The Zone Controller
The Zone control board also known as DDC
and shown in figure 1 is used in most
configure to order applications.
It is BACnet® native which makes it flexible
and easy to integrate into existing Building
Automation Systems (BAS). The main
difference between the 560 and the I/O 583
is the Analog Output (AO) plug enclosed in
figure 1.
The controller is programmed in the factory
with software versions that suit the different
applications FHP offers. User settings such
as the time and test and balance set points
shall be set up during the installation and
commissioning process at the job site.
Figure 1 - Zone Controller
Analog plug enclosed in red box on figure above is only available on Zone I/O 583.

LED IndicatorsLED Indicators
The DDC controller is equipped with three
bank sets of LED that help the user
diagnose problems and or identify normal
operation.

Figure 2 - Network LEDsFigure 2 - Network LEDs
The first bank is located in the upper left
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. The first one from top to bottom
is normally lit (on) while the controller is
powered the second is the heart beat and
will flash during normal operation, the third
LED will remain off and will lit red in case
there is an error in the controller.

In addition, when downloading new or
modified versions of software these LEDs
will flash on and off indicating new files are
being written to its non-volatile memory.

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
Two sets of switches can be found on the
controllers, they must be set properly to
allow correct operation of the unit.
The first set are rotary switches, as shown in
figure 5, is located on the left hand corner
near the top and their function is to provide
the controller address it always convenient
to identify the rotary for the tens and the
rotary for the ones as shown in figure 6.
The second set is located on the top left
hand corner of the controller and it is used
for two purposes:
(1) SW1 and SW2 set the baud rate of the
communications port on the controller:
BAUD RATE SW1 SW2
9600 Off Off
19.2K Off On
38.4K On Off
76.8K On On
Figure 5 – Controller Address Rotary DIP switch

Figure 7 – DIP Switches
(2) SW3 and SW4 enable different
supported protocols on the controller
additional hardware is needed for LonTalk®.
IMPORTANT:
Controllers must be
addressed correctly
for multiple units to
work on a network.

Typical DIP switch for LonTalk® (Option
Card) is shown in figure 8.
Jumpers and settings
Controllers come equipped with a series of
jumpers which allow different types of inputs
to be terminated in a particular point.
Most inputs allow thermistor or dry contact
input devices to be terminated in them,
however IN1 and IN2 can be used as analog
or digital input points and their available
options are as follows:
0-5 VDC Analog Input
Thermistor
Dry Contact
FHP sets most switches in the factory,
however there are certain cases where a
particular sensor is required by the
customer, therefore it is important for the
installer to understand jumper settings and
their relationship with unit configuration and
operation. Figure 9 shows the location of the
jumpers on the controller.

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.
The Lon card connects to the option card port as shown in figure 11.

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).
The point mapping to all of these protocols is available in www.fhp-mfg.com and can be pre-set,
so that the protocol and baud rates desired can be easily field-selected and commissioned
without the need for any additional downloads or technical assistance.
The DDC Controller also supports communications to intelligent RS Room sensors and
BACview keypad/display panels.
Key Features and Benefits
I/O point count: 5 Digital outputs and 6 Universal inputs
Powerful high speed microprocessor with 1MB Flash memory and 1MB of battery-backed
RAM
Built-in protocol support: BACnet® (ARCNET and MS/TP), Modbus, N2 and LonWorks®
(additional network interface board required for LonWorks® option)
Built-in local access support: BACview6 keyboard/display and Intelligent RS Room
sensors
On-board lithium battery holds Controller time clock settings
Program archived in non-volatile memory allows unit to be ready after long periods of
power outages.
