MicroTech III Controller with 

BACnet® Communication Module

For installation and operation information on MicroTech 

III unit controller and other ancillary components, see:

■ 

IM 928 - MicroTech III BACnet Communication 

Module

■ 

OM 931 - MicroTech III Unit Controller for Water 

Source Heat Pumps Operation and Maintenance 

Manual

■ 

IM 955 - MicroTech III Wall Sensor For use with 

Microtech III Unit Controller

Daikin water source heat pumps are available with 

Daikin BACnet MS/TP communication module that 

is designed to communicate over a BACnet MS/TP 

communications network to a building automation 

system (BAS). It can be factory or field-installed. 

The unit controller is programmed and tested with all the 

logic required to monitor and control the unit. An optional 

wall sensor may be used with the communication 

module to provide limited local control of the water 

source heat pump. The unit controller monitors water 

and air temperatures and passes information to the 

communication module. The module communicates with 

the BAS, to provide network control of the water source 

heat pump. 
The module makes operational data and commands 

available on a communications network using BACnet 

objects and properties:

■ 

The network cable is a shielded twisted-pair cable

■ 

Network communications run up to 76.8 Kbps

■ 

DIP switches on the controller enable the MS/TP 

MAC address to be set in the range 0-127

NOTICE

When installing a MicroTech III Horizontal unit size 007, 009 
or 012 which are provided with a factory-mounted BACnet 
communication module, it is suggested that the MAC address dip 
switches on the communication module be set prior to installing 
the unit in the ceiling. Access to the dip switches may be limited 
when the unit is installed. Reference IM 928 for addressing 
methods available.

■ 

Four green status LEDs on the communication 

module indicate communication activity on the 

MS/TP communication network and with the unit 

controller

Snap-in Communication Module

MicroTech III Unit Controller with BACnet MS/TP 

Communication Module orchestrates the following unit 

operations:

■ 

Enable heating and cooling to maintain setpoint 

based on a room sensor

■ 

Enable fan and compressor operation

■ 

Monitors all equipment protection controls

■ 

Monitors room and discharge air temperatures

■ 

Monitors leaving water temperature

■ 

Relays status of all vital unit functions

The MicroTech III unit controller with 

communication module includes:

■ 

Return Air Temperature sensor (RAT)(field-installed)

■ 

Discharge Air Temperature sensor (DAT)(field-

installed)

■ 

Leaving Water Temperature sensor (LWT) (factory 

installed)

Note:  

Refer to IM 956-X for details to install (RAT) & 

(DAT) sensors.

 CAUTION

When an optional wall-mounted room temperature sensor is 
connected to the unit controller, the Return Air Temperature (RAT) 
sensor must not be installed. A wall-mounted room temperature 
sensor and the return air temperature sensor must not be 
connected simultaneously or the unit will not operate properly.

The communication module provides access to setpoints 

for operational control

Available wall sensors include:

■ 

Room sensor with LED status and tenant override 

button

■ 

Room sensor with LED status, tenant override 

button, and ±3°F setpoint adjustment

■ 

Room sensor with LED status, tenant override 

button, 55° to 95°F setpoint adjustment
