The TB7200 Series PI thermostats are designed for zoning

applications, and the TB7300 Series PI thermostats are

designed for fan coil control. Both Series are communicating

thermostats with models available in BACnet MS/TP and

ZigBee wireless mesh protocols and can be easily

integrated into a WEBs-AX building automation system based

on the NiagaraAX platform.

TB7200 and TB7300 Series thermostats are compatible with

the Honeywell Occupancy Sensor Cover. Thermostats

equipped with an occupancy sensor cover provide advanced

active occupancy logic, which will automatically switch

occupancy levels from Occupied to Stand-By and Unoccupied

as required by local activity being present or not. This

advanced occupancy functionality provides advantageous

energy savings during occupied hours without sacrificing

occupant comfort. All thermostats can be ordered with or

without a factory installed PIR cover.

TIPS AND THINGS YOU NEED TO KNOW

•

Each thermostat is delivered from the factory with the default MAC address set at 254. At this value, BACnet communication is

NOT active and the device will not participate in the token pass either. The local LED status for the communication adapter at

this point is one short flash only. To enable BACnet communication, set the local MAC address configuration property of the

thermostat to any valid value from 0 to 127.

•

After the initial configuration of your device and if your BAS allows you to remove objects, we suggest that you remove all the

configuration objects to prevent unnecessary polling of non used objects and to help speed up the network.

All configuration objects are available and accessible locally from the device itself using the local configuration routine. Please

refer to the PIR Application Guide for TB7200 and TB7300 Series Thermostats (form number 63-4526).

In its default mode of operation, the device will automatically match its baud rate to the baud rate of the network. Automatic

baud rate detection will occur when the MS/TP communication port is initialized (on power up). If the network speed is

changed, the device will keep listening at the previously detected speed for 10 minutes before resuming auto-bauding. Re-

powering the devices will force immediate auto-bauding.

•

Enumeration sets for System Mode MV16 depends on Sequence of Operation (MV15) value upon device discovery. If

required enumerations are not present, set MV15 to desired value and rediscover MV16 object. Available enumeration will

now reflect required configuration.

Enumeration sets for MV16 depends on Fan Mode Sequence (MV58) value upon device discovery. If required enumerations

are not present, set MV58 to desired value and rediscover MV16 object. Available enumeration will now reflect required

configuration.

Enumeration sets for MV26 and MV27 depend on Control Type (BV75) value and Pipe Number (MV52) value upon device

discovery. If required enumeration is not present, set BV75 and MV52 to desired value and rediscover MV26 and BV27 object.

Available enumeration will now reflect required configuration.

If the device should go off-line, the following binded thermostat parameters will be released:

•

Room Temperature

Outdoor Temperature

Occupancy

•

The BACnet Data Link layer has two key parameters: the device object name and the device object ID. The device object

name must be unique from any other BACnet device object name on the BACnet network (i.e. not just the MS/TP sub-

network). The device object ID must be unique from any other BACnet device object ID on the entire BACnet network (i.e. not

just the MS/TP sub-network).

63-4524—01

BACNET INTEGRATION MANUAL FOR TB7200 & TB7300 SERIES THERMOSTATS

•

To assign a Room Temperature (AV7) value manually, users must first enable the Override mode in the Room Temp Override

(BV8) object.

To assign a Room Humidity (AV10) value manually, users must first enable the Override mode in the Room Humidity Override

BV11) object.

(

Device Name and Device ID properties are writable in Honeywell device object. Both properties can be renamed from any

BACnet network management tool as long as the tool itself give access to write to these properties.

WIRING GUIDELINES

Overview

Honeywell uses EIA-485 as the physical layer between their devices and supervisory controllers

For clarity we will use the term “Device” to represent any product with an active EIA-485 network connection, including Honeywell

and non-Honeywell thermostats.

Cable Type

Honeywell recommends the use of balanced 22-24 AWG twisted pair with a characteristic impedance of 100-130 ohms,

capacitance of 30 pF/ft or lower. A braided shield is also recommended.

Impedance

A value based on the inherent conductance, resistance, capacitance and inductance that represent the impedance of an infinitely

long cable. The nominal impedance of the cable should be between 100Ωand 120Ω. However using120Ω will result in a lighter

load on the network.

Capacitance (pF/ft)

The amount of equivalent capacitive load of the cable, typically listed in a per foot basis. One of the factors limiting total cable

length is the capacitive load. Systems with long lengths benefit from using low capacitance cable (i.e. 17pF/ft or lower).

63-4524—01

BACNET INTEGRATION MANUAL FOR TB7200 & TB7300 SERIES THERMOSTATS

NETWORK CONFIGURATION

EIA-485 networks use a daisy chain configuration. A daisy chain means that there is only one main cable and every network

device is connected directly along its path.

Figure 1 illustrates two improper network configurations and the proper daisy chain configuration.

Other methods of wiring an EIA-485 network may give unreliable and unpredictable results. There are no troubleshooting

methods for these types of networks. Therefore, a great deal of site experimentation may have to be done, making this a difficult

task with no guarantee of success. Honeywell will only support daisy chain configurations.

BUS CONFIGURATION

M32571

Fig. 1. Three different network configurations: star, bus, and daisy chain.

Only the daisy chain configuration is correct for an EIA-485 network.

Maximum Number of Devices

A maximum of 64 nodes is allowed on a single daisy chain segment. A node is defined as any device (controller, thermostat,

repeater, etc.) connected to the RS485 network. Terminators do not count as a node.

NOTE: Biasing is not required with this series of devices.

To determine the number of nodes on a network, add the following:

•

One node for each device, including the controller

One node for each repeater on the chain

For the example in Figure 2, we have one node for the controller, plus 4 for the thermostats for a total of 5 nodes.

BACNET INTEGRATION MANUAL FOR TB7200 & TB7300 SERIES THERMOSTATS

Maximum Cable Length

The maximum length of a chain is related to its transmission speed. The longer the chain, the slower the speed. Using proper

cable, the maximum length of an EIA-485 daisy chain is 4000-ft (1200 m). This will only work reliably for data rates up to 100,000

bps. The maximum data rate is 76,800 bps for TB7200 and TB7300 Series thermostats.

If you require a maximum network length of more than 4000 feet, then repeaters are required to extend the network.

EIA-485 Repeaters

If you have more than 64 devices, or require a maximum network length of more than 4000 feet, then repeaters are required to

extend the network. The BASRT-B repeater by Contemporary Controls can be used if a repeater is needed. The best

configuration is to daisy chain the repeaters to the controller. From each of these repeaters, a separate daisy chain will branch

off. Figure 3 demonstrates a valid use of repeaters in an EIA-485 network.

End Of Line (EOL) Resistors

MS/TP network must be properly terminated. For daisy chain configurations, you must install an EOL resistor at each end of the

daisy chain. Depending on your MS/TP network configuration, the resistance value of the EOL resistor may change:

•

TB7200, TB7300, or TB7600 Series devices are installed at both ends of the MS/TP network:

120 Ohms resistor should be installed at each end.

•

A TB7200, TB7300, or TB7600 device is installed at one end of the MS/TP network and another device is installed at the other

end:

Install an End-Of-Line resistor value that matches the other device’s instructions regarding its EOL resistor value;

•

Other devices are installed at both ends of the MS/TP network:

Follow the other device’s instructions regarding its EOL resistor value.

NETWORK ADAPTER

The polarity of the connection to the cable is important. From one module to the other it is important that the same colored wire be

connected to “plus” or “+” and the other colored wire be connected to the “minus” or ”-“. Figure 5 shows the proper MS/TP

connections and the location of the Status LED. This Status LED may help to troubleshoot network problems.

Fig. 5. Correct MS/TP connections and location of a Status LED on a BACnet module

IMPORTANT NOTE: The Ref terminal should NEVER be used to wire shields. The 2 shields from each feed of the network

connection to a thermostat should be wired together in the back of the thermostat and properly protected to prevent any

accidental connection to the ground.

The joined shield connection should then be grounded at a SINGLE point on the whole segment. More than one ground

connection to a shielded wire may induce ground loop noises and affect communication.

Configuration Objects

The following objects and group objects should be typically used for configuration purposes:

•

General Options 1 Group GRP 45 and its complete list of objects;

General Options 2 Group GRP 55 and its complete list of objects;

Humidity Models Configuration Options Group GRP 69 and its complete list of objects;

Output Configuration Options Group GRP 74 and its complete list of objects.

If your BAS allows you to remove objects, Honeywell recommends removing all configuration objects once your setup is

complete. This will prevent unnecessary network polling and traffic.

Default Device Name and default Device ID

Default Device Name is set to: Model number – MAC:

•

Where MAC is the current MAC address of the device.

Where Model number is Honeywell part number.

The device name will be upgraded as soon as there is a change to the device MAC address.

The Device Name and Device ID properties are writable in Honeywell device object. Both properties can be renamed from any

BACnet network management tool as long as the tool itself can write to these properties.

TB7200 Models

Default Device ID is set to: 72000 + MAC

•

Where MAC is the current MAC address of the device.

The device ID will also be upgraded as soon as there is a change to the device’s MAC.

For example, when a TB7200F5014B thermostat with a MAC address of 41 is connected to a network, its default Device Name

will be TB7200F5x14B-41 and its default Device ID will be 72041.

TB7300 Models

Default Device ID is set to: 73000 + MAC

•

Where MAC is the current MAC address of the device.

The device ID will also be upgraded as soon as there is a change to the device’s MAC.

For example, when a TB7300C5014B thermostat with a MAC address of 63 is connected to a network, its default Device Name

will be TB7300C5x14B-63 and its default Device ID will be 73063.

Integrating Honeywell Devices on an MS/TP Network

Before doing any BACnet integration, make sure to have Honeywell PICS (Protocol Implementation Conformance Statement).

This PICS document lists all the BACnet Services and Object types supported by a device and can be found at

http://customer.honeywell.com.

Honeywell devices do not support the COV service. COV reporting allows an object to send out notices when its Present-Value

property is incremented by a pre-defined value. Since this is not supported at Honeywell’s end, special attention should be given

to the polling time settings at the Supervisory Controller and Workstation level when using a graphic interface or an application

program to read or write to a Honeywell object.

63-4524—01

BACNET INTEGRATION MANUAL FOR TB7200 & TB7300 SERIES THERMOSTATS

Graphical interfaces

For example, some graphic interface might poll every data linked to the graphic page on a COV basis. If the 3 party device does

not support COV, the graphic interface then relies on a pre-configured polling interval, which is usually in hundredths of

milliseconds. Any device containing a monitored object could be subject to network traffic congestion if such a polling interval is

used. Honeywell strongly recommends a polling interval of 5 seconds minimum for any graphic interface. This becomes even

more critical in area graphics where a single representation might poll many devices. If proper poll rate is not respected, devices

may be reported offline by certain front end by saturating the traffic handling capacity of BACnet MS/TP without COV

subscription.

Free programmed object or loops

As for the application program, you might want to read and write any MS/TP data on an “If Once” basis or a “Do Every” loop basis

instead of reading or writing to a 3 party device’s object directly in the program. Otherwise, any read or write request will occur

at the Supervisory Controller’s program scan rate, which might as well be in hundredths of milliseconds. This can easily bog

down a network as single commands can be sent to all ASC devices down the MS/TP trunks every hundredth of milliseconds

Programs writing to the devices should have a structure similar to the following:

If Once Schedule = On then

MV13 = Occupied

End If

If Once Schedule = Off Then

MV13 = Unoccupied

End If

Do Every 5min

If Schedule = On Then

MV13= Occupied

Else

MV13 = Unoccupied

End If

End Do

Retries and Timeouts

Another thing to look for in a BACnet integration is the Device object of the Supervisory Controller (and the Operator’s

Workstation). This object contains the 2 following required properties: Retry Timeout and Number of APDU Retries.

The Retry Timeout property specifies the time between re-transmissions if the acknowledgement has not been received.

When you are experiencing problems with controllers dropping off-line, increasing this value may help.

The Number of APDU Retries property specifies the number of times unsuccessful transmissions will be repeated. If the

receiving controller has not received the transmission successfully after this many attempts, no further attempts will be

made.

For example, if one of the thermostats does not reply to a Supervisory Controller (SC) request, and the SC’s Retry Timeout is set

to 2000 msec and the Number of APDU Retries is set to 1 (still at the SC level), then the SC will send one other request, 2 sec

later. If the MS/TP device does not reply, it will be considered Off-line by the workstation.

So having a Retry Timeout value of 10000 msec and a Number of APDU Retries property set to 3 at the SC level may prevent

device from dropping Off-line. These properties should also be changed at the Workstation level since the workstation will likely

issue requests to any MS/TP devices when the graphics are used.
