PROBLEM (displayed on the digital control) CAUSEWHAT TO DO
CODE : FLO
  • The water flow inside the heat pump is insufficient
  • There is no water circulation inside the heat pump
  • The flow switch is defective
  • Make sure the circulating pump works;
  • Make sure the bypass valves are properly positioned;
  • Check the skimmer (no obstruction);
  • Check the water pressure gauge of the heat pump, it should read between 10 and 15 psi.
  • CODE : FL3
  • The heat pump flow switch has cut off three (3) times in the same hour for one of the reason above (code FLO)
  • The heat pump will not re-start after one of the protection devices shuts it down for the third time in the same hour;
  • Close the circuit breaker to reset the heat pump.
  • CODE : FS
  • The heat pump is in de-icing mode
  • Wait until the end of the de-icing cycle. The heat pump will restart automatically
  • CODE : LP
  • Ventilation on the evaporator is insufficient
  • The fan does not work
  • Refrigerant leak
  • The outside temperature is too low
  • Check that the evaporator is not obstructed by pollen, grass, leaves; see the user’s manual for safety and maintenance tips
  • Be sure there is enough free space around the heat pump (see the Installation Guide)
  • Check that the fan is powered ON
  • CODE : LP3
  • The heat pump low pressure switch has cut off three (3) times in the same hour for one of the reasons above (code LP).
  • The heat pump will not re-start after one of the protection devices shuts it down for the third time in the same hour
  • Close the circuit breaker to reset the heat pump
  • CODE : HP
  • The water flow inside the heat pump is insufficient
  • The bypass valves are in the wrong position
  • The water exit is blocked
  • There is an obstruction in the refrigeration circuit (piping blocked)
  • Check whether there is adequate water circulation inside
  • Check that the bypass valves are properly positioned
  • Check if there is an object obstructing the water hose
  • CODE : HP3
  • The heat pump high pressure switch has cut off three (3) times in the same hour for one of the reasons above
  • The heat pump will not re-start after one of the protection devices shuts it down for the third time in the same hour
  • Close the circuit breaker to reset the heat pump
  • CODE : SPI
  • The digital control is defective
  • Close the breaker switch and re-open it. If the problem is not resolved, the digital control will have to be changed. In this case, call your dealer.
