Tasmota Thermostat - Control Response

[erniberni]

Hi,
I am working on a project with Tasmota Thermostat.
A small container should be kept on constant temperature which is working up to now quite well.
I am only struggling with the behavior when initial switched on an a big temperature difference must be controlled.
The thermostat swings far above the preset temperature and after that the temperature is controlled very well.
How can I prevent this behavior?
Settings different from default are:
TIMEPICYCLESET 10
PROPBANDSET 4
TIMEMINACTIONSET 1

I'm not using thermostat myself but there are some elements there https://tasmota.github.io/docs/Thermostat/#pi-controller-main-parameters

I feel that the cycle should be reduced, at least for some time after a new target has been given

It looks as if the parameters (I component) have to be adjusted
