Air Temperature Sensor And Residential ERV HRV equipment engineered to optimize indoor air exchange and reduce energy waste in residential buildings

Engineered to optimize indoor air exchange and reduce energy waste in residential buildings with intelligent electrical control features.

• 1 fresh air inlet temperature sensor
• 1 supply air outlet temperature sensor
• 1 return air temperature sensor

• 1 external humidity sensor
• 1 external CO2 sensor
• 1 external differential pressure switch
• 1 WiFi module

• 2 external electric heaters

• 2 RS485 communication ports: 1 for centralized control to external system, 1 for communication between master and slave boards
• 4 digital inputs reserved: Fire alarm signal input, bypass control switch, forced start switch, differential pressure signal input, forced high-speed signal input
• 4 digital outputs reserved: Operation status signal output, fault signal output, electric heater 1 output, electric heater 2 output

• Heat Exchange Mode: Energy from exhaust air can be extracted to heat (in winter) or cool (in summer) the fresh air, reducing energy consumption
• Speed Adjustment: 5 adjustable speeds (positions 1, 3, 5, 7, 10) for supply air and exhaust air outlets, adjustable independently
• Operation Timer: Unit can operate intermittently for 15min, 30min, or 45min per hour; continuous operation also possible
• Power-off Memory: Unit retains its operating status prior to power outage upon restart
• Frost Protection: Unit enters frost protection mode when outdoor temperature is too low

• Allows free adjustment of fan speeds for supply and exhaust air at each speed level

• Ultra-Low Temperature Operation: Can operate normally (intermittently) even below 5°F (-15°C)
• Temperature Calibration: Displays and calibrates 3 air temperatures (fresh air, return air, supply air); all 3 temperatures used in intelligent control
• Advanced Sleep Mode: Operates at lowest speed during specific periods, intelligently opens or closes bypass based on indoor-outdoor temperature difference to reduce air conditioning energy consumption
• Intelligent Airflow Compensation: Intelligently compensates airflow after prolonged operation without replacing or cleaning filters or the core

• Cloud Control: Remote control via Tuya Cloud platform mobile APP (WiFi module required)
• Forced Dehumidification: Set desired indoor humidity for intelligent operation (humidity sensor required)
• CO2 Forced Ventilation: Intelligent operation based on preset CO2 control logic (CO2 sensor required)
• Differential Pressure Filter Alert: Intelligent operation and alerts based on core and filter differential pressure (differential pressure switch required, must be installed at factory)
• Multiple Signal Interfaces: RS485 interface, bypass control switch signal, differential pressure signal, forced start/stop signal, fire alarm signal, forced high-speed input signal, fault signal, operation signal, and electric heating signal

• Heat Exchange Mode: Energy from exhaust air can be extracted to heat (in winter) or cool (in summer) the fresh air, reducing energy consumption
• Speed Adjustment: One-touch high speed for supply/exhaust air and one-touch exit from high speed mode
• Operation Timer: One-touch high speed duration: 10/20/30 minutes
• Power-off Memory: Unit retains its operating status prior to power outage upon restart
• Frost Protection: Unit enters frost protection mode when outdoor temperature is too low

• Ultra-Low Temperature Operation: Unit can operate normally (intermittently) even below 5°F (-15°C)

• Multiple Signal Interfaces: RS485 interface, bypass control switch signal, differential pressure signal, forced start/stop signal, fire alarm signal, forced high-speed input signal, fault signal, operation signal, and electric heating signal
