SUPER TRADELINE L4064B
Universal Combination Fan and Limit Controllers
APPLICATION
The L4064B controls the on and off operation of the
heating unit's fan motor and provides high limit control
of the main burner. It is suitable for all types of forced
air heating systems.
The L4064B's bimetal sensing element turns fan on
and off according to plenum temperature.
The L4064B has a manual switch to provide
continuous fan operation, mounting adapters for
replacing competitive devices, adapters for wiring
convenience, and a strain relief bushing for protecting
the wiring from damage due to field abuse.
Limit contacts are suitable for line voltage, low
voltage or millivoltage circuits.
The fan-on timing can vary depending on applied
voltage and switch ambient.

wiring to prevent electrical shock or equipment
damage.
2. When connecting cable or conduit to control,
avoid straining the control case.
Follow furnace or burner manufacturer's
instructions, if available. The L4064B has a
maximum switch temperature of 190

LOCATION
If this is a replacement installation, locate the
L4064 in the same location as the control being
replaced. Sensing tube length should be same as
old control. If this is a new installation, the element
should be installed only by a trained, experienced
service technician according to the furnace
manufacturer's instructions. The element must not
touch any internal part of the furnace.
NOTE:
The electrical rating is at maximum switch
temperature of 190

insulating material or a mounting bracket must be
used.
MOUNTING
The device may be mounted either on the
plenum surface or with a bracket (rigid or swivel).
SURFACE MOUNTING
Hole in plenum should be just large enough to
accommodate the 3/4 in. (19.1 mm) diameter
element tube, Fig. 1. For adequate clearance, a
13/16 in. (20.6 mm) diameter hole is
reccomended.
1. Remove cover by squeezing sides and
pulling off. Insert element in plenum and mark
location of mounting holes. Make sure the case is
snug against the plenum before marking the
mounting screws.
2. Punch or drill holes for mounting screws.
3. Place insulation between plenum and case if
necessary.
4. Fasten controller securely with mounting
screws.
