BACnet Support Advanced Application Controller (B-AAC), as defined in BACnet 135-2001 Annex L
Communication Ports Network Comm port: EIA-485 port for BACnet MS/TP, Modbus RTU, or N2 communications
(protocol and baud rate are DIP switch selectable);
Comm Option port: For connecting a LON Option Card;
Local Access port: For system start-up and troubleshooting (115.2 kbps);
Rnet port: For connecting Carrier communicating room sensors and Carrier’s touchscreen
user interface
Inputs 4 analog inputs: Dedicated to Relative Humidity, Indoor Air Quality, Supply Air Temperature, and
Leaving Condenser Water Temperature. AI’s have 10 bit A/D resolution.
4 binary inputs: Stage 1 Compressor Status, Condensate Overflow, Fire/Smoke Detector, and
Fan Status (optional)
Outputs 2 analog outputs: 1 dedicated to Outside Air Damper, and 1 configurable for either Auxiliary
Reheat or Waterside Economizer. AO’s have 10 bit D/A resolution.
8 binary outputs: Supply Fan
(low, medium, and high), Compressor Stage 1, Compressor Stage 2, Reversing Valve, Auxiliary
Heat/2-position Waterside Economizer, and Dehumidification. Relay contacts rated at 3A max @
24VAC, configured normally open

Real Time Clock Battery-backed real time clock keeps track of time in event of power failure
Battery 10-year Lithium CR2032 battery provides a minimum of 10,000 hours of trend data & time retention during power outages
Protection Incoming power and network connections are protected by non-replaceable internal solid-state polyswitches that reset themselves when the condition that causes a fault returns to normal. The power, network, input, and output connections are also protected against voltage transient and surge events.
Status Indicators LED status indicators for network communications, run status, error, power, and all digital outputs
Controller Addressing Rotary dip switches set BACnet MS/TP, Modbus, or N2 address of controller

Integrated Water Source Heat Pump Controller

Carrier’s WSHP Open controller is an integrated component of a Carrier water source heat pump. The WSHP Open controller continuously monitors and regulates water source heat pump operation with reliability and precision. This advanced controller features a sophisticated, factory-engineered control algorithm that provides optimum performance and energy efficiency. The WSHP Open controller also features plug-and-play connectivity to the Carrier i-Vu System. The Carrier i-Vu System combines state-of-the-art Carrier equipment, plug-and-play controllers, and the powerful, web-based i-Vu user interface to form a cohesive, intuitive, and fully-integrated BACnet® Building Automation System.

For added flexibility, the WSHP Open controller is capable of stand-alone operation. Or, it can be integrated with any Building Automation System utilizing the BACnet, Modbus, or N2 protocols.
