This read-only INTEGER reports the configured low alarm limit for a monitored channel on the TH2E device; the source DESCRIPTION for this specific object is blank, so its role is inferred from its position in the watch-value table alongside limitHi and limitHy. An admin reads this to know the lower threshold value that, when the channel's reading falls below it, would trigger an alarm condition when modeWatch is enabled. For illustration, this object might report 50 as a low-temperature alarm threshold (e.g. 5.0 degrees) for a monitored channel.
