Comprehensive Data Tables; Bacnet Network Objects; Bacnet Data Points - Enfinity Single Stage Compressor - Daikin MicroTech III Sales And Engineering Data Sheet

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 Enfinity
Compressor, and the SmartSource
and Enfinity Large Two Compressor models are highlighted
below in the following tables:
• Table 1 - Table 7: Enfinity 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; Enfinity
Large Two Compressor models CCH/CCW, LVC/LVW
(notes for all tables are shown at the end of Table 14)

Please note that anytime a command is written to a configuration property,
this information is stored in the unit controller's non-volatile memory. Writing
to non-volatile memory is an operation that has a finite limit. For this reason,
the number of writes made to BACnet objects linked to configuration
properties must be limited to avoid damage to the hardware.
The BACnet Configuration and
Occupancy Modes, and
sections provide supplemental configuration and temperature
setpoint operation details. The BACnet PICS for each WSHP
model is included at the end of the document. See
A: Protocol Implementation Conformance Statements (PICS).

Troubleshooting Guide, available on www.DaikinApplied.com,
