Each program begins with the segment "Start". It defines at which temperature Segment 1 is to
continue the program. It is not possible to specify a time for the Start segment. For thermostats
without cooling ability, the start temperature must be selected higher than the bath temperature,
which prevails before the program start. Without the Start segment, Segment 1 would be
different depending on the bath temperature at the start of the program.

been entered, so that the desired time of ten minutes is maintained even with settling action .
ramps which lie close to the maximum possible heating or cooling rates of the thermostat may be
severely delayed by a tolerance range that is too tight (here in Segment 2) .

Example for the influence of the tolerance field input in
case of external bath temperature control:
The setpoint temperature of the programmer is shown in
grey.
The actual temperature in the external bath container is
represented as a continuous line.
