The Model C-05820 provides alternator sequencing logic to automatically fire the boilers as required to meet changing plant conditions. The boilers continue to operate from their own modulation controls. Remote pressure or temperature switches for each boiler provide an input signal for the alterna- tor.
The Cleveland Controls Model C-05820 Boiler Alternator is a simple and economical alternator suitable for any two-or three-boiler installation, operating on either steam pressure or hot water temperature. Modbus communication for interfacing with SCADA or other controls is standard.
