Step 7. Connect the heater. Connect the black hot wire to P3, white neutral to P4, and green ground to P5.
Step 8. Plug the heater sensor cable into P1.
Step 9. Plug the LED spa light into P33.
Step 10. Plug in the Gecko IN.YJ 3 Keypad into P22.
Step 11. Connect the incoming 230 volt power wires. Connect the white neutral wire to N, black hot wire to L1, and green ground wire to the green arrow on the terminal block.
For 230-volt operation, remove the brown jumper wire from L2 and P21.
Connect the second hot leg (Red Wire) to L2. The heater and jet pumps will run at 230 volts.
Step 12. After filling the spa, turn on the power. The display sequence at every startup will be lamp test, software number, software revision, and low-level selected. The display will show three dashes during flow verification. If the flow is sufficient, the temperature of the water is displayed on the keypad screen.
Now let’s program the breaker settings. Press and hold the light key (for about 20 seconds) until you reach the breaker settings menu. The filter cycle duration menu will come up first. Keep holding the light key down until you reach the breaker settings menu which will appear as b.24.
The values displayed by the system correspond to 80% of the maximum amperage capacity of the GFCI. Press and hold the Up/Down key to choose the desired value. For example: If you are using a 15A breaker, select b.12. If you are using a 20A breaker, select b.16. If you are using a 50A breaker, select b.40. Press the light key to set the breaker rating.
Step 13. Program the low-level configurations. Press and hold the Pump 1 button for 30 seconds. Press and hold the Up/Down key to select the new low-level configuration. Select L8 for spas with a 2 speed jet pump and a 1 speed jet pump. Select L10 for spas with an added circulation pump. Press the Light key to confirm the low-level configuration.
Step 14. To program the filter cycle duration and number of cycles in a 24-hour period, press and hold the light button down for 5 seconds until you see the letter d. Use the up and down keys to select the duration of the filter cycles in hours.
Press the light key again to select the number of filter cycles per day.
Press the light key again to choose C (Celsius) or F (Fahrenheit). Press the light key to return to the main menu.
Step 15. Test the LED spa light. The light icon will turn red when you press the light key. Tip: If the LED light fails to come on, power off the spa and turn the bulb around in the harness. The LED light will only work in one position.
HL = High Limit. If you see HL on the screen it means your spa is in High Limit Trip or Protection Mode. The system has shut the heater down because the temperature at the heater has reached 119°F (48°C). Do not enter the water! Remove the spa cover and allow the water to cool down, then shut power off and power your spa up again to reset the system.
