L6064A
Universal Two Speed Fan and Limit Controllers
APPLICATION
These combination warm air fan and limit controllers
are suitable for all types of forced air heating systems.
The controllers have 2 switches with 3 individually ad-
justable set points. One switch opens the limit circuit if
the plenum temperature exceeds the preset safety limit;
most models reset automatically. The other switch
changes fan speeds. On all the L6064 the fan speed is
switched from low to high and vice versa according to
the plenum temperature. The fan speed is switched to
low if the plenum temperature falls below the fan off set
point. All the L6064 models are intended for use with
conventional warm air systems.
All models may be used as limit controls by wiring only
the limit side.
Limit controls are suitable for line voltage, low volt-
age, or millivoltage circuits.
INSTALLATION
When installing this product...
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazardous
condition.
2. Check the ratings given in the instructions and on
the product to make sure the product is suitable for your

CAUTION
!
1. Disconnect power supply before beginning in-
stallation to prevent electrical shock or equipment
damage.
2. When connecting cable or conduit to control,
avoid straining the control case.
LOCATION
If this is a replacement installation, locate the
L6064 in the same location as the control being re-
placed. The L6064 sensing tube length should be
the same as the old control. If this is a new installa-
tion, the element should be installed only by a
trained, experienced service technician according
to the furnace manufacturer's instructions. The ele-
ment must not touch any internal part of the furnace.
MOUNTING
The device may be mounted as follows:
All models -- Surface or Bracket.
SURFACE MOUNTING
Hole in plenum should be just large enough to
accommodate the 20 mm (3/4 in.) diameter element
tube.
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 holes.
2. Punch or drill holes for mounting screws.
3. Place insulation between plenum and case if
necessary, or use a mounting bracket.
4. Fasten controller securely with mounting
screws.
