Description
The controller is designed to work with Torin-Safin fan
type MIBR190038 EC3BA090 or similar.
Unlike some controllers, adjusting the maximum setting
does not change or interfere with the minimum setting
and vice-versa.
The maximum and minimum fan speed are
programmable using the two push buttons in conjunction
with the pot. By design it is not possible to set the
maximum fan speed less than the minimum fan speed
or set the maximum and minimum fan speeds closer
than 5%. An LED indicates the setting of the appropriate
speed adjustment is enabled.
The limits can be cleared by pressing and holding both
buttons until the LEDs extinguish.
The fan speed is adjustable using the potentiometer,
which can also be used to mount the PCB to a front
panel. The unit also has 4 x 3.5mm diameter fixing
holes on 32x32mm centres
