OT-ZW8002 Intelligent Temperature Controller

The temperature and humidity controller integrates multiple advanced technologies, including microprocessing, sensor technology, and computer-based control. It uses imported high‑precision temperature and humidity sensors to measure environmental conditions, with a high‑brightness LED display and comprehensive control logic based on operating status.
The device is designed for temperature and humidity monitoring and regulation, suitable for terminal boxes, high‑ and low‑voltage switchgear, transformers, box‑type substations, circuit breakers, and similar equipment requiring moisture protection, low‑temperature heating, and high‑temperature ventilation.
It provides automatic heating under low‑temperature conditions and automatic ventilation under high‑temperature conditions.
