The Astrel Easy heaters are available in several versions, depending on the power, the type of flow detection and the sensor model installed on it. All references start with "PFEAR" and end with "00000" or "00001" (the last digit is not important). The three digits after the letters PFEAR provide the essential information on the heater configuration.

If the control system thinks that there is not enough water flowing through the heater to heat the spa safely, it will shut down power to the heater, and you'll most likely see an error message on the display screen. Different systems use different messages, but some common ones are FLO, FL, LF, dr, drY, PS, FL1, FL2 or Err1, depending on the model of the control system installed.
