Supports RS485 protocol central fresh air units and wall-mounted fresh air units, controlling three-speed fan operation, heat exchange start/stop, internal/external circulation switching, and filter replacement reminders.
Core Functions
Supports RS485 protocol central fresh air units and wall-mounted fresh air units, controlling three-speed fan operation, heat exchange start/stop, internal/external circulation switching, and filter replacement reminders.
Sensor Linkage: Can link with indoor temperature and humidity sensors and CO2 concentration sensors, automatically increasing the fresh air ventilation level when air quality is poor.
Application Scenarios
High-End Fully Furnished Residential: Integrated intelligent control of whole-house central air conditioning, hydronic floor heating, and central fresh air, with mobile remote pre-start for heating or air conditioning.
Hotels, Apartments, and Homestays: Centralized guest-room temperature control, automatic power-off when guests leave, and household energy metering to reduce operating electricity costs.
Office Buildings, Shopping Malls, and Industrial Parks: Central air-conditioning household metering, scheduled zone start/stop, and BMS building system integration for energy-saving operation and maintenance.
Existing Home HVAC Intelligent Retrofit: Direct replacement of old wired controllers without changing existing pipelines, enabling rapid access to a whole-house intelligent system.
