Energy Recovery for Residential and Commercial HVAC Systems with Intelligent Control and Wifi Function for Residential ERV HRV And Total Heat Exchanger

The CFA series fresh air ventilator is a comprehensive ventilation device that integrates air purification and energy recovery. It consists of a heat exchanger, filters, plastic-encapsulated DC fans, and other components, delivering three primary functions:

• Fresh Air Ventilation: Continuously delivers treated fresh air indoors while exhausting stale indoor air to improve indoor air quality
• Air Purification: Outdoor air is purified by filters before being supplied indoors, enhancing indoor air quality
• Energy Recovery: The total heat exchanger extracts energy from exhaust air to heat (in winter) or cool (in summer) incoming fresh air, reducing energy consumption

• Heat Exchange Mode: Recovers energy from exhaust air to heat or cool incoming fresh air
• Bypass Mode: Introduces outdoor air directly indoors without heat exchange when temperature is suitable
• Automatic Operation Mode: Operates according to preset fan speed levels with optional auto-bypass
• Sleep Mode: Low-speed operation with screen off during sleep periods

• 10-level speed adjustment with user-configurable air volume
• Positive/Negative pressure adjustment with separate fan speed control
• Screen lock functionality
• Scheduled on/off operation
• Weekly timer for different operating statuses
• Filter and heat exchanger maintenance reminders
• Power-off memory function
• Fault display with error codes
• Smart bypass based on temperature conditions
• Frost protection for low outdoor temperatures
• Engineering mode for advanced fan speed adjustment

• Ultra-low temperature operation (intermittent operation below -15℃)
• Temperature calibration for three air inlets/outlets
• Advanced sleep mode with intelligent bypass control
• Intelligent air volume compensation for long-term operation

• Cloud control via Tuya Cloud Platform mobile app (requires Wi-Fi module)
• Forced dehumidification with target humidity control (requires humidity sensor)
• CO2 forced exhaust based on preset control logic (requires CO2 sensor)
• Differential pressure controlled filter reminders (requires differential pressure switch)
• Multiple signal interfaces including RS485, bypass control, and alarm signals
