Three 2T sensor housings are included with each Liebert CRV. The DIP switches in these sensors
have been preset at the factory. It is recommended that you confirm that the DIP switches have been
set correctly using the below table. Any additional 2T sensor housings will need their dip switches set
per the below table. If the dip switches are not set correctly, the control will not operate properly.
