Display shows SLP or SLEEP, spa temperature drops between cycles, heat only during programmed times.

Note: SLP is a user mode, not a fault.

• Switch to standard mode: Use the mode selection procedure (often pressing TEMP then LIGHT or JETS) to change from SLP to STD/READY.
• Review manual: Confirm how Saratoga Spas defines SLEEP vs ECON vs STANDARD modes for your specific control system.
