2. With preliminary Test:
To achieve the best control results, select
With preliminary Test
in the controller
settings. The control parameters will be identified within the limits of the min. and max.
set-points. Temperature control will also take place at the set-point limits. Please be
sure to have set these correctly. Depending on the temperature range, the parameter
search will last correspondingly long.
3. Estimate Control parameters:
In comparison to other temperature control devices on the market which have a fixed
control parameter set, we do however offer an additional feature: an estimated control
parameter, which by selecting the thermal fluid and quantity, then using one of the
parameter sets estimated for your application.
Control dynamics
After the control parameters are detected, control dynamics may be changed (see
example below) without making new identification.
You can select between faster regulation behaviour with a small overshoot (submenu
point
Fast, small OS
) and a slower regulation behaviour without overshoot (submenu
point
Without overshoot
). The default setting is
“Fast, small OS”.
The statement
without overshoot only applies where any interfering action is small.

The illustration above shows the transient response for change of set-point.
Note, that you can change the regulation behaviour at any time without having to make
a new controller parameter detection.
