LCD MESSAGES
Ozone (Flashing) - The ozone generator’s
UV lamp has burned out. Contact your
Caldera Dealer for a replacement.
Economy - “ECON” flashing alternately with the current spa water temperature (the spa is in the economy mode). “ECON” flashing alternately with current water temperature and “COOL” (the spa is in economy mode and water temperature is more than 200F cooler than set water temperature).
Overheat Protection (spa is deactivated) - If a malfunction occurs and spa water tem- perature reaches 1120F, the system will com- pletely shut down. In such a condition, DO NOT ENTER THE WATER. Turn off all power to the spa and contact your Caldera dealer.
Freeze Protection - If a potential freeze condition is detected, both Hydro jet pumps are automatically activated. This is a normal spa function; no corrective action is neces- sary. Freeze protection is enabled regardless of the spa’s operating status.
Irregular Voltage - Irregular voltage to the control module or malfunction of the ozone unit is detected. To test for ozone malfunction, unplug ozone unit. The ozone plug is located on the right hand side of the control module. Reset the system at the breaker panel. If “ILOC” disappears after resetting, the ozone unit has malfunctioned. If “ILOC” reappears after resetting, contact your Caldera dealer.

CALDERA PURE WATER OZONE SYSTEM
The optional Ozone Generator operates during filter cycles to disburse ozone into the spa through an ozone jet located in the footwell of the spa. Water flow from the ozone system should be checked periodically; small bub- bles should be seen rising from the ozone jet.
When the ozone generator’s UV lamp burns out, “O3” flashes on the LCD alternately with the water tempera- ture during filter cycles.
Flow switch (constantly displayed) - An air lock may have occurred (refer to “PRIMING THE PUMP(S)” on page 18 for priming instructions), or a flow switch has malfunctioned. Contact your Caldera dealer.
Flow Switch (flashing) - The flow switch is not detecting an adequate amount of water flow. Make sure the spa is filled to 1 inch above the highest jet. The spa will continue to operate, but the heater will not activate. Contact your Caldera dealer.
Temperature Set Back - If the spa water temperature is more than 200F cooler than the temperature set point, the heater will automatically activate to provide freeze pro- tection. This is a normal spa function; no cor- rective action is necessary.
