Smart HVAC Control with Integrated Slave Actuator

The slave actuator unit controls a fan or HVAC system in a specific room or section of a home or building by executing commands from the master actuator. It manages various fan controls, including the RPM of a brushless DC (BLDC) fan motor, airflow direction (in/out and optionally up/down, left/right), flow sensor measurements (liters per minute), and electrical heater settings from 0% to 100%. When controlling an HVAC system, the actuator may incorporate additional sensors and outputs for enhanced control, such as the RPM of a BLDC compressor motor and a compressor pressure sensor. A user interface, through capacitive touch, push buttons, or an LCD, displays local values and allows data entry. A more advanced GUI can be accessed via a master actuator, IP gateway, or smartphone. A real-time clock (RTC) can be integrated to switch between operation modes based on the day, time, or holidays, with synchronization across the system.

System Benefits​:

• Bluetooth^® 5 Mesh communication enables secure bi-directional packet data flow with other sensors and actuators.
• Operates with low power consumption, achieving microampere-level averages while maintaining connectivity.
• Eliminates the need for additional wiring, simplifying installation and reducing costs.
• Features automatic routing without the need for setup, enhancing ease of use.
• Offers scalable speed versus range, providing flexibility for extended range or increased speed depending on location.
• Supports power supply options from building control systems, including 230V_AC, 110V_AC, or 24V_DC.
