Important Tips
Research gateway installation with your customer before installing.
If you wait to do the research during general system installation, you will find that your installation time will be unacceptable to you. Use the “Introduction to LCBS
Connect — Information Technology Background” as a resource tool with your customers in advance of your general installation.
Do not mount the C7400S, and C7250A “Grey Sensors” directly against the mounting surface.
We’ve found that sensors do not read the proper temperature and humidity readings if they are mounted directly on a surface. This is due to the radiant and convective temperature coupling of the metal surfaces to the sensor case, which causes the sensor to accurately measure an average of the surface and the air. Use the 50053060-001 sensor mounting bracket if you apply these sensors.
Address grey sensors via addressing settings before installation.
Refer to this document and other technical information to set these switches correctly before installation. If these switches are not set correctly, the sensor will fail to function properly.
Set jumpers and scale sensors.
It is essential to set physical jumper Honeywell current sensors. You need to match this scaling, either via the LCBS Connect wall module or LCBS Connect Web UI. If you don’t, CT output will read incorrectly. Set differential pressure sensors, set switches. Make sure that you set the physical switches on the Honeywell P7640 device to measure 0 to 2.5 inches of the water column. Please check this setting on the sensor. Further, you will need polyethylene tubing running to the high-pressure side of the filter. Please refer to installation information if you need help determining proper poly tube positioning relating to the filter.

Controls
Determining controls that you need to develop a complete system At bare minimum, an LCBS Connect controller and wall module are necessary to provide control of a standard constant volume air handling unit. Both devices are provided in the box and are “matched” to operate together. A 24 VAC power supply is required to power the LCBS Connect control system. In most cases this power is available from the constant volume air handling unit, in the low voltage control panel of the HVAC system.

Sylk Sensor Network

What you need to know to install the Sylk sensor network
The Honeywell “Sylk” Network and Sensors
The Honeywell C7400S and TR40, TR40-H, TR40-CO2, TR40-H-CO2, and LCBS Connect wall modules are two-wire sensors that attach to a single bus. We call it the Honeywell “Sylk” network.
Benefits and details of Sylk network:

• The total length of the Sylk network should not exceed 150 feet. There is nothing you can do about this issue. No additional power supplies can be added. The addition of additional wire capacitance (larger wire AWG), could help extend the length of the network by 20–40 feet.
• It is polarity insensitive. You don’t have to connect sensors to “plus” and “minus” consistently.
• It is powered with voltage to power the sensor. No external power supply is required. This leads into a trade-off, simply put the current available to power the sensors is limited. So, please see the table below. This represents the MAXIMUM sensors that can reside on a single Sylk network coming from a single LCBS Connect controller.

controller. Two C7400S sensors are required to perform differential enthalpy economizer controls.
TR40 TR40-H C7400S TR40-H-CO2 TR40-CO2| One TR40-H, TR40-H-CO2 or TR40-CO2 takes up power of two TR40, C7400S sensors. If you intend to do differential enthalpy control, there is only power for ONE TR40-CO2.

• Sylk sensors must be “addressed” via small switches on the device. If you don’t “address” these sensors properly, the sensors WILL NOT WORK properly.

NOTE: If the LCBS Connect wall module stops at the “90% Loading” screen upon power up, there is a Sylk Bus addressing issue. Review the additional Sylk sensor addresses before proceeding.

WIRING

Requirements and how to wire the system components to controllers

Important to determine potential line loss if a long wire run is deployed.
Connection to low voltage system control| 24 AWG 5+ to 18 AWG 5+. Terminate Y, G, R, W and multistage terminations to the LCBS Connect controller.
Sylk wire. Wall module to controller, sensors| 24 AWG 2 to 18 AWG 2. Larger wire size can mitigate the length of the wire run. Don’t exceed 150-foot wire length restriction.
Sensors to controllers| 24 AWG 2 to 18 AWG 2. All thermister sensor-based sensors, self-powered sensors. Use 18 AWG for maximum reliability.
Power sensors to controllers| 24 AWG 3 to 18 AWG 3. Sensors requiring DC power need an external power supply. Observe LCBS control power output if selecting other powered sensors.
Network cable| 22 AWG 2. Preferred Network IV cable rating. Solid, stranded preferred.

Important. If cable runs through air stream, it must be “plenum rated.” The non-plenum-rated cable can emit noxious, deadly gas into air space.
Gateway and controller wiring
Power controller 1 with the existing 24 VAC from the RTU, heat pump, or split system. Reconnect terminations 2 to heating, cooling, and fan control on the LCBS Connect controller. Reuse 3 two of the existing wires from the wire drop from RTU to the thermostat to connect the wall module to the controller via the S-Bus terminals. Additionally, install new wires, per specification 4 to “Sylk” bus connection, to install TR40, C7400S Sylk sensors. Installing the LCBS Controller Network
The LCBS Connect controller network is based on the robust LonWorks™ network. Honeywell adopted this technology in 1988 and has developed core engineering competency creating controls that use this technology, making it a popular choice for contractors. There are a few key things to remember as you develop your installation plan.
While the Echelon FTT-10 technology is quite robust and supports many different topology options, Honeywell recommends standard “daisy chain” wiring, as shown in this guide.
We recommend the “single terminated network” approach for LCBS control networks. With our 30-year experience with LON building control networks, most small networks (250 feet in length) will function without the termination module. We recommend that you add this device to keep network message reliable at high at all times. Further, make sure that you wire the termination module correctly, per the drawing below. If you don’t, controller network failure can occur.

Gateway Installation

The LCBS Connect Gateway takes data from LCBS Connect controllers, via the controller network, and sends that data over the internet to the Honeywell Cloud. Proper planning will make the installation of this device very simple.
Tips before installing

• Make sure you tell your customer and/or end-user business sponsor what you are going to do. In many cases, the customer will express concern that the “IT Manager” will have an issue with the installation of such a device.

If the customer is concerned, give them the Honeywell white paper “Introduction to LCBS Connect — Information Technology Background”. If the customer has questions about this data, call Honeywell customer service at 1-888793-8188, or your Honeywell Product Management professional.
Physical installation

1. Record the MAC ID before mounting and save it in a safe place. It is on the back of the device and mounting it using installation eyeholes could conceal it.

2. Mount the gateway one of three ways
   a. Using the eyeholes in the corners of the device, screw the gateway into a suitable metal or wood surface. Make sure to record your MAC ID before you do so.
   b. Mount the gateway on a standard DIN rail.
   c. Place the gateway on a desktop. The device features rubber mounting feet that will prevent knocking the gateway off a surface.

3. Provide power to the device using the Honeywell power supply (see parts list) or standard 24 VAC power. The device needs 10 VA to be continuously powered.

4. Connect the gateway to the internet via ethernet cable.
   Please refer to the gateway specification sheet for specific installation instructions.

Register the Gateway

If you have specific instructions, grab the “Building Registration Process” document. Log onto the LCBS Connect Web UI with the username and password that you have received sometime in the past. You can’t proceed without this information.

1. Log in to the LCBS Connect web app on any computer, tablet, or smartphone at lcbs.honeywell.com
2. Select “BUILDINGS” from the black navigation bar. Select the blue + icon.

Add Building

1. Fill in the information about the building.
   NOTE: You do not have to assign technicians at this point in time.

2. Select SAVE after completing this task.

Building Information, Assign Owner
After you have saved the building, the Web UI moves to the “Building Information” screen.

1. The interface will show “No Building Owner Assigned.”
2.  Select the “Assign Owner” button.

Assign Building Owner
After selecting the Assign Owner button, you will see a list of existing building owners.

1. Select the building owner you want by clicking the “Assign” button.
2. If the building owner you wish to assign is not listed, use the + button to add them.

Invitation Sent to Owner
It is essential that you, as your customer’s supplier, let your building owner know that this correspondence is coming to them. An “End User License Agreement” is sent to them for their approval. Once they have done this, you can register the controller.

1. Notify the building owner they will be receiving an “End User License Agreement” that must be accepted before the gateway registration can be complete.

Register gateway

1. Navigate to the CONTROLS tab of the newly created building.
2. Click the + button to add a gateway.
3. Type the eight-digit code found on the gateway
4. Wait for device registration confirmation. This may take up to 5 minutes.
5. Observe the gateway directly or call your customer and determine the status of the four LEDs. The white, amber, green, and blue LEDs should be on and steadily lit.
   • If flashing, consult the gateway documentation “Gateway Installation Instructions,” found in the box, or under the **?** icon in the web application.

Controller connections

1. If the controllers have already been connected to the LCBS controller network, they will auto-discover and display without any additional actions.
