P=64 I=0
Setting the P term to 64 and the I term to 0, calibrates the controllers output to start giving current ( at the I Min
setting % ) at the ‘set point’ temperature and to be at 100% output current ( I max setting % ) at the ‘Overtemp’
temperature. This relationship is linear and ( depending on whether positive or negative logic is applied ) at 100%
controller output, the fan will be going at the fastest speed possible.
