F06 Fault Code: Return Temperature High

Postby HTP » Wed May 30, 2012 1:14 pm

This display indicates that the return temperature of the boiler is excessive. If accompanied by the red FAULT light and LOCKOUT flashing on the display, the return sensor temperature has exceeded 230oF 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 210oF. The message will clear automatically when the temperature drops below 194o F. During the time that this message or lockout fault is displayed, the pump will be on as indicated on the second line.
