The Sinotimer MC101 manual, true to the brand’s industrial focus, prioritizes function over flair. In its physical form (when included with new units), it is a slim, staple-bound booklet of roughly 12 to 16 pages, printed on durable, slightly glossy paper to withstand workshop or panel environments. Increasingly, the manual is provided as a PDF download from Sinotimer’s official website or distributor portals. This digital version is searchable, zoomable, and often bookmarked—essential for engineers referencing specific parameters mid-project.
Most MC101 models switch only the Live wire. The Neutral is usually passed through directly to the load.

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.
If you’ve lost control of the settings, perform a hard reset:
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.
