|One flash every four seconds||Not an error. Indicates pilot is lit and main burner is off.||Gas valve is powered and waiting for the set point knob to be turned to a water temperature setting. If the set point knob is at desired setting, the thermostat is satisfied.|
|One flash every second||Not an error. Indicates main valve is open and main
burner is lit.
|Thermostat is calling for heat. Water heater operating normally and is in heat cycle.|
|Solid ON||Not an error. Indicates that the control is in shutdown mode.||Set point knob was recently turned to “OFF” position. Wait until LED goes out before attempting to relight.|
|Two flashes and three second
