Important safety information and installation precautions
Read all instructions
Failure to follow all instructions may result in equipment damage or a hazardous condition. Read all instructions carefully before installing equipment.
Local codes and practices
Always install equipment in accordance with the National Electric Code and in a manner acceptable to the local authority having jurisdiction.
Electrostatic sensitivity
This product and its components may be susceptible to electrostatic discharge (ESD). Use appropriate ESD grounding techniques while handling the product. When possible, always handle the product by its non-electrical components.
High voltage safety test
Experienced electricians, at first contact, always assume that hazardous voltages may exist in any wiring system. A safety check using a known, reliable voltage measurement or detection device should be made immediately before starting work and when work resumes.
Lightning and high-voltage danger
Most electrical injuries involving low-voltage wiring result from sudden, unexpected high voltages on normally low-voltage wiring. Low-voltage wiring can carry hazardous high voltages under unsafe conditions. Never install or connect wiring or equipment during electrical storms. Improperly protected wiring can carry a fatal lightning surge for many miles. All outdoor wiring must be equipped with properly grounded and listed signal circuit
!while standing in water.
Wiring and equipment separations
All wiring and controllers must be installed to minimize the possibility of accidental contact with other potentially hazardous and disruptive power and lighting wiring. Never place 24VAC or communications wiring near other bare power wires, lightning rods, antennas, transformers, or steam or hot water pipes. Never place wire in any conduit, box, channel, duct or other enclosure containing power or lighting circuits of any type. Always provide adequate separation of communications wiring and other electrical wiring according to code. Keep wiring and controllers at least six feet from large inductive loads (power distribution panels, lighting ballasts, motors, etc.). Failure to follow these guidelines can introduce electrical interference and cause the system to operate erratically.

About the BACnet FF
The Honeywell BACnet FF (models TB3026B and TB3026B-W) is a communicating sensor/fixed application controller with built-in humidity sensor. The TB3026B-W is the wireless version with an onboard wireless receiver for wireless occupancy control.
Electrical inputs and outputs wire directly to field equipment. The BACnet FF comes pre-loaded with nineteen applications that support common uses. These applications can be selected and some of the parameters adjusted at the controller without the need for a BACnet front end.
Operational information and control data is available to other building controllers and systems through the BACnet protocol (ANSI/ASHRAE standard). This enables a BACnet FF to share data and execute commands initiated from other BACnet-compliant devices.

Terminals and wiring
The BACnet FF label identifies wiring terminals by number and function. Terminals are numbered from top to bottom, beginning with 1 on the upper right side of the wallplate and continuing top-to-bottom on the right side of the controller. I/O terminals carry an additional numeric identifier that corresponds to the software I/O. Use this section to identify terminals on the BACnet FF. See later sections for more specific instructions, cautions, and recommendations.
Power supply terminals
Use terminals 1 and 5 to connect the 24VAC power supply to the BACnet FF.
Ground terminals
These terminals are used for terminating the grounded leg of the 24VAC circuit and the return grounds of BOs.
COM terminals
These terminals are used for terminating the return grounds of AIs and AOs.
Universal inputs (AIs)
Use these terminals (in conjunction with adjacent GND terminals) to connect universal inputs. Input terminals accept a variety of signal types.
Binary outputs (BOs)
Use these terminals to connect BO loads (ON/OFF control). Terminate the BO return ground to the panel/enclosure ground or a GND terminal on the BACnet FF.
WARNING! Do not apply line voltage to source pins.
Analog outputs (AOs)
Use these terminals to connect AO-loads (modulating control). The AO-return ground must terminate to the nearest GND terminal.
MS/TP LAN terminals
Use terminals 11(MS/TP-) and 12 (MS/TP+) to connect the BACnet MS/TP LAN to the BACnet FF. Maintain polarity throughout the entire LAN. See “MS/TP LAN Wiring” on page 16 for more information.

Installation and Operations Guide | Terminals and wiring
Using terminal blocks
The BACnet FF uses header-style termination blocks to simplify field wiring of power, communications, and I/Os. Terminal blocks accept wire gage from 12–24AWG.
To terminate wire to a BACnet FF
1.Strip approximately 1/8” of the wire jacket from the end of the wire.
2.Use a small screwdriver (1/8” max) to turn the adjustment screw fully counter-clockwise. The clamps in the wire slot separate as you turn the screw.
3.Insert the stripped end of the wire into it (try to get the jacket flush with the terminal block). If using stranded wire, be sure to insert all strands into the wire slot. If terminating multiple wires, trim wires to same length and tightly twist exposed wire together.
4.Hold the wire in place and turn the adjustment screw clockwise to tighten it until the clamps in the wire slot secure the wire.
5.Tug gently on the wire to ensure it is secure.

Installation and Operations Guide | BACnet FF
Power supply guidelines and requirements
BACnet FF uses 24VAC power from a UL Listed Class 2 24VAC transformer (not provided). The BACnet FF uses a half-wave rectifier to convert the AC power supply to onboard power. This enables multiple BACnet FFs with half-wave power supplies to be powered from a single, grounded transformer.
CAUTION Half-wave devices and full-wave devices must not use the same AC transformer. If a BACnet FF will share its power supply with another device, make sure that the other device utilizes a half-wave rectifier and that polarity of wiring is maintained. Failure to do so can result in equipment damage.
Figure 7 Internal BACnet FF power wiring schematic, half-wave rectifier
BACnet FF power ratings
The BACnet FF minimum current draw is 24 VAC @50ma leading to ~1.2VA.
The minimum applies when the BACnet FF supports no binary output (BO) loads. If the BACnet FF supports AOs, the minimum VA rating includes the draw of all AO-loads energized at maximum rating. The maximum power draw is the minimum VA rating plus the power draw when all BOs are energized at maximum capacity.
Selecting a transformer
The safest way to size a transformer is to ensure that the maximum VA load rating of the BACnet FF is less than 85% of the Nameplate VA rating of the transformer. Even if all outputs are not presently used, this ensures that each BACnet FF has sufficient power for future equipment additions.
IMPORTANT Transformer sizing should never exceed the maximum UL Class 2 rating.
Power supply grounding and wiring
When connecting power to the BACnet FF, ensure that one leg of the VAC secondary circuit connects to a known earth ground. Also ensure that the GND terminal on the BACnet FF connects to the same known earth ground.
Supplying a high-quality ground connection to a BACnet FF and then properly connecting the BACnet FF to the ground is one of the most important things you can do to ensure a trouble-free installation.
The 24VAC secondary leads are not interchangeable. Once a lead connects to the GND terminal on the BACnet FF, it is the grounded lead. Observe and maintain polarity for subsequent connections. The GND terminal provides a reference ground for the circuit board and communications wiring. Use 18 AWG cable for best results.

Installation and Operations Guide | Power supply guidelines and requirements
WARNING Ensure that all BACnet FF power, communications, and I/O cabling are grounded according to these instructions. Failure to follow these instructions may result in BACnet FF operational and communication failures or equipment damage.
Power supply wire selection
If you are considering long power supply wiring runs, using the right wire size is critical. If the wire is too small, the resistance may be too high, resulting in a low voltage supply to the BACnet FF. This is known as line loss. The wire size is based on the length of the wire run and the current draw of the BACnet FF. Use Figure 8 to determine wire size; obtain additional information from the transformer manufacturer.
Figure 8 BACnet FF wiring recommendations
Backup power
The BACnet FF features a built-in supercapacitor that will run the on-board clock for ten days in the event of power loss.

MS/TP LAN Wiring
The BACnet FF communicates on the site-wide BACnet system over a twisted-pair MS/TP LAN, which uses the EIA–485 signaling standard. BACnet FFs are master devices on the MS/TP LAN.
Each BACnet FF employs a high-quality EIA–485 transceiver and exerts ¼ unit load on the MS/TP LAN.

Installation and Operations Guide | MS/TP LAN Wiring
Grounding the MS/TP LAN shield
Proper shield grounding of the MS/TP cabling can help minimize the risk of communications problems and damage to equipment because of transient voltage spikes (for example, lightning strikes).
Follow these guidelines for grounding MS/TP cable shields:
•Each MS/TP segment should have a single point of shield ground, preferably as close to the middle of the cabling run as possible.
•Do not ground the MS/TP shield using a BACnet FF terminal.
•Never ground both ends of a shield; differences in potential between the grounds may induce current on the shield, causing interference.
•At termination connecting points, tie the shield through with a wire nut.
•At ungrounded, exposed shield points (the end of a segment), tape back the shield to the wire jacket or, for optimum transient shunting, use 100V gas discharge tubes or 120V MOVs between shield and ground.
Terminating resistors
Matched terminating resistors wired across MS/TP+ and MS/TP– are required at the last device on each end of the MS/TP segment for signal integrity (Figure 9).
Optimum segment performance typically requires “tuning,” a process by which the value of the terminating resistors is selected based on the wave form of signals on the segment. View wave forms using an industrial scope meter. The goal is to have as square a wave form as possible with an amplitude greater than 200 mV. Resistors affect the wave form as follows:
•When the resistance value decreases, the amplitude of the wave form decreases and becomes more square.
•When the resistance value increases, the amplitude of the wave form increases and becomes less square.
Typically, precision resistors in the range 80-130 Ohms (+1%) yield acceptable results. Ideally, the value of the terminating resistors should match the rated characteristic impedance of the installed cable. For example, if the installed MS/TP cable has a listed characteristic impedance of 100 Ohm, install 100 Ohm matched precision resistors.
CAUTION Do not mismatch terminating resistors. Ensure that both resistors on a segment have the same value.
Note Typically, White is Data - and Black is Data +.

Pairing a sensor to a wireless BACnet FF
The BACnet FF and wireless sensor kits (WSK-24) ship unpaired, verified by two dashes in the Sensor Status field on the BACnet FF’s Wireless Sensor Setup screen. To pair them, issue a pairing command from the BACnet FF and then activate the sensor.
Accessed from Field Service Mode, the BACnet FF’s Wireless Sensor Setup Mode includes diagnostic screens for configuration and checkout of associated sensors. With :UC displayed in Field Service Mode, press the blank key (blank area) just to the left of the blank center key, and then press the down arrow key next to the :UC parameter.
Door/window sensors may be paired to any available sensor number in the range 1-8. When cycling through sensor numbers on the Wireless Sensor Setup screen, unpaired sensor numbers show a status of --.
PIR sensors may be paired to any available sensor number in the range 1-3.

Figure 12 Wireless Sensor Setup screen
To pair a sensor to a BACnet FF
1.Make sure the battery is installed and activated in the sensor.
2.If the sensor is a door/window switch, align the magnet so that the sensor is in the closed position. If the sensor is a PIR sensor, cover the PIR.
IMPORTANT! Verify that the sliding door/window contact is closed and cover all other PIRs to prevent interference during the pairing process.
3.On the BACnet FF select the sensor to pair and then press Reset. The RESET key disappears and WAIT is displayed indicating that the BACnet FF is waiting to pair the sensor with the next device that receives a radio signal.
4.Activate the sensor you want to pair.
Note Pairing times out after 10 seconds of no pairing activity.
5.Verify that the BACnet FF and sensor successfully paired. Paired = sensor status is displayed, replacing --.
Timed out = RESET is displayed and sensor status is --.
Figure 13 Door sensor number 1 paired and in closed status.
To erase sensor-to-BACnet FF pairings
1.While viewing any sensor status screen while pairing is not taking place, press the blank key to the left of CANCEL.
2.Press the blank key to the right of DONE.
The sensor status field displays --, indicating unpaired.

Installation and Operations Guide | BACnet FF
Fixed field service codes
Field service mode enables technicians to query and command key operating variables in the BACnet FF while at the BACnet FF touchscreen. A technician presses a particular key sequence at the BACnet FF to enter field service mode. In field service mode a technician uses the left arrows to scroll through data codes and the right arrows to change the value associated with a code.
The lower left of the LCD shows the two-digit data code and the main area displays the data value. A pre-defined list of data codes is available within the description of each application. See Table 8 as an example for applications 0 and 1. “Configuring a DDCMULTI application” on page 27 provides more information about these settings.
Note When using the local user interface to change applications (AV-49), the application defaults will NOT change and must be changed manually.
You can deny users access to field service mode by setting BV-68 to ON. You can also require a PIN code in order to enter field service mode by setting AV-132 to the desired PIN number.
Field service mode ends automatically if there is no key activity for five minutes.
Setting field service codes
To set field service codes
1.From the home screen, press SYSTEM (left side of the screen).
2.Press and hold the center bottom key (blank) for about five seconds. See Figure 10.
3.If a PIN code is required, use the top arrows to select the first two digits of the code and the bottom arrows to select the third and fourth digits of the code, and then press DONE.
The field service screen appears.
4.Press the left up or down arrows until the desired code appears. See Table 8 on page 42 for the list of Setup Codes. NOTE: All applications use the same Setup Codes.
5.Press the right up or down arrows to adjust the value associated with the code.
6.Press the left up or down arrows to accept the change and scroll to a different code.
7.Press DONE to exit field service mode.

Installation and Operations Guide | Operational overview
Operational overview
The BACnet FF operates in one of three modes - Setpoint, Occupancy Single Setpoint, and Occupancy Dual Setpoint.
Common features
This section describes features common to all operating modes. For descriptions of mode-specific features, see “Checking MS/TP communication” on page 26 and “Checking MS/TP communication” on page 26.
LCD backlight operation
BV-79 controls backlight operation. If BV-79 is OFF, the backlight turns ON when any key is pressed and stays on for 20 seconds after there is no key activity. If BV-79 is ON, the backlight is ON continuously.
Clock operation
The BACnet FF’s real-time clock provides time and date for displaying the date and time, implementing daylight savings settings, and implementing schedules. If AC power is lost, a supercapacitor will power the clock for ten days. If the date and time are lost, the BACnet FF will display the set time and date screens when powered up.
Note The real-time clock is separate from the CPU time keeping utility. It only affects the items listed in this section.
Daylight savings (DLS) settings can be controlled by a BACnet FF or by a
BACnet Supervisor. If installer setup (ISU) parameter 330 is set to non-zero, the
BACnet FF will control DLS settings. If ISU 330 is zero, DLS is controlled by a
BACnet Supervisor.
The clock accepts time syncs from a BACnet Supervisor. If configured in DDC, the date and time can also be set manually using the display. To deny a user permission to set the clock, set BV-116 to 1.
The last time command, whether from the user screen or BACnet, takes precedence.
To adjust the real-time clock
1.Press CLOCK.
2.Use the arrow keys to select a year, month, and day.
3.Press DONE.
4.Select a time.
5.Press DONE.

Installation and Operations Guide | BACnet FF
MORE key navigation
The MORE key allows a programmer to make additional screens available to users. Enabling the display of one or more of these screens causes the MORE key to appear on the main screen. The screens that can be made available are:
•Outside air temperature
•Inside/outside humidity
When the user presses MORE, the first enabled screen appears. Pressing
MORE again displays the next screen.
Touchscreen cleaning
If the display screen needs to be cleaned, the user presses SCREEN. The display will lock for 30 seconds allowing the user to wipe the screen without pressing any keys. When the display reads 0, press SCREEN to continue cleaning or DONE to quit. Use a non-abrasive glass cleaner.
Checking MS/TP communication
You can check MS/TP communication from the display. The BACnet FF will indicate if MS/TP packets and headers have been seen, the baud rate, and the MAC address.
To check MS/TP communication
1.Enter field service mode. See “To set field service codes” on page 24.
2.Ensure the UC code is displayed.
3.Press the blank key usually labeled MORE (bottom row, second from right).
4.Press the down arrow near the UC code. The MS/TP communication screen appears.

Installation and Operations Guide | Configuring a DDCMULTI application
Configuring a DDCMULTI application
The BACnet FF is pre-loaded with DDC that lets you select one of multiple applications. Applications for heat pumps, A/C units, and fan coil units are all contained in the same DDC file. Using one of these applications, an installer can configure the controller in the field - just set the MS/TP parameters, device instance, and application [AP] (AV-49) parameters and it is ready to go.
Note When using the local user interface to change applications (AV-49), the application defaults will NOT change and must be changed manually. However, The Niagara-based configuration wizard will change the application specific default values.
Advanced application settings will require a BACnet connection to a BACnet BMS. These detailed application settings need to be reviewed to ensure all are set correctly before enabling the device's outputs.
CAUTION Setting the [OE] field service code to ON powers up the outputs. Ensure that the outputs are configured correctly before setting OE to ON.Failure to do so may result in equipment damage.
1.Set field service code [OE] (BV-2) to ON to power up the outputs.
2.Press DONE.

Sequences of Operation
Controller outputs are disabled when Enable Outputs [OE] BV-2 OF/On is in the OF (inactive) state. Do not enable outputs until you are certain the wiring and configuration is correct and complete.
SYSTEM Block Control (BV-102)
When the unit is configured to run in Occupancy Mode, the SYSTEM Block allows the user direct control of occupied or unoccupied state from the controller display. Selecting “Auto” places the controller in Occupied state. Selecting “OFF” places the controller in unoccupied state.
The SYSTEM Block can be hidden by setting BV-102 inactive. When the SYSTEM Block is hidden occupancy states are controlled exclusively by the onboard or BMS schedules.
