The printed Sinotimer MC101 manual states that the internal Ni-MH rechargeable battery should last approximately 3 years. If the timer loses its settings immediately after a power cut (within 1 hour), the battery is failing.
To replace the battery (Advanced users only):
Note: Most users simply buy a new MC101 unit, as they are affordable.
Forget the confusing flow chart. Here is the simple button logic:
The Sinotimer MC101 manual might look intimidating at first glance, but once you understand the three-button logic, the 10 functions become incredibly powerful tools. Whether you need a simple delay-off for a ventilation fan (F-2) or a complex cyclic timer for a blinking warning light (F-3), this $15 device can replace expensive PLC timers.

Title: SinoTimer MC-101 Manual: Decoding the 12V Delay Relay Module
Posted by: The DIY Automation Guy Date: October 26, 2023
If you’ve just unboxed a small blue module labeled SinoTimer MC-101, you might be staring at a 12V relay with six terminals and a tiny red LED display, wondering, “How do I actually make this thing work?”
You aren't alone. The manual that comes with the MC-101 is notoriously small print and heavy on "Chinglish." Whether you bought this for a car audio delay, a PLC replacement, or a water pump timer, here is the practical breakdown of the SinoTimer MC-101 manual that actually makes sense.
The Sinotimer MC101 allows for 16 different switching events (Programs 1 through 16). Each program consists of an "ON" time and an "OFF" time. For example, Program 1: ON at 06:00; OFF at 09:00.
Step-by-Step Programming:
2 ON.16 OFF.Pro Tip: If you only need 3 schedules, simply leave the remaining programs blank. The timer ignores unused programs.
