same way as described in chapter

Only if a value input has been made it can be
switched over to negative
(-) values.
13.6 Setting temperature limit values
The setting range of the operating temperature of the circula-
tor can be limited if the application or the flash point of the
selected heat transfer liquid requires this.
!
This is not a safety element but merely an aid to
help avoid
user faults when operating the unit. The
excess temperature protection must be set sepa-
rately.
When in the external control mode (for EXTERNAL setting
see chapter
13.2), the limits set restrict the temperature in
the circulator's own bath in order to guarantee
a higher
degree of safety against unintentional heating up or cooling
down.
a Select T-SELECT and then LIMIT. Alter the display in

First HIGH and then LOW-LIMIT.
If the HIGH-LIMIT value is lower than the set tempe-
rature value, the set value is decreased according
to the HIGH-LIMIT value.
