MicroTech® III Controllers for Open Choices™ Integration

For Daikin McQuay Water Source Heat Pump Products

Daikin McQuay SmartSource

™

and Ennity

™

water source heat pumps are equipped with factory-mounted MicroTech® III unit controls for optimized performance. Optional Open Choices communication modules provide easy integration with your building automation system using BACnet® or

LonWorks

networks.

Open Choices Advantages

• Easy, low cost integration into building automation systems without expensive gateway panels

• Comprehensive unit control and status information available with either BACnet or LonWorks. See typical points list on reverse

• Easy conguration and simplied addressing to reduce

installation time

Advanced Control Strategies and Troubleshooting for Optimized Performance

The MicroTech III unit controller with a LonWorks or BACnet communication module coordinates the following operations for advanced control and easy troubleshooting.

• Enable heating and cooling to maintain setpoint

• Monitor discharge air temperature

• Space temperature control

• Monitor leaving water temperature

• Enable fan cycling and compressor operation

• Relay status of all vital unit functions

• Monitor all equipment protection controls

• On-board status LEDs aid in diagnostics by indicating

the water source heat pump communication conditions

• Remotely reset alarms and adjust setpoints

Comprehensive Data Available

The MicroTech III unit controller provides water source heat

pump unit status information and noties your BAS of alarm

conditions, regardless of the communication protocol.

• BACnet MS/TP

• LonTaLk SCC (FTT-10A) designed in accordance

with the LonM a rk® Space Comfort Control (SCC)

LonMark 3.4 certied with the appropriate

communications module for LonWorks® networks.

Open Choices Feature Components

The BACnet or LonWorks communication module can be

factory or eld installed and is tested with all logic required

to monitor and control the water source heat pump unit. The MicroTech III controller with communication module

includes unit-mounted return air, discharge air and leaving water temperature sensors. Options include a tenant setpoint adjustment knob and tenant override button and the ability to substitute the return air sensor with wall-mounted room sensor.

2. Conguration proper ties reside in EEPRO M that

has a write cycle limit of approximately 10000 writes. Do not unnecessarily write to conguration properties as this can limit the life of the device.
