No, neither the Affinity On/Off Controller nor the Dimmer Controller is required for the patio heater to function. The unit can be hardwired and operated using a standard wall switch. However, both controllers are highly recommended for enhanced convenience and functionality.
The On/Off Controller allows wireless control via the Bromic app, scheduling, and multi-zone heater management. The Dimmer Controller (for electric models only) adds precision control over heat output in 1% increments. Both controllers support voice commands and app integration for smart home setups.
