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.

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).

The MC101 features an automated tuning algorithm. This system calculates the perfect P, I, and d mathematical coefficients for your unique thermal environment.

If you are looking to expand your setup or replace a unit, you can find the Sinotimer MC101 series and compatible K-type thermocouples directly from industrial retailers or sites like Amazon .

Press and hold (or MODE + < ) for 3 seconds until "COD" or a parameter code appears. Auto-Tuning

A: The Relay output (Terminals 3, 4, 5) is a mechanical switch, suitable for directly controlling high-power AC loads like a heating element. The SSR output (Terminals 11, 12) provides a low-voltage DC signal to drive a Solid-State Relay, which is ideal for applications requiring silent operation or frequent, high-speed switching.
