The following applies when changes are made through 

the BACnet configuration menu: If a period “.” is 

entered as the first character then the name is set to 

“MTIIIUC_WSHP_0000000” and the zeros are set to the 

device instance.  If a space character is entered as the 

first character, then the Device Instance is automatically 

filled in at the first 0 (zero) character in the name.  For 

example: Assume the Instance has been changed to 

321.  If the name was previously “WSHP_0000300” and 

a space is entered at the name prompt, the new name 

automatically fills in as “WSHP_0000321”.  If a period is 

entered at the name prompt, the new name changes to 

“MTIIIUC_WSHP_0000321”.

MaxMasters

Device

W

Max_Master

1 to 127

Default: 127

Y

MaxMasters should be set to the highest address of a 

MS/TP master on the network segment.  The default value 

is 127 for maximum compatibility.  Setting this to the highest 

address of an MS/TP master device on the network reduces 

the MS/TP token traffic and decreases the response time 

of the unit controller.  MaxMasters can be set from the 

BAS or from the BACnet configuration menu. See 

BACnet 

Configuration and Commissioning

.

MS/TP Baud Rate

NA

NA

NA

9600, 19200,  

38400, 76800

Default: 38400

Y

Set the baud rate to match the speed of the BACnet 

network.  Speeds above 38400 should be avoided unless 

the network wiring has been tested and verified to meet 

the required speed.  The baud rate must be set using the 

BACnet configuration menu. See 

BACnet Configuration and 

Commissioning

.

1. Parameter is stored in FLASH/EEPROM (non-volatile memory) in either the communication module or in the unit controller.  If Non-volatile Memory = Y, then the 

value is saved through a power cycle.  Writes to this parameter must be limited. If Non-volatile Memory = N, the value is not saved through a power cycle.
2. R = Read Only, W = Writeable, C = Commandable
3. The values of the individual Occupancy Temperature Setpoints (AV1 to AV6) must be kept in ascending order as follows:

AV6 <= AV5 <= AV4 <= AV1 <= AV2 <= AV3
4. AV412 has an ObjectName of SystemMinInstance, the Present Value is writeable, and it has a default value of 3101000. During the commissioning process, the 

present value of AV412 is added to the MAC Address to determine the Device Instance Number. In order to change the value of AV412 on the BACnet communication 

module in the unconfigured state, the BAS must broadcast a new present value to AV412 using the BACnet service (BIBB – BACnet Interface Building Block) called 

“Unconfirmed COV” with a ProcessID value of 1. This prevents unauthorized unconfirmed writes, or changes, to AV412. Note that this change affects the AV412 

present value for every MicroTech III WSHP BACnet communication module on the trunk.
5. The auto-addressing feature was designed for units communicating to a 

Daikin Intelligent System (IS) Manager.  However, any BAS can configure a MicroTech 

III WSHP unit controller with BACnet communication module for auto-addressing.  AV412 can be set via the BAS using auto-addressing, but this feature is intended 

primarily for the IS controller. See the Daikin System Manager Operation Manual, OM 1254, and the MicroTech III BACnet MS/TP Communication Module Installation 

Manual, IM 928, both available on 

www.DaikinApplied.com

, for complete details on using auto-addressing with the IS controller.

6. Analog Null is a discrete temperature value of 621.806ºF/327.67ºC.  Its purpose is to indicate a sensor failure condition or when the unit controller is not using that 

temperature value.
7. After Receive Heartbeat is enabled, this variable reverts to the default (non-override) value if it is not refreshed often enough through a network command or if 

communication is disabled (i.e. BACnet device communication control = disable).
