FAQ

Yes. Our universal controller supports up to 3 Heat / 2 Cool stages, making it fully compatible with conventional systems, Heat Pumps, and Dual-Fuel (Hybrid) setups. It’s designed to be the versatile "brain" for 95% of North American HVAC equipment.

Absolutely. This is a brand-neutral panel. It works seamlessly with any standard 24VAC thermostat, allowing you to offer customers their favorite smart home interface while maintaining robust zoning logic.

Our wireless option eliminates the need to run new thermostat wires through finished walls. By using a high-penetration RF signal, you can add zones in multi-story homes in a fraction of the time, significantly reducing labor costs.

We’ve implemented Push-In Terminals for all connections. No screwdrivers are required, which speeds up wiring by 50% and ensures a secure, vibration-proof connection that reduces future service calls.

Yes. The panel features integrated Discharge Air Temperature (DAT) sensor logic and anti-short cycle timers. These safeguards prevent the coil from freezing or the heat pump from overheating, extending the lifespan of the HVAC equipment.

Yes. Our controllers are scalable. You can easily configure the panel to manage 2, 3, or 4 zones, allowing you to stock one SKU for multiple residential layouts.

We offer direct access to our R&D engineering team for complex integration queries, along with detailed wiring diagrams and a dedicated technical hotline to ensure your project is completed without downtime.

The panel features intelligent dual-fuel logic. It automatically manages the transition between the heat pump and the auxiliary heat source based on efficiency or temperature setpoints, ensuring optimal comfort and energy savings.
