In the "Start" line enter in the field "T end
°C" the temperature at which the
sequence is to start (default value is
30°C). A time entry is not possible in the
"Start" segment, because the thermostat
immediately executes Segment 1 on
reaching the start temperature.

Delete single segments (rows) with
Delete .
−
For thermostats without cooling ability,
the setpoint temperature must be
obtainable, i.e. above the bath
temperature displayed at the time of the
program start.
−
Using the cursor keys move the black background to the field, which you would like to change.
It can be edited by pressing the key
(see following pages).
−
The soft key Insert inserts in the marked line a new segment that has a default value taken
from the previous segment with the exception of the Tolerance field. The Tolerance is always
specified as 0.00. All following segment lines will be moved one line downwards.
−
In the above window Segment 1 was created in this way.

−
If there is no entry in the "Time" field, the bath temperature is approached as quickly as
possible. With a time entry the final temperature is obtained exactly after the time expires
(ramp).
−
The entry in the field "Tolerance" field defines how accurately the final temperature is to be
obtained before the next segment is processed.
If the tolerance range has been selected too small, it may be that the program does not
continue, because the required tolerance is never achieved.
External temperature control: Especially with ramps, a too close tolerance range can
cause undesired delays in the start phase of the ramp.

Here, in the "Pump" field, the pump level
and, in the fields "Out 1" to "Out 3", the
contact outputs of the contact mode
(accessory) can be programmed. With
the setting "-------" the starting value is
retained which was either set before the
program start or was defined by a
previous segment in the running
program. Further details are given on the
following pages.
