Frequently Asked Questions
Q: What is the duct size supported by the SACG2K-08 model?
A: The SACG2K-08 kit includes an 8" stainless steel damper, ideal for high airflow residential systems.
Q: How does the controller determine fan run time?
A: It uses a patented algorithm in either Calculated Flow or Calculated Time mode based on measured airflow and ASHRAE standards:contentReference[oaicite:0]{index=0}.
Q: What happens if the exhaust fan runs longer than needed?
A: The system will indicate an error via the blinking EXH icon if the FanConnect™ switch exceeds 4 hours:contentReference[oaicite:1]{index=1}.
Q: Can the damper be installed vertically?
A: Yes, it can be installed in any position, but horizontal with the motor at 12 o'clock is recommended for optimal reliability:contentReference[oaicite:2]{index=2}.
Q: Is the system safe for bathroom exhaust fan use?
A: Yes, the FanConnect™ switch can control both fan and light, rated up to 150W fan and 450W light load:contentReference[oaicite:3]{index=3}.
Q: Does the controller need a common (C) wire?
A: Yes, the AirCycler® g2 controller requires a 24VAC common connection for power:contentReference[oaicite:4]{index=4}.
