: Verify that the heater icon appears periodically and that the water temperature rises toward the set point.
