4.14 THERMOSTATICALLY CONTROLLED CEILING FAN
Your trailer may be equipped with a roof vent with
a reversible fan to provide a controlled air flow
through the vehicle. Use the vent fan in
conjunctions with an open window to provide a
flow of fresh air into the unit.
Use these controls:
1. In/Out:
This rocker switch controls the rotational
direction of the fan in the vent. Depress the
IN side of the switch for the fan to draw air
into the coach. Depress the OUT side for the
fan to blow air out. The fan must always
come to a complete stop before changing
directions.
2. ON/OFF Fan Speed:
This 4 position rotary switch controls the
power to the fan and the fan speed. Turn the
switch to its most counterclockwise position
to turn the fan off. Turn the switch to its first,
second or third clockwise detents (Position 1,
2 and 3 respectively) to set the fan speeds at
low, medium or high. The roof vent must be
open at least 3 inches or the internal safety
switch will prevent the fan from coming on.
3. Vent Height:
This knob controls the position of the vent
hood. Turn the knob clockwise to pull the
hood down and close it. Turn
counterclockwise to raise or open the hood.
4. Thermostat:
This rotary switch controls the set point for
the system thermostat. Turn the knob to the
desired position. Moving the pointer to the
red portion of the scale will increase the
temperature of the set point for the vent fan to
come on. To operate, the vent must be open
and fan switch turned to either in or out.
5. Remote Control switch (optional)
a. Turn the knob clockwise to open the roof
vent to the desired position. Turn
counterclockwise to close it.
b. Turn the knob clockwise to the desired
fan speed position.
