Sanda BTZ-S500(2W2S) Intelligent Temperature and Humidity Controller is a temperature and humidity controller with 1 fan and 1 heater. It can be separately set with upper and lower limits of temperature and humidity. When the environmental temperature and humidity exceed the set range, the fan or heater will be automatically started.
The BTZ‑S500 is an intelligent temperature and humidity controller with a 4‑digit LED display. It measures temperature from 0 °C to 99 °C and humidity from 0 % to 99 % RH, and can control a fan and a heater based on programmable upper and lower limits. The device includes power input, relay outputs, and RS‑485 communication.
The manual explains the basic functions, technical specifications, operation principles, panel operation, installation, wiring diagrams, and communication address settings. It also describes the anti‑interference system, self‑check on power‑up, and how to set temperature and humidity limits using the keys on the front panel. This manual is written in Chinese.
