Beschreibung
Zusammenfassung:	A system for verifying the operability of one or more HVAC devices (12,14,16,18,20,22) in a communication network (24) includes a network control device (10) that sends a particular type of message to the HVAC devices. Each HVAC device receiving the message will initiate a clearly visible display (32) on the HVAC device if the message is appropriately processed within the receiving HVAC device. Each HVAC device may be visually checked to confirm that it is in fact responding to the message from the network control device.
