1. Set point deviation: Enables/disables set point deviation compensation.
2. Set point deviation activation: Deviation deadband. As long as the actual value does not deviate more than the deadband in
this parameter, the function is not activated.
3. Set point deviation weight: The gain increase is based on the set point deviation compared to nominal, and this ratio is
multiplied by the weight factor.

°C/Gain
The diagram above shows how the reaction to a set point deviation could look.
This situation could be rising cooling water temperature in a genset. Below the set point, the gain is very high, but as the
temperature is getting closer to the set point, it decreases the gain compensation. Within the activation limit, the gain is at nominal
value.
As the temperature keeps rising, it exceeds the activation limit again, and when it is above set point the gain is increased
instantaneously. As the temperature keeps rising, the gain compensation decreases again.
