IntelliCon® HW 3250

The IntelliCon® HW+ 3250 is a microprocessor-based, fuel-saving control for hot water (hydronic) heating systems. The HW 3250 reduces fuel consumption, wear on parts, flue emissions and electrical usage, when installed on any new or existing gas or oil burner. The IntelliCon 3250 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 HW+ determines the “heat load” by using an easily installed strap-on temperature sensor that monitors the boiler’s out-flow water temperature and the rate that this temperature is changing.
