The FHP560 Multi-Protocol Heat Pump controller is used in most configure-to-order applications requiring integration of Direct Digital Control (DDC) systems. The controller is BACnet™ native but is flexible enough to integrate into existing Building Automation Systems (BAS) via a choice of the most widely used protocols.
The FHP560 is packaged with a highly sophisticated yet easily configurable software (version 7.05.03) that suits the different heat pump applications. User parameters and options relating to the physical build of the corresponding heat pump unit (e.g. number of compressors, reversing valve, reheat coil, etc) are usually programmed at the factory to facilitate a seamless integration in the field. However, commissioning of the controller in the field is required to ensure the setup exactly matches the requirements of the jobsite. User settings of the factory standard software, such as the time and test and balance set points, are usually set up during the installation and commissioning process.
When properly connected to a Bosch Water Source Heat Pump (WSHP), the FHP560 controller works in tandem with the onboard Unit Protection Module (UPM) to protect the unit compressor from faults such as high/low pressure, high condensate, freeze evaporator/condenser coils, and brown-outs. The controller monitors the alarm contacts of the UPM board, then decodes and broadcasts any fault conditions that may arise over a network if one is available.
The controller also works with multi-functional ZS room sensors that, depending on model, are capable of reading not only the zone temperature, but also CO₂ and relative humidity levels. When wired correctly, the controller commands the heat pump unit to operate in heating or cooling mode, and can also provide commands for other options such as hot gas reheat to manage relative humidity while cooling. The operating parameters of the unit may be communicated to a BAS over the DDC network if available.
