Tolerance range settings

In this menu you can define for temperature and pressure the deviation between the actual value and
setpoint, 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 delay times for these alarms.
This function only activates after the set-point has been reached once.
