S66 Series Electronic Fan Speed Control
The S66 Series Electronic Fan Speed Control is
designed to modulate the speed of single-phase,
permanent split-capacitor motors that have been
approved for speed control by the motor manufacturer.
The S66 permits variable speed control of ventilation
fans in response to a DC input signal. Compatibility
with various VAV Box controllers allows for fan speed
adjustment to meet cfm requirements.

Features and Benefits
120-480 VAC, 50 or 60 Hz Allows for use on a wide range of voltage
Motor Control applications
Built-in Radio Frequency Insulates the S66 from interference from other
Interference (RFI) devices, and deters the S66 from interfering with
Suppression other equipment
Internal Isolation Allows the input signal and low voltage power
Transformer (S66AA Model) supply to utilize the same common
Built-in Transient Protection Exceeds IEEE 587 Standards
Hard Start of Motor Applies 90 to 100% of the line voltage to the
(S66AA Model) motor for a period of 7+3 seconds

O peration
The S66 operates as follows:

!
CAUTION: Equipment Damage Hazard.
Because the S66 is a single
phase control, it may be used
only with single-phase motors
approved by the manufacturer for
speed control applications.
Mounting
• Mount the S66 control with the cooling fins in a
vertical position, making sure that there are no
obstructions restricting or preventing the air flow
through the cooling fins. Maintaining operating
temperatures within the listed specifications is
necessary for proper operation.
Note: For maximum heat dissipation, locate the
S66 where a large amount of air passes
through the cooling fins. For maximum
ambient temperature ratings, refer to the
Specifications table.
• Do not mount the S66 in an area where the control
Figure 3: S66AA Input vs. Output Curve is exposed to excessive heat.
• Mount the S66 where it can be conveniently wired
I nstallation to the power supply and the motor.
The S66 controls may be used with motors that are Adjustments
approved by the manufacturer for speed control
applications and meet the following requirements: All S66 Series Controls come factory set. There are
no field adjustments available.
• Ball-bearing construction
• Service factor of 1.25 or greater
• Low heat rise
• Power factor of 0.7 or greater
!
WARNING: Personal Injury Hazard. All S66
Series Controls are designed for
use only as operating controls.
Where an operating control
failure would result in personal
injury or loss of property, it is the
responsibility of the installer to
add devices (safety, limit controls)
or systems (alarm, supervisory
systems) that protect against, or
warn of, control failure.

Wiring
See Figure 5 and Figure 6 for wiring diagrams. W iring Diagrams
!
WARNING: Personal Injury Hazard. To
avoid possible electrical shock
or damage to equipment,
disconnect power supply before
wiring any connections.
!
CAUTION: Equipment Damage Hazard.
To ensure proper operation, the
S66 must be connected to a
suitable earth ground.
• Make all wiring connections using copper
conductors only.
• Install all wiring to conform to the National Electric
Code and local regulations.
Note: For maximum electrical ratings of the control,
see the Specifications table.

Figure 6: Permanent Split-capacitor Single Phase Connections to the S66AA Fan Speed Control when used on
Three-phase Systems. The S66 and the Single Phase Motor Must be on the Same Phase.
C heckout Procedure R epairs and Replacement
Note: Before applying power, make sure Field repairs must not be made. Replacement
installation and wiring connections are controls are available through local Johnson
according to job specifications. Controls/PENN distributors and the original
equipment manufacturer.
After necessary adjustments and electrical
connections have been made, put the system in
operation and observe at least three complete
operating cycles before leaving the installation.
