Installation sequence
Using the control panel
(cont.)
■
Buffer (only available in buffer mode, only for
type VMN3):
– Output temperature:
The temperature at which the buffer is filled.
– Filling outside the program:
Yes – operation enabled even outside the
schedule. If the temperature is too low,
buffer filling is activated according to the
parameters in the schedule.
No – the cylinder is only filled according to the
schedule.
■
Central heating (only type VMN3):
– Heating curve no. (basic operating mode only):
Heating curve selection
(see chapter
Heating curve
).
Note: The parameter appears when the curve
adjustment is set to "Heating"
[Configuration
> Control > According to curve]
.
– Heating curve offset (basic operating mode only):
Heating curve offset (see chapter
Heating curve
).
Note: The parameter appears when a heating
curve adjustment has been set
[Configuration > Control > According to curve]
.
– Max. flow temp (not available in buffer
mode): Maximum temperature of the heating
circuit.
NOTE: Setting excessively high
temperatures that are not matched to the
building parameters, central heating type
and degree of insulation in the building,
can lead to high running costs, among
other things.
– MAN temperature flow (not available in cylinder
mode): Flow temperature in the system when
operating with fixed parameters (manual setting
of the flow temperature)
[Configuration >
Control > Fixed parameters]
.
– Control (basic operating mode only):
According to heating curve – installation
temperature is calculated from the outside
temperature and room temperature according
to the schedule. Fixed parameters – flow
temperature matches the MAN flow
temperature.
– Outside temperature switched off: The outside
temperature. When the temperature is reached,
the central heating is switched off, regardless of
the room temperature.
– Frost protection:
Yes – if the room temperature in standby
mode falls below 7 °C and the outside
temperature falls below 2 °C, the central
heating is switched on.
No – frost protection switched off.
– Boiler protection:
Yes – if the temperature at the boiler
temperature sensor drops below 5 °C,
the DHW circulation pump is switched
on.
No – protection turned off. In this
configuration, the central heating
installation must be filled with frost-proof
fluid.
■
DHW heating:
Output temp.: Set coil output.
Switched off: DHW function is switched off.
If the DHW function is switched off, it can only be
switched on.
■
DHW circulation:
Yes – DHW circulation pump control is switched on.
No – DHW circulation pump control is switched off.
■
Room temp. (only type VMN3):
– Room sensor
Tr: The room temperature sensor is connected
to the Tr input.
RT: The external room controller is connected
to the RT input. A short circuit of the input with
an external room thermostat causes the central
heating boiler to heat up.
Note: This configuration is not recommended.
If additional heating modules are used, this
configuration is not recommended.
– Tr control: Room temperature control (parameter
not available with room sensor setting RT):
Yes – when the set room temperature is
reached, the central heating is switched
off.
No – no control when room temperature is
exceeded.
– Tr hysteresis: A reduction of the room
temperature by the parameter value causes
Turbo mode to start automatically, i.e. activation
of the heating circuits with the maximum
parameters.
■
Automatic Turbo mode:
– Tr hysteresis: A reduction of the room
temperature by the parameter value causes
Turbo mode to start automatically, i.e. activation
of the heating circuits with the maximum
parameters.
– Cylinder:
Yes – DHW priority is maintained.
No - DHW priority is disabled when
Turbo mode is enabled.
– Switch off: Automatic Turbo mode is switched
off.
■
DHW circulation pump:
– Pump protection: Time in which the pump is
switched on for a short period of time during
a longer idle time (blocking protection).
– Automatic mode:
Yes – operation as required
No – continuous operation.
– Type: Type of pump installed
