Boiler-specific functions
The Vitotronic 100 control unit controls the boiler temperature according to heat demand input (room thermostat connections) or the calculated outdoor reset set point.
Boiler water temperature is limited through the adjustable aquastat. Minimum boiler water temperature protection is achieved with the built-in pump aquastat and the outdoor reset control.
Electronic boiler control
-single boiler systems
-heating circuits without mixing valves
-single and two stage burners
-anolog temperature display
