Alarm settings worksheet
The alarm settings for the Supra determine which alarm conditions are enabled, which are disabled,
and their settings. All these work together to determine how and when the alarm relay activates (in
other words, signals an alarm condition).

Minimum duration
prevents alarms from activating when the temperature rises or drops for just a
few seconds.

Silencing
temporarily disables an alarm setting after an alarm has been acknowledged. This
prevents the alarm relay from activating immediately after acknowledging the alarm.

Alarm biasing
prevents the alarm from sounding on very hot days when the
temperature set
point
cannot be maintained. The
high temperature bias
is added to the
high temperature
alarm
setting if the outdoor temperature is higher than the alarm setting.
