the deviation between the actual value and setpoint,
which that shall cause a tolerance range alarm. The entered value defines the limit of permitted devia-
tions from the set-point (exceeding and falling below). Reaching this limit triggers tolerance alarm.
In addition you can specify a delay time for this alarm.
If there are any actual values outside the tolerance range, after the configured alarm delay time the alarm
message “Temperature range” and / or “CO2 range” is displayed in Normal display (chap. 15.1). If the
alarm buzzer is activated (chap. 15.3) there is an audible alert.
This function only activates after the set-point has been reached once.
Required access level: “Admin”.
