Functional Description
Messaging
The TNS HAN software is capable of sending 59 bytes of text to either the IHD or
the thermostat. The number of bytes a HAN device will receive, however, may
vary. The TNS operator has the option of specifying a display time duration,
message importance, and/or requesting confirmation for each message. The
message will appear in the HAN device display until the display time elapses, the
message is cancelled, or a new message is sent.
