Spa frequently overheats on sunny days even with normal set temperature.

Operational adjustments:

• Reduce filtration time: Shorten filtration cycles in the control settings to reduce pump-generated heat.
• Lower set temperature: Temporarily reduce the set temperature a few degrees during hot weather.
• Vent cabinet: Ensure the equipment bay door is properly vented and not blocked. In extreme cases, add additional ventilation grills per Marquis guidelines.
• Use cover wisely: Partially open the cover during the hottest part of the day to allow excess heat to escape, ensuring safety barriers are in place.
