Replaces Atwood Hydro Flame
31501 and Suburban 520820
The FAN 50 Plus Pins is
designed to replace the new Suburban® and Atwood® / HydroFlame® Fan
Control boards as well as maintain backward compatibility with the Fan 50
Plus, and UIB Fan Control boards which have been available since 1994.
This board can also be used to upgrade older furnaces to add the Fan
Control feature.
The basic purpose of a Fan Control Ignitor Board is to shut the fan motor
off if the board fails to sense a flame after
the third ignition try. Thus, battery drain is reduced and the needless
blowing of cold air is eliminated.
The FAN 50 Plus Pins , after
shutting the fan motor off, will wait for 1 hour and repeat the whole
sequence again before
permanent shut down.
For 12 VDC Furnaces ONLY!
The "Fan Control" feature MUST BE USED
for proper operation of this board.
