7.8.3 Defining temperature limits
With this function, it is possible to define a minimum and a maximum temperature in which the
thermostat controls. By reaching the temperature limits, a warning appears. In this way setpoint input
can be prevented which may damage the heat carrier medium or the apparatus. For example, if water is
used as the heat carrier liquid, +95°C would be practicable as the maximum temperature and +5°C as
the minimum temperature.
