The differential value has a special meaning, if the proportional and the integral controlling of the
regulator are deactivated. In this case the fan speed will be accelerated or decelerated in levels
according to the differential value and the amplification factor set up.
Amplification factor
The amplification factor multiplies the temperature deviation from the nominal value. An
amplification factor below 1 cause attenuation of control-loop, a value of 1 deactivates the use of
amplification factor.
TDead time (Toff)
The reset time will only have an impact by using integral value and is given in percentage.
According to the control mode through the integral value, if a delay of controlling fans exceeds
the nominal value occur, the smaller is the selected reset time.
