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, 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.

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.
