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 Switchª 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.
