31 Target Rotation Speed
Normal fan motor rotation speed set with the first two
digits for 4-digit numbers and the first digit for 3-digit
numbers.
e.g. 1600 r/min = "16", 800 r/min = "8"
32 Low Speed Rotation Temperature
Condition to decrease target fan motor rotation
speed. When ambient temperature reaches down
to low speed rotation temperature (CB Setting 32),
target rotation speed is decreased by low speed
rotation rate (CB Setting 33).
33 Low Speed Rotation Rate
Percentage against target rotation speed (CB Setting
31).
34 High Speed Rotation Temperature
Condition to increase target fan motor rotation speed.
When ambient temperature reaches up to high speed
rotation temperature (CB Setting 34), target rotation
