Go with the flow of engineering leadership. All airflow sensorsoperate on heat transfer

— flow and differential pressure.

But Honeywell Sensing and Control (S&C) offers advanced chip design, manufacturing

 techniques and microstructure technology, allowing our microbridge to be notably faster,

smaller and more sensitive. Our silicon chip design is created from a thin film, thermally

isolated bridge structure, containing both heater and temperature sensing elements.

This provides rapid response to the air or gas flow and amount and direction, delivering

a proportional output voltage. Amplified versions provide an enhanced output signal

and less external circuitry, while unamplified versions allow additional external circuit

options.

What’s more, a variety of port styles provides greater application flexibility.

Honeywell ZephyrTM Digital Airflow Sensors

HAF Series – High Accuracy

Honeywell Zephyr™ HAF Series sensors provide a digital interface for reading airflow over specified full-scale flow and

compensated temperature ranges. The thermally isolated heater and temperature sensing elements help these sensors

provide a fast response to air or gas flow.

Zephyr sensors are designed to measure mass flow of air and other non-corrosive gases. Standard flow ranges are

available at ±50. ±100. ±200. ±400 or ±750 SCCM. Custom flow ranges are also available. The sensors are fully calibrated

and temperature compensated with an onboard Application Specific Integrated Circuit (ASIC).

The HAF Series is compensated over the temperature range of 0 °C to 50 °C [32 °F to 122 °F] and operates across a

temperature range of -20 °C to 70 °C [-4 °F to 158 °F]. The state-of-the-art ASIC-based compensation provides digital (I2C)

outputs with a response time of 1 ms.

These sensors operate on the heat transfer principle to measure mass airflow. They consist of a microbridge

Microelectronic and Microelectromechanical System (MEMS) with temperature-sensitive resistors deposited with thin films

of platinum and silicon nitride. The MEMS sensing die is located in a precise and carefully-designed airflow channel to

provide repeatable response to flow.

Zephyr sensors provide the customer with enhanced reliability, high accuracy, repeatable measurements and the ability

to customize sensor options to meet many specific application needs. The combination of rugged housings with a stable

substrate makes these products extremely robust. They are designed and manufactured according to ISO 9001 standards.

What makes our sensors better?

• Fast response time

• Wide range of airflows

• Customizable flow ranges and configurable package styles

• Linear output

• High stability

• Low pressure drop

Set jumpers and scale sensors.

It is essential to set physical jumper Honeywell current

sensors. You need to match this scaling, either via 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

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.

Do not mount the C7400S, C7250A “Grey Sensors”

directly against 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 LCBS

Connect wall module or LCBS Connect Web UI. If you

don’t, CT output will read incorrectly.

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.

There can be no assurances whatsoever that the LCBS

Connect System will protect any individual or his or her

property from harm. Appropriate safety precautions must

always be taken and experienced installers and operators

must be utilized when installing, setting up, operating or

maintaining any building systems. Incorrect processes

may result in property loss, severe injury, or death.

Honeywell assumes no responsibility or liability for any

The LCBS Connect Wall Module is a Sylk bus

communicating device which is exclusively compatible

with the LCBS Connect controller. It contains integral

temperature and humidity sensors to control any given

space’s comfort. This device enables local controller

configuration through an easy-to-use touch screen

interface with menu driven selections. The wall module

communicates and is powered by the Sylk bus, so no

additional wiring is necessary.

The LCBS Connect™ controller and wall module

combination is designed to control constant volume

air handling units and heat pumps. With the embedded

control logic and integral temperature humidity sensors,

it controls the space temperature in a given zone by

regulating the heating and cooling equipment to deliver

conditioned air to that space. The LCBS Connect gateway

serves as the communication device between a building

site and the Honeywell cloud, providing contractors with

a way to remotely monitor, control, and configure

Honeywell building controllers from Honeywell’s LCBS website.
