Bosch commerical boiler control

Bosch Thermotechnology’s Heatronic 4000 commercial boiler control can activate up to four condensing and non-condensing boilers utilizing outdoor temperature reset, space heating set point and domestic hot water set point or communication received via BACnet and Modbus. Each boiler in the menu selector comes with 22 default preprogrammed parameters stored in memory. Parameters include fuel type, burner signal (single-stage, two-stage or modulating), boiler mass, low and high inputs in Btu and a min-max modulation signal.
