The RELXTIME control panel lets you control the main functions of your hot tub, including filtration, heating, temperature, and bubbles.
FILTER
Press the FILTER button to start the filtration system. A red indicator light appears when the filter pump is running.
Press the button again to stop filtration.
After 168 hours of filtration and heating operation, the FC code will appear on the display. Replace or clean the filter cartridge as required, then press the FILTER button to restart the system and clear the filter reminder.
HEATER
Press the HEATER button to start heating. The red indicator light shows that the heating system is operating.
When the preset temperature is reached, the heating element stops automatically while the filter pump continues to circulate the water.
If the water temperature drops approximately 2°C (3.6°F) below the set temperature, the heating system automatically starts again.
TEMPERATURE
Press the TEMPERATURE button to set your desired water temperature.
Use the TEMP UP and TEMP DOWN buttons to increase or decrease the temperature. Press the TEMPERATURE button again to confirm your setting.
The temperature range is 68–104°F (20–40°C).
BUBBLE
Press the BUBBLE button to activate the air bubble jets.
Press the button again to stop the bubbles.
The bubble function automatically stops after approximately 20 minutes as a safety feature. To use it again, wait 10 minutes before restarting.
Freeze Protection Mode
Some RELXTIME models include FP (Freeze Protection) Mode.
In FP Mode, the filter pump runs continuously, and the heating function automatically turns on when the water temperature falls below 41°F (5°C) to help keep the water above 41°F (5°C).
Do not use FP Mode if the spa water is frozen or below 32°F (0°C).
