The LY-WSK-ZA is a professional intelligent temperature and humidity controller designed exclusively for the power industry and precision environments. It adopts PID control and fuzzy logic algorithms to maintain stable environmental conditions, supporting dual sensors for redundancy and real-time monitoring via local LCD and remote platforms. With a compact design (48mm×48mm×78mm) and robust load control (3A per channel), it ensures equipment reliability in critical settings like substations and data centers.

Precision Control Algorithms: Combines PID control and fuzzy logic to minimize temperature/humidity deviations (temperature: ±0.5℃; humidity: ±5%RH).
Dual-Sensor Redundancy: Equips Sensor 1 and Sensor 2 to avoid data loss if one sensor fails, enhancing system reliability.
Remote Monitoring & Control: Enables real-time data access and parameter adjustment via electronic interface or mobile App, improving operational flexibility.
Configurable Alarm System: Triggers alerts for temperature/humidity deviations, load faults, or sensor errors, ensuring timely intervention.
Energy Efficiency: Optimizes load operation (e.g., heaters, dehumidifiers) to reduce energy waste while maintaining set conditions.
Wide Environmental Adaptability: Operates in -20℃~+70℃ and ≤95%RH (no condensation), suitable for harsh industrial sites.
Seamless Integration: Supports Modbus RTU protocol, easily connecting to existing automation systems (e.g., SCADA in power plants).
The LY-WSK-ZA features a stable AC 220V power supply, dual 3A load channels, and low power consumption (<2W). Its control range (temperature: -9℃~99℃; humidity: 099%RH) and adjustable backlash (020℃/0~20%RH) meet diverse precision needs.

The LY-WSK-ZA is essential for environments requiring strict temperature and humidity control:
Power Plants: Regulating temperature/humidity in control rooms and equipment enclosures to prevent component corrosion.
Transformer Stations: Maintaining dry conditions to avoid insulation damage in high-voltage transformers.
Data Centers: Protecting servers and storage devices from overheating or moisture-related failures.
Precision Manufacturing: Ensuring stable environments for semiconductor or pharmaceutical production lines.
Laboratories: Supporting consistent conditions for scientific experiments (e.g., environmental testing labs).
Evaluate Operating Environment: Confirm the site temperature (-20~70℃) and humidity (≤95%RH) match the controller’s specs.
Check Load Requirements: Select based on load current (≤3A per channel) and number of loads (single/dual channels).
Verify Communication Needs: Choose Modbus RTU compatibility if integrating with remote automation systems.
Sensor Redundancy: Opt for dual sensors for critical applications (e.g., substation transformers) to avoid downtime.
Alarm Functionality: Ensure configurable alerts align with site needs (e.g., email/SMS notifications for remote sites).
Installation: Wire AC 220V (L/N) to the controller; mount Sensor 1 and Sensor 2 at representative positions (avoid direct sunlight/airflow).
Parameter Configuration: Use the front-panel buttons to set target temperature/humidity, backlash, and alarm thresholds (e.g., 25℃±2℃, 50%RH±5%).
Real-Time Monitoring: View current conditions, load status, and alarms via the 8-digit LCD display; check remotely via App/interface.
Maintenance: Calibrate sensors quarterly; clean the controller surface and check wiring connections annually to prevent loose contacts.
