Fan Control

Minimum Speed Adjustment

 

 

NOTE:  Factory preset low speed setting is set as low as would be normally acceptable in most installations.  In the event slower low speed setting is desired, read the following additional instructions:

1.      Set the control on low setting and remove knob and cover plate.

2.      Locate minimum speed setting (either on side or front panel of control) and adjust with screwdriver by turning slotted white screw clockwise (to slow speed range) or counter-clockwise (to increase speed range).

3.      Motor will now operate from this preset minimum to full speed.

4.      Do not adjust so fan/motor stops while control is in the “on” position.
