Setting temperature limits Tih and Til
This function is used to set temperature limits Tih and Til. The temperature
limits limit the set temperature. A warning is issued if the internal actual
temperature is outside the temperature limits. These temperature limits
should reflect the limits of your application. A tolerance of 2 K should
also be added to the upper and lower temperature limits to compensate
for overshooting by the control, in particular external controls. The working
temperature range of the heat transfer liquid must also be taken into consid-
eration when defining temperature limits.
