Shifts the active editing digit to the left for fast data entry. Up / Down Arrows: Increases or decreases numerical values. 4. Advanced Parameter Configuration
Normally Open (NO) relay contact for Alarm 1. This can trigger an external buzzer, light, or safety contactor. 3. Button Layout and Basic Navigation The front panel consists of four control keys:
Getting the wiring right is the first step to a safe setup. Use a wiring diagram
The MC101 supports two primary styles of temperature control. Method A: Auto-Tuned PID Control (Recommended)

Connect a bridge wire from Terminal 1 (Live) to Terminal 3 (COM) if you want to output the same voltage. If you are switching a different circuit (e.g., a 12V valve using a 220V timer), connect the external power source to Terminal 3.
While this article covers everything, you can find the official laminated Sinotimer MC101 manual in PDF format on most electrical wholesaler websites or by scanning the QR code on the original packaging.
Decreases the target temperature or parameter value.
The SINOTIMER MC101 is a versatile digital display PID (Proportional-Integral-Derivative) temperature controller. Think of it as the intelligent brain for your heating or cooling system. It processes temperature data from a sensor (like a thermocouple or RTD) and precisely controls a heating element or cooling device to maintain a target temperature. Its primary uses include: Shifts the active editing digit to the left
Before installation, verify that the technical specifications of your specific MC101 variant match your electrical system requirements.
Dual 4-digit LED (Red for Process Value, Green for Set Value) Supported Sensor Inputs (Universal)
Note: To exit the setup menu at any time, hold the button down again for 3 seconds, or wait 30 seconds for the device to automatically time out. 6. Utilizing the Auto-Tuning Feature
If the controller reads "EEEE" or an impossible temperature, go into the settings (Cod=0000) and ensure the input type matches your sensor (e.g., set to "K" for K-type). Celsius vs. Fahrenheit: Button Layout and Basic Navigation The front panel
Press to enter parameter menus, save modified values, or switch between setting loops.
Master Your Temperature Control: The Ultimate Sinotimer MC101 Guide
: Features dual-integrated options allowing users to leverage either the built-in mechanical relay (typically rated up to 2A/250V AC resistive loads) or a Solid-State Relay (SSR) voltage output (typically 12V DC pulse). Panel Display Reference & Key Operations
It is recommended to run the auto-tune function upon first use to allow the device to "learn" the thermal lag of your specific setup. Safety & Maintenance Heat Dissipation:
