is part of a broader series (including MC401, MC701, MC901) that shares similar, user-friendly functionality. Key features include:
Hold the (or SET + <) keys for 3 seconds to enter the menu. Use the arrows to find the "Unit" parameter. Change the value from 000 (Celsius) to 001 (Fahrenheit). Hold the MODE key for 3 seconds to exit and save. Entering PID Auto-Tuning:
For detailed visual schematics and advanced parameter explanations, refer to the official Sinotimer MC-101 manual.
If your system experiences temperature overshoot or stabilizes too slowly, run the automatic PID tuning sequence. sinotimer mc101 manual
This is the most critical part of the . The device has 10 hidden functions.
Connect power to the controller and the sensor (thermocouple) to the designated terminals. Ensure the output (SSR or Relay) is correctly wired to the heating/cooling element. Setting Target Temperature: arrows on the front panel to adjust the SV (Set Value). Accessing Menus:
| Terminal(s) | Function | Description & Wiring Notes | | :--- | :--- | :--- | | | Power Supply | Connect to 85-265V AC, 50/60Hz power source. Ensure correct voltage. | | 3, 4, 5 | Relay Output | - 3: Normally Open (NO) - 4: Common (COM) - 5: Normally Closed (NC) | | 6 & 7 | Alarm Output | Connect an external alarm device (e.g., buzzer, light) to these terminals. | | 8, 9, 10 | Sensor Input | - For RTD (Pt100): Connect 'A' to Terminal 8, 'B' to Terminal 9. - For Thermocouple (TC): Connect the negative (B-) lead to Terminal 9, and the positive (A+) lead to Terminal 10. | | 11 & 12 | SSR Output | Connect to the DC input of an external Solid-State Relay (SSR). Terminal 11 is SSR+, Terminal 12 is SSR-. | is part of a broader series (including MC401,
Run the Auto-Tuning (AT) procedure again.
For a seasoned electrician or controls engineer, the MC101 manual is a familiar roadmap. They skip the safety warnings, turn to the terminal diagram, wire by feel, and then interpret the function switch table. The main challenge is the semi-ambiguous naming of modes: What Sinotimer calls “Interval” might be called “One-shot” elsewhere. The manual mitigates this with timing diagrams that transcend language.
This provides a dry relay contact for external buzzers, indicator lights, or safety shutoffs. 3. Button Functions and Interface Navigation This is the most critical part of the
| Mode | Name | How it works | | :--- | :--- | :--- | | | Signal Delay | Power on -> Relay waits -> Turns on -> Stays on. | | P-2 | One-shot (Edge trigger) | Power on -> Relay turns on -> Runs for set time -> Turns off. | | P-3 | Cyclic (Start ON) | Power on -> Relay ON for time 1 -> OFF for time 2 -> Repeats. | | P-4 | Cyclic (Start OFF) | Power on -> Relay OFF for time 1 -> ON for time 2 -> Repeats. | | P-5 | Signal Hold (Latch) | A trigger signal toggles the relay ON/OFF (like a light switch). |

This is the most common operation.
Even with the , things can go wrong. Here are the top 5 issues and fixes.
Before you begin, . Ensure all wiring is performed by a qualified electrician and complies with local electrical codes. Always disconnect power before making any connections.
