Fault Code F13 - Combustion Fan Speed Low

The fan is not running at the speed that the control has commanded it to run at. The fan speed had been more than 30% faster or slower than the commanded speed for more than 10 seconds. The red light will display. This code indicates a serious safety issue and the boiler will not restart until the cause is determined by a technician and he pushes the RESET button on the display. During this lockout fault, the pump will be on.
