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.
