Display shows ECON or EC; spa heats only during filter cycles and may not reach set temperature quickly.

Safety first: No internal electrical work is required.

• Change mode: Use the Mode or Settings button on the topside to cycle from ECON/EC to STANDARD/ST or READY mode, depending on your model.
• Adjust filter cycles: Ensure filter cycles are set to run long enough for desired heating if you choose to remain in economy mode.
• Monitor temperature: After changing modes, allow several hours for the spa to reach the new set temperature.
