MicroTech III Controller with Communication Modules Features
The MicroTech III Controller with LonWorks or BACnet
Communication Module orchestrates the following unit
operations:
Enable heating and cooling to maintain space
temperature setpoint based on a room sensor setting
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
An amber, on-board status LED indicates the status of the
MicroTech III LonWorks or BACnet module.
The MicroTech III Controller Includes:
A unit-mounted return air sensor
A unit-mounted discharge air sensor
A entering water temperature sensor
A leaving water temperature sensor
The communication modules provide network access to
setpoints for operational control
Available Wall Sensors Include:
Room sensor
Room sensor with LED status and tenant override
button
Temperature sensor with LED status, timed-override
button, and ±3°F setpoint adjustment
Room sensor with LED status, timed-override
button, 55° to 90°F setpoint adjustment

BACnet Communication Module
EachEnnityLargeVerticalWaterSourceHeatPumpcan
be equipped with a LonWorks or BACnet communication
module. The LonWorksmoduleisLonMark3.4certied
and designed to communicate over a LonWorks communica-
tions network to a Building Automation System (BAS). The
BACnet module is designed to communicate over a BACnet
MS/TP communications network to a building automation
system. Both controllers are microprocessor-based and can be
factoryoreld-installed.
The control modules are programmed and tested with all
the logic required to monitor and control the unit. Optional
wall sensors may be used with the communication modules to
provide limited local control of the Horizontal Water Source
Heat Pump. The MicroTech III 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.
MicroTech III LonWorks Communication Module
The LonWorks communication module is designed for
units that are integrated into a LonWorks communication
network for centralized scheduling and management of mul-
tiple heat pumps.
MicroTech III BACnet Communication Module
Designed to be linked with a centralized building auto-
mation system (BAS) through a BACnet communications net-
work for centralized scheduling and management of multiple
heat pumps.
