High Alarm
A high alarm is triggered when the temperature exceeds this set point.
Low Alarm
A low alarm occurs when the temperature is lower than this set point.
Deadband
The deadband (hysteresis) prevents conditions and alarms from triggering excessively when the
measurement value vacillates around the trigger point. With high alarms, the measurement must fall
below the high alarm point minus the dead band before the high alarm will be triggered again. Likewise
the deadband on the low alarm requires the measurement to rise above the low alarm point plus the
deadband before the low alarm will be triggered again.
For example, if the dead band is set to 0.5°C, and a high alarm is set at 13°C - the high alarm will occur
at 13°C; however, it will not turn off until the temperature drops below 12.5°C (13°C - 0.5°C).
Email Option
Simple email messages can be sent in response to alarm conditions. This parameter is used to specify
what alarm conditions, if any, will cause email messages to be sent. Email notifications will work only if
email is correctly setup in the following settings.
No Email Messages: No email messages will be sent due to alarm conditions.
Send Email on High Alarm: Email notifications will be sent due to a High Alarm condition.
Send Email on Low Alarm: Email notifications will be sent due to a Low Alarm condition.
Send Email on High and Low Alarm: Email notifications will be sent due to a High or Low Alarm condition.
Send Email on High, Low and Normal Alarm: Email notifications will be sent due to a High or Low alarm
condition or when Normal conditions are restored.
Email on Low Battery
When a low battery condition occurs an email message is sent to this address. To conserve already
meager energy resources, only one low battery message is sent.
