NOTE: If the fan has been operating using fan control
mode, and then the ALARM 1 SIGNAL is changed in the GUI
from a “FAN CONTROL” mode to “SWITCH WITH ALARM”
and then back to a “FAN CONTROL” mode, the controller
will not repeat the FAN DELAY cycle of 100% duty cycle
NOTE: Remember that a 0 to 100% span in “PWM Output%
to Fan” does not necessarily correlate to a 0 to 100% span
of the fan’s rotational speed. Many fans will still rotate
even when the PWM fan signal is at 0 %. A typical
relationship of PWM Output% to Fan versus rotational
speed is depicted in the graph to the left.
FAN OPERATION, HEAT MODE FAN OFF
FAN PWM % MAXIMUM OUTPUT 100 %
FAN PWM % MINIMUM OUTPUT 50 %
INCREASE FAN SPEED STARTING AT 70 %
