GENERAL
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.
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.
