The Boiler Control 270 is designed to operate a single modulating boiler using Outdoor Temperature Reset. It can be used in applications ranging from baseboard or radiant heating systems, to combination radiant and DHW systems. This control regulates a single heating water temperature through Outdoor Temperature Reset and/or setpoint/DHW control. It is capable of controlling a single modulating boiler, as well as the system pump.
