Sequence of Operation • Supported Controllers: FHP560 and FHP583. • Depending on the options selected, an Input Expansion Module may be required to support additional inputs. • A detailed points list (included in the BACview Manual) should be consulted for specific points and values. Control Source (Run Conditions) The heat pump unit may have external or internal control sources to initiate heating or cooling operation.
*Subject to availability of IN-1 (input 1) The LON Works protocol is supported with an option card (Figure 11). The unit is enabled by the occupancy command, which is provided by the BAS. Correct hardware setup of the FHP-560 and 583 is required (BAUD rate and Communication Selection). Manual On: Places the Heat Pump in manual run mode; the unit will operate until the setpoint is satisfied.
Unit Mode The Unit Mode is used to configure the heat pump per its specific design configuration and application. A unit mode may be selected from the following: • Cooling Only • Auxiliary Heating (Cooling Only + Aux Heat) • Heat Pump • Heat Pump with Aux Heat • Heat Pump with Hot Gas Re-Heat • Cooling Only with Hot Gas Re-Heat Cooling Only The unit is configured for mechanical cooling only and the reversing valve and plumbing are not installed.
Re-Heat cannot be installed in the field. Consult the humidity control section of this document for detailed operation with HGRH. Cooling Only with Hot Gas Re-Heat The unit is configured for cooling only with active humidity control. Please see Heat Pump with Hot Gas Re-Heat for additional details. Temperature Sensor Selection A temperature measurement is required by the DDC control software for proper unit operation and control of space temperature.
The following applies to the Sensors: • Only one temperature source value will be used by the control software. A RS sensor may be installed to provide temperature feedback to the occupant even if a BAS or remote sensor is installed. • A zone remote sensor may not be installed with a hardwire CO2 sensor. Option configuration must be specified and adapted as required by the application. The software will lock out the remote temperature sensor if a hardwired CO2 option is selected.
Set-points Management All set-points are adjustable via the network or with the BACview terminal. Adjustment Limits is used to limit the allowed set-point changes via the wall sensor. For a given set-point the adjustment amount is limited to ± 3 °F; this limits the upper and lower set-point adjustment allowed by the user. Zone Control Status Information is available via the BAS: • Run Status – indicates the current commanded status of the unit, (on/off).
• +10 degrees below heating set-point The high and low zone temperature alarm trip points may be customized via the Alarm Configuration Screen utilizing the BACview terminal. The remote zone sensor hardware is validated if appropriately configured/installed. Fan Mode The Fan Mode option is used to select the type of fan hardware being used with the unit. Fan hardware is application specific and it will determine the behavior for the specific application for which it is being applied.
The Fan will operate when the cooling or heating PID value is greater than 10% for zone control applications, if it is set to cycle with the compressors. For Discharge Air Control (DAC) applications, the fan input percent is acquired from the PID static pressure control logic. DAC fan operation will run only during occupancy and for the unit being configured for discharge air control. The fan may be configured for continuous operation during occupancy or for operation during compressor operation.
pressurization of the space. The speed of the fan during a smoke event is user configurable for VFD enabled units (defaults to 100%). Fan History Statistics The controller will collect fan history statistics and sum the total number of fan start events that occurred in the proceeding 1 hour period. The fan history may be reset by the user. Fan history reset may be performed locally at the unit with a BACview terminal.
Filter Status (DFS) The FHP-560/583 controller has the option of providing a filter alarm for indicating that the filter needs servicing. The filter-status service option may be implemented with hardware or with fan run time. For dedicated functionality (without expansion module), the filter switch hardware is connected directly to IN-5 with a contact closure indicating a service event and the equipment integrator must configure the dedicated filter switch option.
Differential Pressure Switch (DPS) The differential pressure switch is applied to a unit for which the flow of water through the heat exchange must be confirmed prior to the unit operating. For dedicated functionality, the differential pressure switch hardware is connected directly to IN-5 with a contact closure indicating a service event, and the DPS option must be configured by the equipment integrator.
Smoke Detector Status (SDS) The unit may be setup to receive a smoke event via a contact closure. The smoke detector input is wired to the expansion module. Consult the wiring diagram for specific wiring port location. The response to a smoke event must be determined by safety regulations and jurisdiction of the local governing body. The smoke detector response must be enabled and setup by the system integrator and safety personnel.
• The valve start command is delayed by a valve delay counter; a delay of 60 seconds is used. • The equipment integrator must select the proper expansion module option and valve end switch for the unit configuration. • The condenser water valve is opened by starting the compressor. Heating & Cooling Operation The controller will measure the zone temperature and stage the compressor(s) to maintain its set-point.
Dedicated Outside Air When in cooling mode, if the unit is equipped with modulating hot gas re-heat valve, it will be enabled and modulated to maintain supply air temperature set point, factory default is 55 °F (adj.) +/- 2°F. The cooling stages are reset with outside air temperature (OAT) as it changes as follows: Mechanical Heating 45 °F 60 °F (adj.) Mechanical Cooling Full Load OAT > 75 °F (adj.
Discharge Air Temperature (DAT) Sensor The DAT sensor is typically factory installed at the inlet of the blower housing and connected to IN-6 of the FHP-560/583 controller. For parallel coil applications it is best to locate a duct mounted sensor in the supply air stream since supply air stratification can occur during 1st stage operation. Supply duct sensor placement provides a better measurement of the discharge air temperature due to the mixing process.
