Bosch’s Heatronic 4000 commercial boiler control can activate up to four condensing and noncondensing boilers utilizing outdoor temperature reset, space-heating setpoint and domestic hot water setpoint or communication received via BACnet and Modbus. Each boiler in the Menu Selector comes with 22 default preprogrammed parameters stored in memory — fuel type, burner signal (single-stage, two-stage or modulating), boiler mass, low and high inputs in Btu, a min-max modulation signal and more. It comes with English and French manuals, an outdoor sensor and five universal sensors.
