i-Vu® Open WSHP Controller
Product Integrated 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.
