Product Description Product DescriptionThe HL2023 Series from Hailin is a sophisticated and versatile thermostat designed for superior temperature management in industrial, commercial, and residential applications. Perfect for retrofit projects in offices, apartments, and hotels, it seamlessly integrates with DC brushless fan coil units and valve systems to provide efficient and comfortable climate control.Key Features & Benefits:Crystal-Clear LCD Display: A large, easy-to-read screen with white backlight clearly displays all vital information, including indoor temperature, set temperature, operating mode, fan speed, and valve status.Flexible Control Modes: Choose from Cooling, Heating, or Fan-Only modes to match your comfort needs precisely.Intelligent Fan Speed Control: Manually select from five speeds (Ultra-Low, Low, Medium, High, Ultra-High) or set it to Auto. In Auto mode, the built-in PID algorithm intelligently adjusts the fan speed based on the real-time temperature difference for optimal efficiency and comfort.Advanced Valve Control Options: The series offers models for various systems:HL2023DA2/DB2 (2-Pipe): For on/off control of electric valves with different shutdown sequences.HL2023FCV2 (4-Pipe): Independently controls hot and cold water valves for 4-pipe fan coil systems.HL2023-DF: Features a 0-10V output for precise control of DC inverter fans.Frost Protection: Automatically activates the heating system if the room temperature drops below a predefined threshold (e.g., 5°C), protecting your space and plumbing from freezing temperatures.Energy Saving Programming (T74 - Optional): Maximize energy efficiency with 7-day, 4-period programming, allowing you to set different temperature schedules for weekdays and weekends.Built-in Time Clock & Timer: Schedule daily on/off times to ensure comfort when needed and save energy when spaces are unoccupied.Dry Contact Input: Supports integration with external systems like door cards or building management systems (BMS) for centralized control, enabling functions like forced shutdown or energy-saving mode activation.User-Friendly Design: Features intuitive tactile buttons and a sleek, modern design that complements any interior. The standard 86x86mm size ensures easy replacement and installation.Technical Specifications:Power Supply: AC 85-250V, 50/60HzLoad Capacity: <2A (Resistive), <1A (Inductive)Temperature Setting Range: 5°C - 35°CSetpoint Resolution: 0.5°CDisplay Accuracy: ±1°CInstallation: Standard 60mm wall box mountingIngress Protection: IP30
