DESCRIPTION
The XCHANGER model X2D is a dual fan mechanical ventilator capable of exhausting inside air, providing fresh outside air or provid-
ing a balanced air exchange. The fans can be independently switched on or off or be easily reversed to provide fresh outside air or
exhaust inside air. The XCHANGER X2D includes a dehumidistat control which operates the fan(s) based on the relative humidity
sensed by the control inside the home. The dehumidistat control includes an “On” setting that will operate the fan(s) continuously or
the switch can be turned “Off” so the fan(s) do not operate during undesired seasons. The XCHANGER can also be operated by a
standard plug-in wall timer. Tjernlund’s optional SCP speed control kit is also available if desired.
