---or-- Message
The Current Water Temperature is "Unknown" (- - - or - -) while in Economy or Sleep Mode.
Between Filter Cycles, while in the Economy or Sleep Heating Modes, the Pump has not turned ON and the Last Water Temperature is not current. To read the Current Water Temperature, either Change to Standard Heating Mode or turn On the Heating Related Pump, and wait at least 2 Minutes.
--F, --C, or -- Message
The Actual Water Temperature is "Unknown" (- -).
Priming Mode has been exited and the Pump has not yet run for 1 or 2 Minutes (depending on Model) to Sample Actual Water Temperature. With the Heat Related Pump Running, wait at Least 2 Minutes for the Correct Actual Water Temperature to be displayed. This is normal operation.

Ecn or Ec Message
If the Ecn or Ec Message is Alternating with the Water Temperature on the Display, the Spa is Operating in the Economy Heating Mode. If the Ecn or Ec Message is ON Solid (Not Flashing) on the Display, the Spa is Operating in the Economy Heating Mode, but there is No current water temperature because the Spa is between Filter Cycles. Ecn or Ec is Alternating with Temp: The Spa is Operating in the "Economy" (Ecn or Ec) Heating Mode.
The Water Temperature is sampled Only during Programmed Filter Cycles. The Heater will only operate and Heat up to Set Temperature during the Filter Cycles. The Water Temperature will probably drop Below Set Temperature between Filter Cycles. Other Heating Modes are Standard, Standard in Economy, and Sleep Modes.
Ecn or Ec is ON Solid (Not Flashing): The Current Water Temperature is "Unknown" (- - - or - -) while in Economy or Sleep Mode. Between Filter Cycles, while in the Economy or Sleep Heating Modes, the Pump has not turned ON and the Last Water Temperature is not current. To read the Current Water Temperature, either Change to Standard Heating Mode or turn On the Heating Related Pump, and wait at least 2 Minutes.
ICE, IC, or FREEZE COND Message
A Potential Freeze Condition has been Detected, and "Ice" (ICE) in the System is being Prevented.
44°F (6.7°C) or Lower has been detected at the Lowest Temp Sensor, or the Aux Freeze Switch has closed, and All Pumps and Blower are activated. All Pumps and Blower are ON for at least 4 Minutes After Temp is 45°F (7.2°C) or Above at the Sensors, or when the Aux Freeze Switch Opens. This is an Operational Message, Not an Error Indication.
