All P Series units with ComtfortLink controls have a port<br />
for interface with the Carrier Comfort Network ® (CCN) system.<br />
On TB3 there is a J11 jack which can be used for temporary<br />
connection to the CCN network or to computers equipped<br />
with CCN software like the <strong>Service</strong> Tool. Also on TB3 there<br />
are screw connections that can be used for more permanent<br />
CCN connections.<br />
