Hybrid hydronic boiler applications Condensing and non-condensing boiler plant System and boiler pump and valve control Domestic hot water control Draft damper start interlock Data logging Modbus communications to BMS Outdoor reset capability The Hydronic System Control is a PLC based boiler sequencing and modulation control for hydronic heating applications. It works with condensing, non-condensing, and hybrid applications to deliver required building heat while saving on fuel. By controlling the condensing and non-condensing boilers using independent PID loop control, the HSC can optimize boiler operation based on the unique characteristics of each boiler type resulting in maximum system efficiency. Hybrid boiler applications System pump, boiler pump and 3-way valve modulation control Domestic hot water control Damper/draft boiler start interlock Modbus communications to energy management system The core design allows for control of multiple hot water boilers in any combination of size and type, and extends to control and optimize the use of condensing, non-condensing, and hybrid boiler systems. This allows management of a heating load as the control calculates independent PID loop for the condensing and non-condensing boilers, respectively. The control uses the monitored system variables to select and operate the appropriate boiler or boilers from operating groups or banks of boilers. This approach optimizes boiler and boiler system efficiency and equipment life The system incorporates thermal shock routines to protect the non-condensing boilers by pre-heating incoming water to keep the inlet to the non-condensing above the required minimum temperature.
