AERCO now offers an electronic actuator and controller as a standard configuration for all the company's steam-to-water and water-to-water heaters. For facilities seeking LEEDs accreditation points and those that have taken a building-wide approach to energy efficiency, the new package is fully compatible with Building Automation Software (BAS) or Energy Management Software (EMS) systems via Modbus Open Protocol. Faster and more accurate than pneumatic or mechanical solutions, the electronic controls package delivers exceptionally tight temperature control, even when load changes exceed 50% of total heater capacity. It maintains ±2°F temperature control under constant load conditions and delivers ±4°F temperature control under normal load changes. AERCO.
