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.
Application Features
- Controls 2 stages of DX cooling to maintain space temperature setpoint
- Integrated 2-position or modulating waterside economizer for optimized mechanical cooling
- Controls modulating or 2-position outside air damper to meet ASHRAE 90.1 requirements
- Built-in advanced control routines for zone level humidity control or zone level demand control ventilation (ASHRAE 62)
- Supports auxiliary modulating reheat, 2-position hot water/steam reheat, or electric heat
- Independent fan speed and compressor staging ensures quiet operation and maximizes latent heat removal for increased occupant comfort
- Modulating fan speed and compressor staging ensures safe unit operation
Hardware Features
- Compatible with Aquazone™ horizontal and Puron® vertical water source heat pumps
- Integrates easily into any BAS using BACnet, Modbus, or N2 protocols
- On-board hardware clock, remote occupancy input, and support for SPT/thermistor sensors provide stand-alone operation
- Easy startup and commissioning using Carrier’s BACview Handheld Service Tool
System Benefits
- Integrated Carrier airside linkage algorithm for plug-and-play integration with the Carrier WSHP System
- Fully plug-and-play with the Carrier i-Vu System
- Supports demand limiting for maximum energy savings
- Compatible with i-Vu Tenant Billing for tracking tenants’ after-hours energy usage
Specifications
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. |
