BACnet Network Objects
The following section contains relevant information needed
to integrate a MicroTech III WSHP into the BACnet network.
The data point differences between the Ennity
™
Single Stage
Compressor, and the SmartSource
®
Two Stage Compressor
and Ennity Large Two Compressor models are highlighted
below in the following tables:
• Table 1 - Table 7: Ennity Single Stage Compressor
models MHC/MHW, CCH/CCW, VFC/VFW, LVC/LVW,
VHC/VHF (notes for all tables are shown at the end of
Table 7)
• Table 8 - Table 14: SmartSource Single and Two Stage
Compressor models GSH/GSV, GTH/GTV, GCV; Ennity
Large Two Compressor models CCH/CCW, LVC/LVW
(notes for all tables are shown at the end of Table 14)
The Selected Parameters Information section describes Binary
Input Status and Binary Output Status settings in greater detail.
CAUTION
Please note that anytime a command is written to a conguration property,
this information is stored in the unit controller’s non-volatile memory. Writing
to non-volatile memory is an operation that has a nite limit. For this reason,
the number of writes made to BACnet objects linked to conguration
properties must be limited to avoid damage to the hardware.
The BACnet Conguration and Commissioning, Effective
Occupancy Modes, and Space Temperature Setpoint Methods
sections provide supplemental conguration and temperature
setpoint operation details. The BACnet PICS for each WSHP
model is included at the end of the document. See Appendix
A: Protocol Implementation Conformance Statements (PICS).
Refer to OM 1085 Software Downloading Procedures and
Troubleshooting Guide, available on www.DaikinApplied.com,
for software part number and compatibility details.

Description
ANALOG INPUTS
Local Space
Temperature Output
AI:1 R LocalSpaceTemp
0 to 158ºF
-17.77 to 70ºC
Default:
68ºF / 20ºC
N
The value of the hardwired space temperature sensor
installed either in the return air or the space. Writing to
Space Temp Input (AV18) does not affect Local Space
Temp (AI1) but does effect Effective Space Temp (AV22).
6
Leaving Water
Temperature
AI:2 R LWT
0 to 158°F
-17.77 to 70°C
Default:
32ºF / 0ºC
N Displays the leaving water temperature sensor value.
6
Entering Water
Temperature
AI:3 R EWT
0 to 158°F
-17.77 to 70°C
Default:
32ºF / 0ºC
N Displays the entering water temperature sensor value.
6
Discharge Air
Temperature
AI:4 R DischAirTemp
0 to 158°F
-17.77 to 70°C
Default:
32ºF / 0ºC
N Displays the discharge air temperature sensor value.
6
Local Setpoint
Adjust Output
AI:5 R LocalSetpt
55 to 95ºF
12.78 to 35ºC
Default:
32ºF / 0ºC
N
The reference setpoint used to determine the Effective
Heating/Cooling setpoints. It is the value of the local,
hardwired space temperature setpoint. It is only valid if
the unit controller JP5 conguration jumper is congured
for Long Range Setpoint Adjust and is enabled by
MSV14.

Compressor
#1 Suction
Temperature
AI:6 R SuctionTemp
1
0 to 158°F
-17.77 to 70°C
Default:
32ºF / 0ºC
N
The compressor #1 suction line temperature sensor
value.
6
Compressor
#2 Suction
Temperature
AI:7 R SuctionTemp
2
0 to 158°F
-17.77 to 70°C
Default:
32ºF / 0ºC
N
The compressor #2 suction line temperature sensor
value.
6
Brownout Voltage
Reading
AI:8 R Brownout
0 to 1023 counts
Default: 0
N
The Brownout Voltage Reading is compared to the
reference setpoint to determine if the brownout condition
exists.
