FOR VERTICAL MOUNTING AND HORIZONTAL SENSOR INSERTION

FOR SURFACE MOUNTING

GENERAL

WITH REMOTE BULB

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.
