Product Description
Residential ERV HRV Equipment
Engineered to optimize indoor air exchange and reduce energy waste in residential buildings
Intelligent Electrical Control Features
Basic Hardware
- 1 fresh air inlet temperature sensor
- 1 supply air outlet temperature sensor
- 1 return air temperature sensor
Optional Hardware
- 1 external humidity sensor
- 1 external CO2 sensor
- 1 external differential pressure switch
- 1 WiFi module
Customer-Supplied Hardware
- 2 external electric heaters
Hardware Interfaces Reserved for Customer
- 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
Functions Available with Standard Keypad Controller (HDK-CK23C2)
Basic Functions
- 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
Engineering Mode
- Allows free adjustment of fan speeds for supply and exhaust air at each speed level
Advanced Functions
- 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
Pre-configured Functions
- 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
Functions with Optional Keypad Controller (HDK-CK23C3)
Basic Functions
- 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
Advanced Function
- Ultra-Low Temperature Operation: Unit can operate normally (intermittently) even below 5°F (-15°C)
Pre-configured Functions
- 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
Note: Controller products are classified into Level 1 and Level 2 based on functionality. The keypad controller HDK-CK23C3 is a Level 2 controller. The keypad controller HDK-CK23C2 and the intelligent fresh air controller HDK-CK23C1 are both Level 1 controllers. Compatibility rules: A Level 2 controller can coexist with either of the two Level 1 controllers without conflict. However, the two Level 1 controllers cannot be used simultaneously; only one must be selected.
