Display shows EC or ECO and spa heats less frequently than expected

Safety first: No internal work is required.

Steps to adjust EC/ECO:

• Check mode setting: Use the topside control to view the current heating mode. If set to Economy or Sleep, change to Standard or Ready mode for continuous temperature maintenance.
• Review filtration schedule: Adjust filtration times so that heating can occur more frequently if desired.
• Monitor temperature: After changing modes, allow several hours for the spa to reach and maintain the new set temperature.

When to call a technician: If the spa will not exit EC/ECO mode or the display is unresponsive, the topside control or control pack may need service.
