AIR CONDITIONING & HEATING CONTROLS 53 Thermostats AQUASTAT CONTROLLERS L4006A1678 Aquastat Controller High or Low Limit Overview 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: Totally enclosed Micro Switch snap-acting switches operate on temperature rise to setpoint. Visible control point scale and external adjustment screw permit easy setting. Horizontal or vertical insertion of the sensing element. Direct or well immersion of the sensing element. Models available for strap-on mounting. Remote bulb model may be used to sense air temperature in ducts and in outside air sensing applications. SOURCE 1 PART NO. DESCRIPTION MLP $ S1-L4006A1678 HIGH OR LOW LIMIT AQUASTAT CONTROLLER 303.09 Immersion-type controllers that combine high limit protection with switching relay control of burner and circulator motors. Features: High limit opens burner circuit only. Include transformer and accessory terminals for adding a remote low limit controller. Case available for horizontal or vertical mounting. Requires a 24 VAC thermostat with heat anticipator set at 0.2A. TRADELINE models include well adapter, tube of heat conductive compound and range stops.
