External Communications Port

On units that have been selected with the external communications port, both the operator display

and Rover service tool can be connected without shutting off the unit through the external

communications port. Remove the cover plate on the port and plug into the RJ-11 port for the

operator display or the RS 485 port for the Rover service tool. This enables continuous operation

of the Air Handling unit without disruption to the operating conditions of the unit. When servicing

of the unit is complete, replace the cover plate on the external port to eliminate the air leakage path.
