Bit No. Name
Read/Write Description
3:0
TH2R
Read/Write
These bits set the temperature range over which AFC operates for the TH2 input. The fan starts
operating at TM and reaches full speed at TM+ TR (where TM is the temperature set by the TMIN
code, and TR is the temperature range set by the TRANGE code).
7:4
TH1R
Read/Write
These bits set the temperature range over which AFC operates for the TH1 or REM2 input. The fan
starts operating at TM and reaches full speed at TM+ TR (where TM is the temperature set by the
TMIN code, and TR is the temperature range set by the TRANGE code).
Remote and Local TRANGE

RMR
Read/Write
Read/Write
These bits set the temperature range over which AFC operates for the local temperature input.
The fan starts operating at TM and reaches full speed at TM + TR (where TM is the temperature set
by the TMIN code, and TR is the temperature ranges set by the TRANGE code).
These bits set the temperature range over which AFC operates for the Remote 1 (D1)
temperature input. The fan starts operating at TM and reaches full speed at TM + TR (where TM is
the temperature set by the TMIN code, and TR is the temperature range set by the TRANGE code).
