SS=0 SS=S LS=O LS=S = Multiple causes open sensors, bad connection to panel, improper voltage, etc. = "Watchdog" (spa is deactivated) A problem has been detectedīJ2P = Pump/Blower purge - normal conditionįP = Freeze protect-temp under acceptable condition Pnl = Communication between PCB and panel interrupted HOT = PCB temperature above acceptable limit - air blower on Hold = Panel buttons pressed to many times to quickly ILOC = Interlock failure - possible pump or ozone spikeįLO = Pressure switch malfunction or Flow switch malfunction (system specific) Low speed pump (and air blower if so equipped) will activate to assist in lowering temperature. OH = High temperature condition, has reached 110✯. Low speed pump and heater will activate until spa reaches 65✯. If water temperature drops 20✯ below set temperature, low speed pump and heater activates to bring temperature within 15º of set temperature. Switch closed while pump is deactivated.ĬOL = Cool condition. Check for clogged filter.įL2 = Pressure switch problem. Check for proper spa water level and ensure pump is primed. Heater is deactivated.įL1 = Water flow problem, inhibited or pressure switch malfunction. Sn1 = Nonfunctional high temperature sensor. Replace bulbįL = Flow/pressure switch stuck in closed position Sn3 = Open or shorted sensor ( heater disabled).įLO2 = Closed or shorted flow switch on system startupīLB (or 616) = ClearRay Ozone bulb service warning. Sn1 = Open sensor (heater is deactivated) or Shorted sensor (spa is deactivated). = "Watchdog" (spa is deactivated) A problem has been detected. PnL = Communication between the panel and circuit board is faulty. HOT = Circuit Board temperature has exceeded acceptable limit. Hold = Panel sensors have been pressed too many times in a short period of time. OH = Overheat Protection (Heater is deactivated, pumps low speed is activated).ĬOOL = Spa water is more than 20° F cooler than the temperature set point.įLO* = Flow Switch (heater is deactivated. Heater is deactivated.įLO = Pressure switch failure, switch openįLC = Pressure switch failure, switch closed SN = Non functional high temperature sensor. OH = Overheat 108° F, spa is deactivated. Th3/39 = On startup indicates water temperature less than 39° F. Th2/current temperature = On startup indicates temperature probe problem. Th1/39 = On startup indicates temperature probe problem.
SE = Spa operating in Standard-in-Economy Mode. (Displays when first powered up after refill). ILOC = Interlock failure - possible pump or ozone spike. Pr = When spa is first actuated, it will go into Priming Mode. (Displays on third occurrence of "dr" message). Heater is shut down, but other spa functions run normally.ĭr = Inadequate water detected in heater.ĭry = Inadequate water detected in heater. (Displays on the 5th occurrence of "HFL" message with 24 hours). HFL = Substantial difference between temperature sensors detected. If display shows only this message (blinking) spa is shut down. If alternating with temp, may be temporary condition. Sensor plugged into jack B is not working. Sensor plugged into jack A is not working. ICE = Potential freeze condition has been detected One sensor has detected 110✯.įlo = Improper flow or pressure switch malfunction Pd = Power supply, unit running on battery backup PSoH = Pressure switch open with high pump. PSoL = Pressure switch open with low pump. PSoC = Pressure switch open with circulating pump. Heater disabled but the spa is operational. Hi limit sensor is disconnected or shorted or the spa temperature is above 112° F. Do not use spa when temperature is flashing or the OH message is displayed. The low speed pump or circ pump will operate continuously until the temperature rises above 45° F. CoLd = Temperature in the spa heater housing is below 40° F.
