Each heat generator has its own control unit
(Vitotronic 100). One control unit regulates and moni-
tors the entire system (Vitotronic 300).
Mixer
Hot heating water from the boiler is mixed with cooled
heating water from the heating circuit. The heating
water, thus brought to the required temperature, is
pumped to the heating circuit by the heating circuit
pump. The control unit adjusts the flow temperature via
the mixer to suit different conditions, e.g. changing out-
side temperatures.
Night setback
See "Reduced heating mode"
Open flue operation
The combustion air is drawn from the room where the
boiler is installed.
Room sealed operation
The combustion air is drawn from outside the building.
Room temperature
■ Standard room temperature:
Set the standard room temperature for periods when
you are at home during the day.
■ Reduced room temperature:
For periods when you will be absent or during the
night, set the reduced room temperature; see "Heat-
ing mode".
Safety valve
Safety equipment that must be installed in the cold
water pipe by your contractor. The safety valve opens
automatically to prevent excess pressure in the DHW
cylinder. The heating circuits are also equipped with safety
valves.
Solar circuit pump
In conjunction with solar thermal systems. The solar circuit pump delivers the cooled heat transfer
medium from the indirect coil of the DHW cylinder to
the solar collectors.
Set temperature
See "Set temperature".
