Do I Have to Connect Units to All Ports on a DIY Multi-Zone System?

No, it is not required to connect units to every port on a DIY Multi-Zone system. However, it is essential to connect at least two-thirds of the system's maximum BTU capacity to ensure proper operation. This prevents potential errors or damage to the system.

Key Points to Consider:

• Connect at least two-thirds of the maximum BTU capacity.
• Avoid overloading or underloading the system.
• Follow the specific requirements of your unit for optimal performance.
