PRODUCT DESCRIPTION

The PUB and PVB controllers are part of the Spyder family.

These controllers are BACnet MS/TP network devices

designed to control HVAC equipment. These controllers

provide many options and advanced system features that

allow state-of-the-art commercial building control. Each

controller is programmable and configurable through 

software.

The Spyder BACnet controllers require the Spyder BACnet

Programmable Feature to be licensed in the WEBpro

workbench tool and the WEBS AX JACE Controller for

programming and downloading. The Spyder BACnet

Models are also available as Individually Licensed

Controllers (ILC). The ILC versions are identical in design

and capability in every detail except for the licensing. The

Individual Licensing of the Spyder ILCs (the License is

built in) allows them to be programmed and downloaded

with any brand of the Niagara Workbench or JACE

controller. The Spyder ILCs are identified with a suffix on

the Part Number of -ILC. Example: PUB6438S-ILC follows

all the same Installation Instructions information as the

PUB6438S.

These controllers are for use in VAV (Variable Air Volume),

Unitary and advanced HVAC control applications. Each

controller has flexible, universal inputs for external

sensors, digital inputs, and a combination of analog and

digital Triac outputs. All the models are described in Table

1. The photo to the left is the model PVB6436AS, which

includes the actuator.

Key Features and Benefits

• Bi-directional sensing capability: Allows use in applications where bidirectional

flow is present

• Highly stable null and full-scale: Does not require recalibration in most applications

Airflow Sensors

AWM90000 Series microbridge mass airflow sensors are available in two versions,

mass flow and differential pressure. The AWM92100V has a flow range of ±200

SCCM with a pressure drop of only 0.49 mbar | 49 Pa | 0.007 psi, typically.

The AWM92200V is a differential pressure version that has a range of ±2 inH2O.

The AWM90000 Series sensors have a 1 ms response time, operate with a supply

voltage from 8.0 Vdc to 15.0 Vdc, while consuming only 50 mW of power.

The compact plastic package will withstand a maximum overpressure of 1720

mbar | 72 kPa | 25 psi without compromising performance. The sensor is well

suited for use in portable devices and battery powered applications.

The AWM90000 Series provides customers with a combination of time-proven

reliability, repeatable flow sensing, and the ability to customize the sensor

functions to meet their specific application needs.

Customizable flow ranges and configurable package styles meet specific end-user

needs. Full calibration and temperature compensation typically allow customer

to remove additional components associated with signal conditioning from the PCB,

reducing PCB size as well as costs often associated with those components (e.g.,

acquisition, inventory, assembly). High sensitivity at very low flows provides for

faster response time at the onset or cessation of flow. Linear output provides

a more intuitive sensor signal than the raw output of basic airflow sensors,

which can help reduce production costs, design, and implementation time. High

stability reduces errors due to thermal effects and null shift to provide accurate

readings over time, often eliminating need for system calibration after PCB

mount and periodically over time. Low pressure drop typically improves patient

comfort in medical applications, and reduces noise and system wear on other

components such as motors and pumps. High 12-bit resolution (digital) increases

ability to sense small airflow changes, allowing customers to more precisely control

their application; 0.039 %FS resolution (analog) increases ability to sense small

airflow changes, allowing customers to more precisely control their application.

industrial (e.g., fume hood) applications. Measures mass flow at standard flow

ranges of ±50. ±100. ±200. ±400 or ±750 SCCM, or custom flow ranges,

increasing the options for integrating the sensor into the application.

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.

• Wide range of airflows

• Customizable flow ranges and configurable package styles

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.
