ACCESSORIES
Domestic Water Storage Tank
AERCO storage tanks are ASME certified glass-lined pressure vessels designed for use with instantaneous water heaters. When contending with challenging applications they assure consistent hot water service during peak demands. The AERCO storage tanks are available in stratified or accumulator storage configurations.
CONTROLS
Communications Gateway
Optional accessory supports integration with BACnet, LonWorks and N2 systems. Available only for heaters equipped with Modbus control board.
Dry Contacts
Optional for remote "High Limit Tripped Status" indication.
Electronic Controls
AERCO's exclusive electronic control system combines a control box assembly with all circuitry, a flow meter installed at the cold water inlet for feed-forward sensing, feedback sensors and voltage regulator. To maintain optimal temperature control, the system utilizes PID algorithms to monitor outlet temperature and change control valve position. Easy-to-use digital displays are protected by clear-cover enclosure which can be locked. The system also includes an overtemp limit switch and water solenoid valve to function as a secondary water relief valve in an over-temperature condition.
Modbus Communications
Optional control board supports remote control and integration via Modbus protocol to Building Automation or Energy Management Software via RS-232 or RS-485 port.
Pneumatic Controls
AERCO's exclusive Loadalert system continuously monitors water temperature and flow and modulates the flow of steam through the control valve and into the coils. Control panel includes pneumatic controller and dual solenoid valve over-temperature limit system. (One solenoid to disable steam control valve; One solenoid to perform as a secondary water relief valve.) Power on/tripped status lights, liquid-filled remote capillary thermometer and compound steam pressure gauge also included.
