6.16 Programmer
6.16.1 Basic information
The programmer allows you to perform and save a temperature-time pro-
gram. A program consists of several temperature-time segments A segment
contains information on the final temperature of the segment, the duration,
the temperature tolerance, the pump level and the switch position (off/on)
of the contactmodule. Ramps, temperature jumps and temperature mainte-
nance phases are possible.
n
Ramp
A ramp is defined by the specified duration between the start and
the end of the segment, and by the destination temperature, i.e. the
temperature at the end of the segment.
n
Temperature jump
If a time is not specified (time is equal to 0), the end temperature is
reached as quickly as possible.
n
Temperature maintenance phase
No temperature change (i.e. the temperatures at the start and the end
of a segment remain identical).
n
Pump level off or 0

Pump level [---] (means pump is off) can be selected within a
segment. As a result, the program ends when this segment is
reached, even though other segments follow in the program. The
status of the thermostat is set to “Standby”. When the program is
started, a message appears indicating that the program will end at
this segment with pump level 0.
n
Program optimization
Activating program optimization yields a very good control action in
practice. With programs including both ramps and other types of seg-
ments, the actual temperature profile matches the target temperature
profile more closely than programs without optimization. It reduces
overshoots. There can only be large undershoots at the ramp ends if the
control parameters are very unfavorable. Deactivate optimization in this
case.
Tolerances that are too small will impair the control result. Work without
tolerances where possible.
n
Standby
If the device switches to standby while a program is running, the active
program is automatically paused.
