This register specifies the parameters of the Remote Temperature-Fan Control mode.
Low Temperature Bits: [R-TEMP 4:R-TEMP0]
These bits specify the low temperature of the auto remote temperature-fan control. In this control mode, the duty
cycle is equal to the value of the DCY-LOW-TEMP register when the remote temperature is less than or equal to
the value defined by bits [R-TEMP4:R-TEMP0].
Slope Bits: [R-SLP2:R-SLP0]
These bits define the increment of the duty cycle when the remote temperature rises every 1 ° C in the auto
remote temperature-fan control.
