Control types
•
With
weather-compensated control
only summer mode,
setback mode (depending on the selected setback type),
DHW priority or adjustment of the outside temperature
(through reduced heat energy demand due to good thermal
insulation) can lead to a switching-off of the heating pump.
– The room influence can be set in the
Set heating curve
menu. The room influence affects both weather-
compensated control types.
–
Outdoor-temp.-compensated
(Default setting)
–
Outside temp. with low end
:
•
With
room temperature-dependent control
the heating
reacts directly to changes of the required or measured
room temperature.
–
Room-temp.-compensated
: The room temperature is
controlled by an adaptation of the flow temperature.
This control behaviour is suitable for apartments and
buildings with major load fluctuations.
–
Room temperature output
: The room temperature is
controlled by an adaptation of the heat output of the
heat source. This control behaviour is suitable for
apartments and buildings with minor load fluctuations
(e.g. open-plan houses). This control type is only
possible in heating systems with one heating circuit
(heating circuit 1) without MM 100/MM 200 heating
circuit module.
•
Ctrl type h. circ. 1
>
Constant
: The flow temperature in
the selected heating circuit is independent from the
outside and room temperature. The available setting
options in the corresponding heating circuit are highly
limited. Setback type and holiday function, for example,
are not available. Settings for a constant heating circuit are
only possible via the service menu. The constant heating
serves to supply heat to a swimming pool or a ventilation
unit.
– Heat is supplied only if
On
(constant heating circuit
permanently heated) or
Auto
(constant heating circuit,
heated at times according to a time program) is
selected as operating mode and if a heat requirement is
present at the MM 100/MM 200 module via the MD1
connection.
If one of the two conditions is not fulfilled, the constant
heating circuit is off.
– A heating circuit, for which
Ctrl type h. circ. 1
>
Constant
is set, is not displayed in the standard
display.
– To operate the constant heating circuit without time
program the operating mode must be set to
(permanent)
On
or (permanent)
Off
.
Pump economy
mode
Yes
Optimised pump operation active: The heating pump runs as little as possible
when dependent on the burner operation (available only with Ctrl type h. circ. 1
Room-temp.-compensated). When the burner stops the pump switches off after
the overrun period (Pump run-on time).
No
If the system has more than one heat source installed (e. g. a solar system or a
hybrid system) or a buffer cylinder is installed, this function
must be deactivated
.
Open-window
detection
On
If the room temperature suddenly drops when venting with completely opened
windows, the room temperature measured before the drop in the temperature
remains valid for one hour in the affected heating circuit. This prevents
unnecessary heating spikes.
Off
No open window detection (only possible with “room temperature-dependent”
control)
PID charact.
(only with room
temperature-
dependent
control)
fast
Fast control characteristics, e. g. when the installed heat output is high and/or in
the case of high operating temperatures and a small heating water quantity
medium
Medium control characteristics, e. g. with radiator heating (moderate heating
water quantity) and medium operating temperatures
slow
Slow control characteristics, e.g. with underfloor heating system (large heating
water quantity) and low operating temperatures

System damage!
In case of non-observance of the permissible
operating temperatures of plastic pipes (on
the secondary side) system parts can be
damaged.
▶ Do not exceed the permissible set value.
