This manual provides instructions for operating the RH100, RH400 and RH900 digital temperature controllers. It explains the RUN/STOP switching, automatic calculation (AT), start‑up calculation (ST) and other functional settings.
The document also includes safety notes, parameter configuration, mode display options and environmental compliance information for the controllers. This manual is written in Chinese.
AT is started by selecting the AT function; it stops automatically when certain conditions are met, such as reaching temperature limits or after a timeout.
ST calculates and sets PID constants automatically when power is applied or when switching from STOP to RUN, helping the controller respond quickly.
