THERM Hysteresis
THERM hysteresis on a particular channel is configured
via
the
hysteresis
settings
(Register 0x6D
and
Register 0x6E). For example, setting hysteresis on the
Remote 1 channel also sets the hysteresis on Remote 1
THERM.
Hysteresis Registers
Register 0x6D, Remote 1, Local Temperature Hysteresis
[7:4], Remote 1 temperature hysteresis (4
°C default).
[3:0], Local temperature hysteresis (4
°C default).
Register 0x6E, Remote 2 Temperature Hysteresis
[7:4], Remote 2 temperature hysteresis (4
°C default).
Because each hysteresis setting is four bits, hysteresis
values are programmable from 1
°C to 15°C. It is not
recommended to program hysteresis values to 0
°C, because
this disables hysteresis. In effect, this causes the fans to cycle
(during a THERM event) between normal speed and 100%
speed, or, while operating close to TMIN, between normal
speed and off, creating unsettling acoustic noise.
