With this. ƒ The Indoor unit stores the latest setting in EEPROM which has the maximum writable number of 100. so that the highest priority value would be transferred to the indoor unit. ƒ Priority Array ƒ An object in the BACnet Interface has a priority array. Releasing BMS value by sending a NULL command will revert point to default settings stored in the gateway of 25oC (77oF). ƒ Do not change anything frequently and you will be ok. Keep below 19 average per day. so that you may have to make conversion program if BMS doesn’t support it natively.000 times. a BBMD is required and should register BACnet Interface as a Foreign Device. ƒ BACnet Interface should also be configured as a Foreign Device and set BBMD IP address and port No.Foreign Device ƒ When BACnet Interface is in a different subnet from BMS.

The BMS will get all available objects from the Daikin BACnet interface by reading the object list property in the Device object. Can the BACnet gateway be configured to report temperature values in oF? A. No limitations that I’m aware of. Q. individually applied? A. Q. Can the BACnet gateway be set up as a BACnet Broadcast Management Device (BBMD)? A. Q. What changes can be globally applied vs. however it can be setup as a foreign device to communicate directly with a BBMD on a different subnet. Unit by unit (or units in remote control group). and Instance Number for each point. Must mode changes be done unit by unit or can they be done globally? A. Allows for less potential for error as manual command which can require matching up Port Number.
