Fault Code F05 - SUPPLY TEMP HIGH

This display indicates that the supply temperature of the boiler is excessive. If accompanied by the red FAULT light and LOCKOUT flashing on the display, this code indicates that the temperature on the supply sensor has exceeded 230F and a serious safety issue exists. The boiler will not restart until the cause of excessive temperature is repaired by a technician and the RESET button is pushed on the display. If the FAULT light is not illuminated and this message is displayed, then the supply temperature of the boiler is at or above 210F. The message will clear automatically when the temperature drops below 194F. During the time that this message or lockout fault is displayed, the pump will be on as indicated on the second line.
