2. The

BACnet

Server in

iTM

sends the new PV to Management Point in

iTM

. The

BACnet

Server in

iTM

then starts a 10 minute timer.

3. If the value in Management Point is changed (i.e., the indoor unit accepted the new value and

sent back the new status to

iTM

), the Management Point in

iTM

sends the new value to the

BACnet

Server in

iTM

. The

BACnet

Server in

iTM

updates the PV and resets the 10 minute

timer.

4. If the value in Management Point is not changed (i.e., the indoor unit did not accept the new

value and did not update the status to

iTM

) nothing happens. When the 10 minute timer

expires, the

BACnet

Server in

iTM

resets to the previous PV.
