Before powering on, ensure your connections match the diagram on the side of your specific unit. Terminals for AC power (usually 1 & 2). Sensor: Input terminals for your thermocouple or RTD.
The rocker or button is the source of 50% of user support queries. Here is how it works according to the official manual specifications:
Run the Auto-Tuning cycle again. If you are using a mechanical relay option, ensure your Cycle Period ( T ) parameter is not set too low, which prevents the mechanical relay from switching quickly enough. For fast-cycling systems, convert to a Solid State Relay (SSR).
: Check if the front OUT light is on. If it is on but no heat generates, inspect your external SSR, fuse, or heating element wiring. sinotimer mc101 manual
: Features a dual-display interface showing both the Process Value (PV) (current temperature) and the Set Value (SV) (target temperature). High Accuracy : Measurement accuracy of FS with a maximum resolution of 0.1∘0.1 raised to the composed with power for thermocouples and RTDs.

Relay Output (250V AC / 3A resistive load) — Best for driving contactors or low-power loads. Before powering on, ensure your connections match the
Connect the incoming Hot/Live wire from your main power supply.
Connect the two matching colored wires (usually red or white, showing low resistance between them) to and Terminal 10 .
