i-Vu® WSHP Water-to-Water Open Controller.

i-Vu® WSHP Water-to-Water Open Controller

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.

Application Features

  • Controls up to 4 stages of capacity (up to 3 compressor stages), to maintain the desired entering or leaving water temperature
  • Provides 5 operating modes for manual or automatic system changeover operation
  • Provides load water pump output control
  • Provides source water pump or 2-position isolation valve control
  • May be configured to reset the water temperature proportionally based upon OAT during cooling or heating modes
  • In cooling mode, the control has the capability to limit the OAT reset based upon the difference between a measured humidity value and a configured high RH setpoint limit
  • For larger installations, a total of up to 8 stages may be controlled as a singular heating or cooling source. One controller will operate as the master, coordinating others in the system

Hardware Features

  • Compatible with Aquazone™ water-to-water water source heat pumps with Puron® refrigerant
  • Integrates easily into any BAS using BACnet, Modbus, LonWorks or N2 protocols
  • On-board hardware clock, remote occupancy input, and support for communicating/thermistor sensors provide stand-alone operation
  • Easy startup and commissioning using i-Vu User Interfaces

System Benefits

  • Integrated Carrier Condenser Water Linkage algorithm for plug-and-play integration with the source water system when controlled by a Carrier water loop controller
  • Fully plug-and-play with the Carrier i-Vu Building Automation System
  • Supports demand limiting for maximum energy savings
