
.
Sets the hysteresis on the alarm temperature between 1 and 20 °C (default 5 °C).
For example, if a given alarm threshold is set to 120 °C and the hysteresis at 5 °C, DQ61 signal an alarm
when the temperature exceeds 120 °C and will continue to report it until the temperature drops below 115
°C

.
Sets the time in seconds (between 0 and 120, default 0) for which the alarm condition must persist before
an alarm is reported. For example, if this parameter is set to 60 sec., raise in temperature above the
thresholds set for periods of less than 60 seconds will not give the alarm.

.
If set to YES (default NO), once in the conditions for which the alarm TRIP is activated, this alarm (alarm
LED on the display and relay contact A3) continues to exist even if the temperature returns to normal until
the key

is not pressed by an operator.

.
This parameter allows you to set the time for which the relay contact A3 (TRIP) is activated in case of
alarm: if it is set to 0 (default), the relay is activated as long as the alarm condition persists, but if you set a
value between 1 and 120 seconds, in case of alarm TRIP the relay will be activated only for that time even
if the alarm condition persists. This function, if the value is not 0, takes precedence over latching function.

.
This feature allows you to disable the alarm activation derived from probe 4. If the probe is connected its
temperature is still shown on the display, but if it is absent, no alarms are reported. The alarm condition is
signaled disabled on the display in the status line.
