Intellidyne The Power to Save


Light Commercial Steam Heating System Energy Economizer

 IntelliCon LCS 1120

The LCS is a microprocessor-controlled, fuel-saving device for light-commercial steam heating systems rated up to 2.5 mm BTU/hr. The LCS reduces fuel consumption, wear on parts, flue emissions and electrical usage, when installed on any new or existing gas, propane, or oil burner. The LCS saves energy by adjusting the burner run pattern to match the system’s “heat load.” Its action is similar to the industry-accepted method of “outdoor-air temperature reset control,” but does not require an outdoor-air temperature sensor or the need to profile the building in order to adjust the “reset” controller properly. The LCS determines the “heat load” by using an easily installed pressure sensor that monitors the boiler’s steam-pressure and the rate that this pressure is changing.
