Does not work for 120V or less. Does not work on 24VDC (description incorrect).
1 of 1 found this helpful After testing this product with a variac to control input between 0 and 140 VAC, I've discovered some very annoying issues with 110/120V operation - it doesn't work. I also note that the original description says it will run from 24 VDC and it does NOT. That is an ordering option as I'm now finding out.
I found that with the included K thermocouple and powered up, it wants at least 115V to provide a good reading. Below about 110V you will get strange screen messages. While the manual says it should work to 100V, that is only a minor annoyance. However down around 110V-120V range the reading from the K probe will be LOW. I've seen from -5C to 25C with 25C real temperature. But the news gets worse. Hooked up the SSR and when off it works as described - when ON, the minimum input to the unit rises to 125 VAC - in which case now at 120V your K temperature reading is now randomly changing somewhere between -5 and 25C. I tended to see about 10C so the output stays on. This means it fails UNSAFE for 110/120V heating operaton- the outut will go on, the temperature input will drop, and it will think it needs to say on. It is a bad positive feedback loop. I do NOT recommend this at 110/120V. I would rate less stars but the title of the description says 220V (though the manual and text says otherwise).
Other notes, yes the manual included is useless, download it from the web. The remaining items seem good, nice probe, SSR and heat sink, but be warned no screws were included to mount it to the SSR- not a big deal, but worth noting.
