AERCO International, a leading supplier of commercial boilers and water-heating products, introduces two AERCO Boiler Valve Controllers that can help reduce energy consumption and operating costs of variable-flow heating systems. Designed for use with the AERCO Benchmark and KC1000 boilers, the boiler valve controllers automatically sequence each motor operated valve (MOV), so that minimum system flow requirements are reduced to that of a single boiler.

AERCO has designed the boiler valve controllers with a time delay function to eliminate the temperature faults of isolated boilers. Programmable from 1-30 minutes, the function allows residual heat to be absorbed into the heating system prior to closing the boiler isolation valve. If a boiler is firing, the corresponding valve cannot be moved to the “CLOSED” position to avoid temperature overshoot. When system demand is satisfied, the boiler valve controller opens all MOVs to prevent system pump dead head conditions.

Two valve controllers – for 4- and 12-boiler systems – are available. Both feature user-friendly PLC controls to simplify system set up. Operation can be done through the 3”, high-contrast digital display, which also makes it easy to view settings.
