Frequently Asked Questions
Do I need an Expansion Board with my Affinity Controller?
Most homeowners do not require an Expansion Board. It is only needed when Ethernet connectivity or 0–10V integration with a building management or home automation system is required. The Expansion Board is an optional accessory for 1 Channel and 2 Channel controllers and is built into 5 Channel controllers.
What does the Expansion Board do?
The Expansion Board adds Ethernet connectivity and 0–10V integration capabilities to compatible Bromic Affinity controllers, allowing them to communicate with supported home automation and building management systems.
How is the Expansion Board installed?
The Expansion Board is designed specifically for Bromic Affinity controllers and mounts directly inside the controller enclosure using the supplied hardware.
Does the Expansion Board require its own power source?
No. The Expansion Board receives power directly from the Affinity controller and does not require a separate electrical connection.
Can I use the Bromic Smart-Heat® App with the Expansion Board?
When configured for 0–10V building management system control, app functionality is disabled and the connected automation system becomes the primary method of operation.
Is the Expansion Board compatible with home automation systems?
Yes. The Expansion Board accepts a standard 0–10V control signal, making it compatible with many home automation and commercial building management platforms.
