outdoor air intake duct installation
Mount the sensor in an outdoor air intake by drilling a ¼ inch hole within 8
inches of outside. Angle the hole towards the outside. Insert the temperature
sensor into the intake pipe until the sensor is at least 2 inches outside the
structure in the intake pipe. Seal the hole and secure the wire so it cannot
be accidentally pulled out.
