Activation offset with regulation of the neutral zone
When the controlled temperature (coming from neutral zone) enters the
compressors activation zone the compressors/capacity steps are enabled
only if the variable exceeds (in cooling) or drops below (in heating) the
relevant threshold for at least ST30.

Activation delay with regulation of the neutral zone
The controlled variable must be over (in cooling) or under (in heating) the
above mentioned activation level for at least the ST30 time before the
compressor/capacity step is switched ON.

Deactivation offset with regulation of the neutral zone
When the controlled temperature (coming from neutral zone) enters the
compressors disabling zone the compressors/capacity steps are disabled
only if the variable drops below (in cooling) or exceeds(in heating) the
relevant threshold of at least ST32.
