The Zone Controller The Zone control board also known as DDC The controller is programmed in the factory and shown in figure 1 is used in most with software versions that suit the different configure to order applications. applications FHP offers. User settings such It is BACnet® native which makes it flexible as the time and test and balance set points and easy to integrate into existing Building shall be set up during the installation and Automation commissioning process at the job site.
Specifications Power: 24VAC ± 10%, 50-60Hz, 20VA power consumption (Single Class II 70VA or 100VA option available) Physical: Rugged plastic housing protects circuitry. Environmental Operating Range: 40° to 130°F (-17.8° to 54.4°C); 10 to 90% relative humidity, non-condensing Digital Outputs: Five digital outputs relay contacts rated at 1A resistive @ 24VAC; normally open. configured as dry contact, Universal Inputs: 8 inputs.
Controller Components LED Indicators The DDC controller is equipped with three bank sets of LED that help the user diagnose problems and or identify normal operation. The first bank is located in the upper left Figure 2 - Network LEDs hand corner as shown in the figure 2. They flash repeatedly when the controller is communicating with the network and usually service support refers to them as Rx and Tx. The second bank is located on the upper right hand corner of the controller as shown in figure 3.
Figure 4 – Digital Output LEDs The Third Bank of LEDs are located on the bottom right corner of the controller as shown on figure 4 (right) and their purpose is to show the status of individual Digital Outputs (DO) as they are energized DIP and Rotary Switches Figure 5 – Controller Address Rotary DIP switch Two sets of switches can be found on the controllers, they must be set properly to IMPORTANT: allow correct operation of the unit.

Figure 8 - LonTalk® DIP Settings Jumpers and settings Controllers come equipped with a series of jumpers which allow different types of inputs to be terminated in a particular point.
LonWorks® card option LonWorks® is a network platform that allows any facility or to integrate sub-systems using a common system architecture and infrastructure. This platform provides fully open operability of the components within a system or sub-system, this enables the facility owner to utilize different vendors and still have the capability of integrating their system into one single server or front end. The LON card option is available for both controllers 641-224 and 641-242.
Water to Air Operation General Description The Heat Pump Factory mounted I/O Zone 560 or 583 DDC Controllers are factory configured with the Water to Air application program and factory installed in the unit to be job site configureable to run. The unit will operate in a 100% stand-alone control mode or connect to a Building Automation System (BAS) using open protocols BACnet® (ARCNET and MS/TP), Modbus RTU, N2 or LonWorks® (additional network interface board required for LonWorks® option).

Sequence of Operation Run Conditions: The unit will run according to a user definable time schedule, dry contact (physical digital input number 1), manual ON command from BACview control interface, timed local override from Zone temperature sensor or via third party front end start command (software point). When commanded to run the unit will operate in the following modes: Occupied Mode: The unit will maintain A 74°F (adj.) Cooling setpoint A 70°F (adj.
Zone Temperature The occupant will be able to see the zone temperature on the sensor LCD display in addition the user will be able to see other parameters that have been configured in the controller such as alarm status, alarm codes, Inputs and outputs status among others. NOTE: These codes and values vary from version to version for additional information on what is available on the RS-Pro sensor please check its commissioning BACview manual in our web site www.fhp-mfg.com.
Freeze Protection: The unit shall shut down and generate an alarm upon receiving a freezestat status. Fan: Constant Volume In the occupied mode, the fan shall run continuously or cycle with the compressor(s) depending on fan mode settings. In the unoccupied mode, fan cycles as required for unoccupied heating and cooling setpoints while in night setback.
Modulating Re-Heat Valve: This valve is an analog device and has the capability to modulate the amount of hot gas that is allowed through the re-heat coil, thus allowing control of the discharge air temperature to a user defined setpoint.
The heating will be enabled whenever: The fan output is on. AND the reversing valve is in heat mode (de-energized). The cooling will be enabled whenever: The fan output is on. AND the reversing valve is in cool mode (energized). Reversing valve: The reversing valve is energized on a call for cooling and will remain energized until a call for heating.
The controller will only allow supplemental heating if the unit is configured to allow this operation, units equipped with hot gas re heat valves or damper control enable will not have supplemental electric heat functionality. Discharge Air Temperature: The controller will monitor the discharge air temperature to be located at discharge side of coil. If the supplemental heating is installed then sensor will be in the discharge side of heating coil.
Single Outside Air Temperature (OAT) Reset: OAT> OAT Reset °F (adj.): Controller will initiate cooling call to run compressors and modulate Re-heat Valve only when the outside air temperature is greater than 55°F (Factory Default) OAT< OAT Reset °F (adj.): Controller will initiate a call for heating. Straight cool units will run their fan continuously or if the unit is equipped with a Variable Frequency Drive (VFD) it will command the drive to maintain its static pressure setpoint.
Controller will command the unit to run full mechanical cooling operation (on units with more than two compressors please check with factory), the valve will be set for cooling operation and both first and second compressors will be commanded on, the fan will run continuously or if the unit is equipped with a Variable Frequency Drive (VFD) it will command the drive to maintain its static pressure setpoint and the re-heat valve will be modulated to maintain a 65°F (Factory Default (adj.

Sequence of Operation Run Conditions: The unit will run according to a user definable time schedule, dry contact (physical digital input number 1), manual ON command from BACview control interface or via third party front end start command (BV software point). When commanded to run the unit will operate in the following modes: Occupied Mode: The unit will maintain A 54°F (12°C) adj. Cooling setpoint A 105°F (40 °C) adj.
Auto Cool: Chageover Temperature > Changeover Setpoint + Change over dead Band Auto Heat: Chageover Temperature < Changeover Setpoint - Change over dead Band When using the changeover feature the system will require an air temperature sensor (10KΩ @ 77°F (25°C) Thermistor) typically located in the controlled zone.
Lead - Lag Compressor operation NOTE: This feature is only available on two stage systems. The unit will alternate the compressors by using Lead Lag control algorithm; the rotation method is user definable and can be set during the commissioning process as follows: Monthly Daily Time of Day By default the unit will change its lead compressor if the one acting as lead fails.
Load Water (Entering) Temperature: The controller will monitor the entering load water temperature which is located at entering side of coil. Alarms will be provided as follows: Load High Temp: If the water temperature at the entering load side is greater than the cooling setpoint plus a user definable amount (adj.), the factory default for this amount is 10°F. Load Low Temp: If the water temperature at the entering load side is less than the heating setpoint minus a user definable amount (adj.

RS-Sensor Termination Detail The RS Sensor is remotely mounted and installed (up to 500ft) in the zone it is recommended to use shielded cable (20AWG conductors) if installing RS-sensor only. If BACview is installed remotely using the same cable is recommended to use shielded cable (18AWG conductors).
The RS-Pro Sensor interface The RS-Pro sensor factory part number 641-230 is a combination keypad/display unit that attaches to a control module to let you view and change temperature and set points values and the controller’s components status, the following features only apply to the software version covered on this manual.
