Frequently Asked Questions
Q: What size damper is included in the SACG2K-04 kit?
A: This kit includes a 4" stainless steel motorized damper suitable for standard ducting applications.
Q: Can I use this with multi-speed fans?
A: Yes, but fans should be set to a single-speed mode when using the FanConnect™ switch.
Q: What’s the difference between Calculated Flow and Calculated Time setup?
A: Calculated Flow uses CFM data to determine runtime, while Calculated Time sets runtime in minutes per hour manually.
Q: Is the system UL listed?
A: Yes, all components are evaluated by UL and cUL to meet safety requirements:contentReference[oaicite:0]{index=0}.
Q: How do I wire the controller?
A: Refer to the included wiring diagram; ensure the controller is powered with 24VAC and the G wire is correctly interrupted:contentReference[oaicite:1]{index=1}.
Q: Is the damper position critical for airflow?
A: While the damper can be installed in any position, horizontal mounting with the motor at 12 o’clock is recommended for reliability:contentReference[oaicite:2]{index=2}.
