Testing for Attic Depressurization

The Breeze Mate™ solar ventilation system features ourproprietary differential pressure sensing technologydesigned to prevent attic depressurization. When an atticspace has insufficient intake ventilation, depressurization ofthe attic may occur resulting in decreased energy efficiencyand poor performance from your solar attic fan. BreezeMate™ gives you the control to ensure that your solar atticfan is properly installed and operating at maximum air flowperformance.

Access the Depressurization Test Menu by holdingdown the Decrease Button [4] for 10 seconds.

Depressurization Testing (continued)

At the end of the equilibrium period, the BreezeMate™ control system will collect pressure data toestablish a barometric pressure baseline. After thisdata is collected, the control system then starts all fansinstalled on the network, allowing the fans to operatefor a period of five minutes.

►

Expect slight changes in the ambient barometricpressure readings, even when your solar attic fanis not operating. Due to the extreme sensitivitydesigned into our pressure sensing technology,normal variations in the barometric pressure will beobserved during testing. For this reason, Attic Breezerecommends performing the Depressurization Testduring clear and sunny weather conditions to minimizeinterference from changes in barometric pressure.

!

At the end of this period, the control system onceagain collects pressure data. The values recorded forattic pressure, both during fan operation and without,are compared to determine the amount of atticdepressurization present. The result is then evaluatedto determine the final status of the test.

►

-17-

If your solar attic fan installation passes theDepressurization Test, the controller will exit the testprogram after 10 seconds and return to the maindisplay screen. A “passed” test indicates that yourattic has the proper amount of intake ventilation tosupport your ventilation system.

►

Please note that the Breeze Mate™ control systemdefaults to automatic mode off upon exit of theDepressurization Test. Automatic control must beturned on after testing to resume temperature andhumidity control.

!

If your solar attic fan installation does not pass theDepressurization Test, the Fan Icon [2] will beginblinking and the controller will remain in alarm modeuntil the depressurization alarm is acknowledged. Thedepressurization alarm may be acknowledged bypressing the On/Off Button [8]. A “failed” test indicatesthat your attic may not have the proper amount ofintake ventilation to support your ventilation system.

►

If your installation fails the Depressurization Test,check the following:

Run the test again to confirm the results.Changes in barometric pressure may effecttesting, resulting in a “borderline” test failure.

Verify that the Depressurization AlarmThreshold [27] value is set properly. If thealarm is set too low, atmospheric pressureinterference may adversely effect testing.

Make sure your soffits and other air intakevents are clear of debris and obstructions.

If needed, repeat the test using the nexthighest Depressurization Alarm Threshold [27]setting. A “passed” test at higher settings mayindicate the need for more air intake ventilation.
