Electronic Control Configuration
Depending on the equipment options installed by the
recreational vehicle manufacturer, the appropriate dip
switches will need to be switched to the "ON" position.
See Fig. 29. Placing the switch in the "ON" position
selects that option.
Note: Dip switches are in the "OFF" position when shipped
from the factory except for models supplied with the heat strip
factory installed, (620515). For this model , the #1 dip switch
will be in the "ON" position. To gain access to the dip
switches, the shroud must be removed from the unit. Remove
the four mounting screws around the perimeter of the unit.
Next remove the electrical box cover. (The electrical box will
be on the curb side of the RV after installation.)
