• Check mode: On the RivieraPool control panel, cycle through modes (e.g., Standard, Economy, Sleep) using the Mode or Temp button combination. Select Standard mode for continuous temperature maintenance.
• Adjust filter cycles: Ensure filter cycles are set to appropriate durations so that heating can occur during those times.
• Monitor temperature: After changing to Standard mode, allow several hours for the spa to reach and maintain the set temperature.
