  • Page 5: Introduction

    Introduction What is the WSHP Open controller? The Water Source Heat Pump (WSHP) controller is available as an integrated component of a Carrier packaged unit. Its internal application programming provides optimum performance and energy efficiency. WSHP Open enables the unit to run in 100% stand-alone control mode or it can communicate to the Building Automation System (BAS).
  • Page 6 Introduction CAUTION If there is a jumper on the Format pins and power is cycled to the controller, all Modbus, N2, and LonWorks points will be lost. WSHP Open v3...

  • Page 7: Safety Considerations

    • Do not contaminate the printed circuit board with fingerprints, moisture, or any foreign material. • Do not touch components or leads. • Handle the board by its edges. • Isolate from high voltage or electrostatic discharge. • Ensure that you are properly grounded. WSHP Open v3...
