Low Temperature Air-Cooled Heat Pump Inverter Controller
Features
Designed for 3–10 HP inverter low-temperature enthalpy-boost heat pump units, this solution is compatible with a wide range of DC compressors available on the market. It supports flexible modular combinations of 1 to 8 units, features EXV throttling and EVI enthalpy enhancement, and allows free configuration of single or dual DC condenser fans. Modbus centralized control protocol is supported.
It can be paired with an LCD dot-matrix display with capacitive touch keys, or an optional 4-inch color touch screen for more intuitive operation.
Air-Cooled Inverter Chiller/Heat Pump 3-in-1 Integrated Unit Controller
Features
This solution is suitable for low-temperature air-source heat pump systems that integrate air conditioning, floor heating, solar heating, boilers, and domestic hot water. The main control is divided into indoor and outdoor units, with a split driver design. The wired controller can be equipped with an LCD text display for enhanced industrial-grade reliability, or an optional 4 inch color touch screen for more intuitive operation.
Low-Temperature EVI Air-Cooled Cabinet Unit Controller
Features
Suitable for split indoor–outdoor direct expansion systems with 1–4 circuits and fixed-frequency operation. The condenser can share airflow or operate with independent fans and supports 0–10V condenser speed control. Features include EXV throttling, EVI enthalpy enhancement, and optional single-speed or three-speed supply fans. Standard Modbus centralized control protocol is supported.
Available with three types of touch-screen displays:
Low-Temperature EVI Air-Cooled Chilled/Hot Water Modular Unit Controller
Features
Low-temperature air-cooled modular units support free combination of 1 to 16 modules, with each unit allowing 1–4 system configurations. EXV, EVI control NTC, pressure sensor, compressor current transformer are optional
Available with two types of displays:
Air-Cooled / Water-Cooled (Heat Pump) Combo Controller
Features
Air-source/water-source cooling and heating air system controller, supporting standard operation mode, fresh-air operation mode, and optional configurations including heat pump, cooling-only, or cooling + electric heating models.
Equipped with an 86×86 mm wall-mounted display panel featuring DC 12V power supply, RS485 communication, capacitive touch keys, and a neutral interface design for simple, user-friendly operation.
Inverter Direct Expansion (DX) Unit Controller
Features
Split-type indoor–outdoor dual-system direct expansion (DX) units. Supports dual inverter compressors, fixed-speed + inverter compressor combinations, dual DC condenser fans, dual AC condenser fans, two-stage electric heating, dual EXV throttling, DC variable-speed indoor blowers, and AC single speed/three-speed indoor blowers.
All system configurations can be freely matched through indoor/outdoor DIP switch settings. Module-combination functionality and OTA remote management capability are reserved.
Fan Driver Board Controller
Features
The fan driver uses a sensorless FOC (Field-Oriented Control) algorithm to drive the motor and adopts a discrete-component hardware design. It includes PFC and power filtering. Motor control options include 0–10V (reserved), three-speed control, or RS-485 communication.
