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.

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.

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 6 – Rotary switches

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.

PROTOCOLS SW3 SW4

BACnet®MS/TP Off Off

N2 On Off

Modbus Off On

Option Card On On

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.

IMPORTANT:

The LonTalk® card

must be installed.

section.

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.
