4.3.2.2 ONE GROUP OF FANS CONTROLLED BY TWO GROUPS OF SENSORS
When 2# sensor control the same group of fans: the number of output fans are the maximum number
of 2# sensor required fan on.
Fan Automatic Control Setting:
a) The balanced running time is not enable, temp. sensor 1 and temp. sensor 2 control the first group
of fans at the same time, and the outlets of the first group of fans are (Output port 1 2 3 4);
b) The fan control curves of sensor 1 and sensor 2 are as follows: (X1:60

c) The return difference value of sensor 1 and sensor 2: 5

;
d) 2#PWM output temp. sensor selects sensor 2.
Fan Automatic Running Description:
The running process description of turning on/off the fan is the same as 4.3.2.1.
NOTE:
The fan on temperature of sensor 1 or sensor meets the output condition, the fan off temperature of the
sensor 1 and sensor 2 meet the shutdown condition simultaneously. Example: when the temperature of sensor 1 is 70
℃
and the temperature of sensor 2 is 80
℃
, two fans should be output by fan groups; when the temperature of sensor 1
drops to 65
℃
and that of sensor 2 drops to 75
℃
, one fan shall be shut down of fan groups.
NOTE:
In auto mode, when the unit normal input is inactive, delay the setting time, all the output will be disconnected
and the output of PWM duty ratio is 0.
4.3.3
MANUAL MODE
Manual mode is activated by pressing
, the controller enters “Manual Mode” and the LED indicator
is illuminating.
4.3.4
MANUAL CONTROL OUTPUT
a) In manual mode, press
and controller enters manual fan switch mode. Select the
corresponding fan output by pressing
. When select output 1, press
and the outlet 1 will
output, press
and the outlet 1 will be disconnected.
b) In manual mode, press
and controller enters manual fan speed mode. Select the
corresponding speed output channel (PWM) by pressing
. When select PWM1 channel, press
to speed up (1#PWM output duty ratio increases), press
to speed down (1#PWM output duty
ratio decreases).
