Energy Recovery for Residential and Commercial HVAC Systems with Intelligent Control and Wifi Function
Forced Fresh Air + Energy Recovery + Intelligent Control + Wifi Function
Product Overview
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
Product Features
Basic Functions
Equipment Operation Modes:
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
Additional Basic Features:
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
Advanced Functions
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
Preset Functions
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)
Multiple signal interfaces including RS485, bypass control, and alarm signals
