Terminology
Constant Temperature Operation
In constant temperature operation, the heating water
is constantly heated to the selected boiler water
temperature.
Heating Program
With the heating program you determine whether you
heat your rooms and DHW, or only heat DHW, or whether
you shut down your heating system with frost protection
monitoring.
You can select the following heating programs:
" w "
The rooms are heated and DHW is provided
(winter mode).
" w "
DHW is provided but there is no central heating
(summer mode).
"9"
Frost protection for the boiler and DHW tank is active,
no central heating, no DHW heating (standby mode).
Note: A heating program for central heating without DHW
heating is not available. If rooms are to be heated,
hot water is generally also required (winter mode).
If you just want central heating, select the "
heating program and set the DHW temperature
to 50°F (10°C) (see page 10). This means that
you will not heat DHW unnecessarily, but frost
protection of the DHW tank is ensured.
Heating Circuit
A heating circuit is a sealed circuit between the boiler
and radiators, in which the heating water circulates.
Heating Circuit Pump
Circulation pump for the circulation of the heating
water in the heating circuit.
Actual Temperature
Current temperature at the time of the scan;
e.g. actual DHW temperature.
Boiler Water Temperature
See "Constant temperature operation".
18
Open Flue Operation
The combustion air is drawn from the room where the
boiler is installed.
Balanced Flue Operation
The combustion air is drawn from outside the building.
Safety Valve
A safety device that must be installed by your heating
contractor in the cold water pipe. The safety valve opens
automatically to prevent excess pressure in the DHW
tank.
Set Temperature
Default temperature that should be reached;
e.g. set DHW temperature.
Summer Mode
Heating program "
At warmer times of the year, i.e. when the rooms do not
have to be heated, you can stop heating mode. The boiler
remains operational for DHW heating.
DHW Pump
w "
Circulation pump for heating the DHW in the DHW tank.
Drinking Water Filter
A device that removes solids from the water. The drinking
water filter is installed in the cold water pipe upstream of
the DHW tank or the instantaneous water heater.
