Heating circuit
A heating circuit is a sealed unvented circuit that con-
nects the heat generator and radiators, in which the
heating water circulates.
A system may comprise several heating circuits.
For example, one heating circuit for the rooms occu-
pied by you and one heating circuit for the rooms of a
separate apartment.
Heating circuit pump
Circulation pump for circulating the heating water in
the heating circuit
Mixer
Hot heating water from the heat generator is mixed
with cooled heating water from the heating circuit. The
heating water, thus brought to the required tempera-
ture, is pumped to the heating circuit by the heating cir-
cuit pump. The control unit adjusts the flow tempera-
ture via the mixer to suit different conditions, e.g.
changing outside temperatures.
Night setback
See "Reduced heating mode"
Open flue operation
The combustion air is drawn from the room where the
heat generator is installed.
Room sealed operation
The combustion air is drawn from outside the building.
Room temperature
■
Standard room temperature or comfort room temper-
ature:
Set the standard room temperature or comfort room
temperature for periods when you are at home dur-
ing 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".
Set temperature
Specific temperature that should be reached, e.g. set
DHW temperature.
Weather-compensated heating mode
