Supply air limitation
When control is being applied to the return air or room air, the supply air temperature can be limited. This limitation is used to avoid
blowing air at too high a temperature in heating mode or too cold a temperature in cooling mode. This limitation is activated by
parameter P156.

Supply air compensation
When control is being applied to the return air or room air, the supply air temperature can be compensated. This compensation is
used avoid blowing air at too cold or too high a temperature when the control is in deadband mode (no heating or cooling requirement
calculated). This compensation is activated by parameter P157.
