APPLICATION
The 75F® Pressure Sensor Package
™
is designed to monitor the
differential pressure inside your building. Pressure in a building can be
created in several ways. Buildings are generally designed to exhaust
as much air as is being taken in, but circumstances often arise that
create a positive or negative pressure in a space. Typically, a building
should maintain a slightly positive pressure, +0.01
inches’
water
column. 75F solutions can regulate the pressure differential when the
Pressure Sensor Package Solution is used in conjunction with a 75F®
Outside Air Optimization
™
Package.

PRECAUTIONS
•
Failure to wire devices with the correct polarity when using a
shared transformer may result in damage to any device
powered by the shared transformer.
•
Do NOT mount the tubing so that the inside or outside tube
ends are in direct line of a breeze or draft.
•
Remove power before wiring. Never connect or disconnect
wiring with the power applied. Do not allow live wires to
touch the circuit boards.
