The RLU2 universal controller is used to process control variables such as temperature, relative/absolute humidity, pressure/pressure difference, airflow, indoor air quality and enthalpy. The controller offers pre-set standard applications and can be freely programmed to suit specific model requirements. It provides P-, PI, or PID modes and supports menu-driven operation.
The Siemens universal controllers (RLU210, RLU222, RLU232, RLU236) are designed for ventilation, air‑conditioning and indoor climate equipment. They support temperature, humidity, pressure, airflow and air‑quality control in comfort, economy and protection modes.
The manual provides detailed information on mechanical design, electrical connections, input/output configuration, safety requirements, and technical specifications, along with ordering and part information for each model. This manual is written in Chinese.
