NOS Honeywell remote bulb Aquastat controller. Part # L4008A. Settings range is from 100 degrees Fahrenheit to
240 degrees Fahrenheit. 120 Volt AC load is 8 amps. 240 volt AC load is 5.1 amps. 5 1/2-foot capillary tube. I believe this was designed for use in a boiler type hot water heating system. Will ship. Cash only. No offers, I think it is a fair price. If the ad is posted I still have it. I take down my ads as soon as items go out the gate. Located in Bronson. Thanks for looking.
