8.1.2 Fan
Operating power is provided by means of a separate 120 VAC connector (white/black/green).
Control of the fan is provided via a four lead connector. This connector feeds a PWMcontrol
signal (black wire) from the controller and provides a tachometer signal (white wire) back from the
fan. Unplugging the control connector will cause the fan to go to high speed and trigger a
"Blocked Vent Error"within 6 seconds if the boiler is operating.
