Fault Code F06 - Return (inlet) temperature exceeds 230F

This display indicates that the return temperature of the boiler is excessive. If accompanied by the red FAULT light, the return sensor temperature 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 boiler is RESET.
If the red FAULT light is not illuminated, then the return 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.
