Speed Dial Wiring Diagrams
Mounted Speed Dial
– (See Figure 16) Standard potentiometer speed
dial is mounted and wired at the factory.
For field replacement: Connect the Speed Control Potentiometer to
the motor control as follows:
a. Connect one end of 10K Potentiometer to P10-1 (24VDC).
b. Connect center (wiper) of Potentiometer to P10-2 (Analog Input)
c. Connect other end of Potentiometer to P10-3 (DGND).
Remote Speed Dial**
– (See Figure 17 & 18) Factory mounted
Molex receptacle allows a quick connection to remote potentiome-
ter speed dial. The potentiometer dial can be mounted up to 100 ft
from fan using additional wire by others.*** Speed B on box is not
used for single speed selection and will not have a dial.
Dual Speed Dial**
– (See Figure 19) Factory mounted Molex recepta-
cle that allows a quick connection to Dual Potentiometer Speed Dial.
The supplied unmounted toggle switch will select the Low (LO) or High
(HI) speed on the speed controllers based on the dial settings. Toggle
switch and mounting plate fit in a standard gang box and wired to Dual
Potentiometer Speed Dial. The speed dial can be mounted up to 100 ft
from fan using additional wire by others.***
Building Control 0-10VDC Wire Kit
– (See Figure 20) Factory mount-
ed Molex receptacle that allows a quick connection to supplied 2 wire
connector (wires are 3” long).
**
Disconnects and Speed Dials are available as mounted on certain fan
models and will be wired to motor, for more information see descriptions
on submittals for these items weather they are mounted, not mounted
or not available
