POWERING AND SETUP

10
DAISY CHAIN AND SETUP
The fan controller can power up to two compatible fans to share the same programming. The
compatible fans do not need to be the same model or part of the same product series. Please
see page 4 for compatibility details.
Note that the controller receives power to operate from the fans. The controller only supplies
programming and not power. Each linked fan will still require its own power source.

PROGRAMMING
CONTROLLER MODES
Pressing the mode button will cycle through the controller’s available programming modes: OFF, ON,
AUTO (4 triggers), TIMER TO ON, TIMER TO OFF, CYCLE (On and Off), and SCHEDULE (On and
Off).
ON MODE
Your fan will actively run at the speed set,
regardless of the probe's reading. The ON mode
also serves as the maximum speed setting the
other modes will run in.
OFF MODE
Your fan will not run while in this mode. However,
the fan speed set while in this mode establishes
the minimum speed in the other modes. When the
fan is triggered to turn OFF in all other modes, it
will instead run at the speed set here.
AUTO MODE (HIGH TEMPERATURE TRIGGER)
Pressing the up or down button sets the high
temperature trigger. The fans will activate if the
probe’s reading meets or exceeds this threshold.
Once triggered, the fan will gradually ramp up to the
speed set in ON mode. If the probe’s reading falls
below this trigger point, the fans will gradually slow
down to a stop or at the speed set in OFF mode.
You may set this trigger below the low temperature
trigger to create a specific range in which the fan is
active.
Note that this trigger can activate as long
as you are in AUTO Mode, even if you are
viewing a different trigger within AUTO Mode.
If there is a speed set in OFF Mode other
than zero, the fans will run at that speed when
triggered to turn off.

speed set in ON mode. If the probe’s reading rises
above this trigger point, the fans will gradually slow
down to a stop or at the speed set in OFF mode.
You may set this trigger above the high temperature
trigger to create a specific range in which the fan
is active.
AUTO MODE (HIGH HUMIDITY TRIGGER)
Pressing the up or down button sets the high
humidity trigger. The fans will activate if the probe’s

PROGRAMMING
CALIBRATION TEMPERATURE SETTING
In this setting, adjust the temperature reading
that the sensor probe is measuring. Press the
up or down button to increase or decrease the
data figure by 2°F (or 1°C) increments. The
calibration cycle ranges from -8°F to 8°F (or
-4°C to 4°C) and will be applied to the sensor
probe’s measurements.
CALIBRATION HUMIDITY SETTING
In this setting, adjust the real humidity
reading that the sensor probe is measuring.
Press the up or down button to increase or
decrease the data figure by 1% increments.
The calibration cycle ranges from -8% to
8% and will be applied to the sensor probe’s
measurements.
CLOCK SETTING
In this setting, adjust the current clock time.
Press the up or down button to increase or
decrease the time. Once you cycle through
12:00 each time, the units will automatically
change to AM or PM. The current clock time
will be shown at the top right corner of display.

20
PROGRAMMING
TRANSITION TEMPERATURE SETTING
In this setting, adjust the incremental rules in which
the fan speed ramps up or down for temperature
triggers in AUTO Mode. Press the up or down
button to cycle through 0°F to 8°F (or 0°C to 4°C)
to set a differential increment. Once setup, when
the sensor temperature first meets or exceeds
the high temperature trigger, the speed will start
at one speed above the speed set in OFF Mode.
Then for every differential increment that the sensor
temperature is different from the set temperature,
the speed of the fan will ramp up by one additional
speed level. This continues until the fan reaches the
speed set in ON Mode.
For example, let’s assume your high temperature
trigger is set at 80°F, the speed set in OFF Mode
is 0, and the speed set in ON Mode is 6. If the
differential increment was set to 0°F, then the fan
would have just triggered to run at speed 6 when
the sensor temperature meets or exceeds 80°F.
However, if the differential increment was set to 2°F.
Then the fan would start running at speed 1 when
it meets or exceeds 80°F. Then at speed 2 when
it meets or exceed 82°F. Then at speed 3 when it
meets or exceeds 84°F. Then at speed 4 when it
meets or exceed 86°F. Then at speed 5 when it
meets or exceed 88°F. Then from 90°F or higher, it
will run at speed 6 which was the speed set in ON
Mode.
