Single boiler systems
Vitotronic 100, type GC1B
Digital boiler control unit:
■ For constant boiler water temperature
or
For weather-compensated operation in conjunction with a
Vitocontrol control panel and integral Vitotronic 200-H heating circuit
control unit
or
For weather-compensated operation in conjunction with an external
control unit.
■ For two-stage or modulating burners.
■ With cylinder temperature controller.
■ Control of a cylinder loading system with mixer assembly possible
(only as an alternative to the control of a constant return temperature
raising facility with a regulated 3-way mixing valve).
■ With boiler protection function subject to boiler version.
■ With integral diagnostic system and additional functions.
