BYPASS DAMPER with INTEGRATED PRESSURE CONTROL (Part # STBP or STCDBP) Bypass Damper with Integrated Pressure Control is used to control bypass operations. The bypass damper modulates to maintain static pressure as zone dampers open and close. The bypass system reduces air noise from the supply registers caused by excessive air velocity. - Page 33 Y outputs to unit on the zone control board and to make full cool calls on all thermostats.
