PRODUCT DATA
FEATURES
• L4006, 7, and 8 provide Spst switching for high or low
limit or circulator control.
• L4006G includes two Spst switches that provide high
limit and circulator control.
• L4006,7; L6006,7 models are available for insertion in:
vertical or horizontal immersion well, vertical or
horizontal direct immersion, and surface mounting.
• L4008, L6008 include remote bulb for mounting
controller at a location away from the sensing element.
• Totally enclosed Micro Switch™ snap-acting switches
operate on temperature rise to set point.
• Models calibrated for high limit use are also suitable
for low limit control if a separate high limit controller
is used.
• Visible control point scale and external adjustment
screw, permit easy setting.
• Remote bulb models may be used to sense air
temperature in ducts and in outside air sensing
applications.
Aquastat® Controllers are immersion type devices for limiting
or regulating the temperature of liquids in boilers, storage
tanks, and other applications where temperature control is
required.

SPECIFICATIONS
IMPORTANT
The specifications given in this publication do not
include normal manufacturing tolerances. Therefore,
this unit may not exactly match the listed
specifications. Also, this product is tested and
calibrated under closely controlled conditions, and
some minor differences in performance can be
expected if those conditions are changed.
