Display shows EC or ECO, spa heats less often and may feel cool

Safety first: No electrical work is required for this condition.

• Check mode: On the Sunrise Spas topside panel, navigate to the mode settings and verify whether the spa is in Standard, Economy, or Sleep mode.
• Change to Standard: If you want continuous heating, select Standard mode so the spa maintains set temperature at all times.
• Review schedule: Disable any programmed filter/heating schedules that limit heating to certain times if not desired.
