−
In the "Start" line enter in the field "T end
°C" the temperature at which the se-
quence 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.
−
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 which 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.
−
Continue with to the fields
Õ
“Time”
Õ
“Tolerance”. See program example in (
þ
7.12.1).
−
If there is no entry in the “Time” field (step change in temperature), the outflow temperature is
approached as quickly as possible. With a time entry the final temperature is obtained exactly
after the time expires (ramp).
−
When passing through a step change in temperature, the entry in the field “Tolerance” defines
how accurately the final temperature is to be attained before the next segment is processed.
When passing along a ramp, the "Tolerance" reflects the maximum distance between the set-
point and actual temperature.
+
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 tolerance range that is too close
can cause undesired delays in the start phase of the ramp.

Then continue with to the pump and
signal output setting.
−
The right-hand part of the entry table
appears as shown on the left.
−
Here, in the "Pump" field, the pump level
and, in the fields "Out 1" to "Out 3", the
contact outputs of the contact mode (ac-
cessory) can be programmed. With the
setting "-------" the starting value is re-
tained which was either set before the
program start or was defined by a previ-
ous segment in the running program.
