How the Smart Bypass Damper Works:
The Ultra-Zone Smart Bypass Damper captures
(with the push of a button) the total static
pressure of the HVAC system during non-zoned
mode, and modulates to maintain that same static
pressure value, during zoned mode. As individual
zone dampers open or close, the HVAC system static
pressure will fluctuate. In order to maintain the true
static pressure of the HVAC duct system during zoned
HVAC operations, a bypass duct with a reliable bypass
damper and a smart motor actuator must be installed.
No other bypass damper is easier to setup, than the
Ultra-Zone Smart Bypass Damper.
Description of the SBD Motor Actuator:
The Smart Bypass Motor Actuator is a digital
differential pressure controller with an integrated PI
loop and intelligent software. The Smart Bypass
Damper is the only industry bypass solution that
can automatically measure, monitor and maintain
the designed operating static pressure of the
HVAC system in all modes of operation.
The Smart Bypass Damper includes all of the
accessories needed for field installation.
No measuring instruments are required.
