External communications port

Units with a factory-provided DDC controller can include a

service module (see Figure 125) with an external

communications port when purchased. Both the operator

display and Rover service tool can be connected without

shutting off the unit through the external communications

port. Open the cover plate on the service module 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 handler without disruption to the

operating conditions of the unit. When servicing of the unit

is complete, close the cover plate on the service module to

eliminate any air leakage path.
