The Ultra-Zone™ smart by-pass damper (SBD) captures the total static pressure of the HVAC system during a non-zoned mode and modulates to maintain that same static pressure during any zoned mode. As individual zone dampers open and close, the HVAC system static will fluctuate. In order to maintain the true static pressure of the HVAC system during zoned modes, the SBD will sense the current static pressure in the duct system and modulate to maintain the designed operating static pressure of the HVAC system. Upon power up, the SBD's power LED will glow solid green. The yellow by-pass set up button LED will blink, to indicate the SBD is ready for start up. With the simple push of the yellow by-pass set up button located on the SBD motor, the damper will fully close and measure the system's total static pressure. The SBD will then open and measure the system's total static pressure. The by-pass set up LED will stop blinking and go out. The by-pass damper is now set, you're done! with our new NFC function, using your android smartphone will allow you to access the SBD and adjust the static, if needed or view the static pressure value, system static set points, the damper position, hours of operation and indoor fan activity. Our ZIP-BT-NFC (bluetooth adapter) will allow any iOS smartphone to control and access the SBD as well. The SBD's unique curved blade design provides the required pressure drop baffling within the duct system for improved by-pass control and increased linear response by the actuator. The smart by-pass damper can be mounted in any direction, horizontally, vertically or any position required in the field. The supplied pitot tubes should be mounted within 2 ft of the air handler of the supply and return plenums. The SBD is the only by-pass damper that will meet and exceed all requirements of the residential zoning standard in ACCA manual Zr. The smart by-pass damper is the only damper that will satisfy all your needs and requirements in one design. No measuring instruments are required. No weights to adjust. No springs to crank. The SBD is ACCA manual ZR compliant. As an added benefits of the unique blade design and the smart, self-balancing feature of the SBD, there is no need to install and setup a separate bypass balancing hand damper.
