12. Tolerance range settings
In this menu you can define for temperature and humidity the deviation between the actual value and set-
point, which that shall cause a tolerance range alarm. The entered value defines the limit of permitted
deviations 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 “Humidity range” is displayed in Normal display (chap. 13.1). If the
alarm buzzer is activated (chap. 13.2) there is an audible alert.
This function only activates after the set-point has been reached once.
