Temperature alarms on ISC-007BW

Your website describes on the alarmsettings of this device:
Alarms for safer: INKBIRD ISC-007BW supports alarms for the set high and low temperatures, once the detected temperature is reaching the set high/low temperature, its alarm will be triggered and a notification will be sent to our mobile phone to alarm us, which is much safer and more efficient for application contexts.

I can’t find how to set the alarm for the lowers temps? If the temp is set for max 180 for example and I set a minimum of 150 immediatly the alarms goes as the temp is higher? Can you explain that?

ISC-007BW does not have a low-temperature alarm setting.
Sorry, it had an error due to the website update. I have contacted the relevant colleagues to correct it.
