Always disconnect power before wiring the device. Check the diagram printed on your specific unit, as terminal layouts can vary.
Ensure your sensor and heater are placed in their final working positions. Set your desired target temperature (). Long-press SET for 3 seconds to open the menu. Cycle through the menu until you locate the AT parameter. Change the value from 0 (Off) to 1 (On). Press SET to exit and launch the automated tuning routine. The AT light will flash continuously on the front panel. Wait for the system to cycle through 2–3 heating peaks.
If you'd like to dive deeper into a specific part of the setup, let me know: Are you trying to or the power supply ?
This guide provides the necessary steps to get your working. For more specific applications, always refer to the wiring label attached to your specific unit.

Press to access configuration menus and save parameter changes.
To enter the advanced setup menu, press and hold the button for 3 seconds. Use the Up/Down keys to change values, and press SET to advance to the next parameter.

Verify that your SSR is not stuck "on" and that your output settings in the menu are correctly configured for your device. Where to Buy & Resources
Offset value to calibrate sensor reading errors. If the PV reads 2°C too high, set SC to -2.0 . 5. How to Run Auto-Tuning
Sinotimer devices are built to resist dust and moisture, but they should still be housed in a proper enclosure for longevity in harsh environments. Temperature Controller - Sinotimer

35mm DIN Rail or Panel Mount (depending on casing style). 2. Key Interface and Button Functions
Fix: The measured temperature has dropped below the lower limit of the chosen sensor type, or the polarity (+ and - wires) of your thermocouple is reversed. System Internal Data Error.
The Sinotimer MC101 is a versatile digital timer that allows users to set timing intervals, countdowns, and schedules. Its user-friendly interface and compact design make it suitable for a wide range of applications.
To enter the parameter menu, hold the button for 3-5 seconds. Use SET to switch between parameters and arrows to change values.
