Lost the original manual? Bookmark this post—and if you need advanced cycling or off‑delay, look for the or MC-103 series. Have a specific MC-101 wiring question? Drop a comment below (or check the tiny diagram on the unit’s side – it’s actually helpful!)
| Switch setting | Range | Resolution | |----------------|-------|-------------| | 0.1S – 99.9S | 0.1s | 0.1 seconds | | 1S – 999S | 1s | 1 second | | 0.1M – 99.9M | 0.1m | 0.1 minutes | | 1M – 999M | 1m | 1 minute | | 0.1H – 99.9H | 0.1h | 0.1 hours | | 1H – 999H | 1h | 1 hour | : The manual isn’t always clear—if your unit doesn’t have DIP switches, hold S for 5 seconds to cycle ranges. Wiring the MC-101 Terminals are labeled 7, 8 for power and 1, 2, 3 for the relay output (common, NC, NO). Check your unit’s side sticker.
