PROGRAMMING
TRANSITION TEMPERATURE SETTING
Adjusts the transition threshold between the fan
speeds in the AUTO Mode temperature triggers.
Press the up or down button to cycle through 0°F to
8°F (0°C to 4°C) and set a transition threshold. The
fan speed will be set one level above the OFF Mode
speed when the sensor temperature first meets or
exceeds the high temperature trigger. For every
transition threshold crossed, the fan speed will ramp
up by one speed level, up until it reaches the speed
set in ON Mode.
In this example, your high temperature trigger is
set at 80°F, the OFF Mode speed is 0, and the ON
Mode speed is 6. If the transition threshold is set to
0°F, then the fan will trigger to run at speed 6 when
the sensor temperature meets or exceeds 80°F.
However, if the transition threshold is set to 2°F,
then the fan will trigger to run at speed 1 when it
meets or exceeds 80°F. It will then step up to speed
2 when meeting or exceeding 82°F, speed 3 at 84°F,
speed 4 at 86°F, and speed 5 at 88°F. From 90°F
on, it will run at speed 6, the speed set in ON Mode.
