Product Integrated Controller

Carrier’s Water-to-Water (W2W) Open controller is an integrated component of a Carrier water-to-water source heat pump. The W2W Open controller continuously monitors and regulates heat pump operation with reliability and precision. This advanced controller features a sophisticated, factory-engineered control program that provides optimum performance and energy efficiency. For added flexibility, the W2W Open controller is capable of stand-alone operation. It can also be integrated with any Building Automation System using the BACnet®, Modbus®, LonWorks®*, or N2 protocol.

*Requires LON Option Card (p/n LON-OC)
