1. This MS/TP Bus object is readable and only writable if the corresponding override is set. (For
example, Room Temp has a corresponding override object of Room Temp Override. This
corresponding override object needs to be set to 1 = Override to be able to write Room Temp to a
different value.)
2. This MS/TP Bus object is readable and writable.
3. This MS/TP Bus object may automatically release after 10 minutes with no BACnet traffic.
4. This MS/TP Bus object is readable and only writable when out of service.
5. This BI object type status is available even if the configuration is set to None.
6. This MS/TP Bus object requires that Frost Protection be set to 1 = On.
7. If one setpoint of a pair of heating and cooling setpoints (for example, Occupied Heat Setpoint and
Occupied Cool Setpoint) is overridden, the other setpoint of the pair may be automatically adjusted
by the thermostat controller to maintain the minimum deadband between the two setpoints.
8. The address range actually displays from 0 to 254. Only choose an address within the 4 to 127
range.
9. The designation aaa is the address of the device (from 004 to 127) on the MS/TP network.
