three-position rotary switch

controls the fan speed.
Turn the switch clockwise to positions 1, 2, or 3 to set
the fan speeds to low, medium or high respectively.
The roof vent controls include an on/off switch and
a thermostatically controlled fan speed switch. The
12volt DC fan provides proper ventilation, comfortable
temperature control and adequate air flow. It is also used

operating the fan produces maximum air flow. Opening
windows farthest away from the fan will provide the
best air exchange. Open windows sufficiently to allow
proper air circulation.
