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
– Outside temp. with low end: Æ Simple heating curve,
page 38.
Mixer runtime 10 ...120 ... 600 s Elapsed time of mixer in the selected heating circuit
Mixer increase 0 ... 5 ... 20 K Enter heat production increase for mixer
DHW priority Yes DHW heating is activated, the heat requirement of the heating system is
interrupted
No DHW heating is activated, the heat requirement of the heating system is met
simultaneously if hydraulically possible
Shown in standard
display
Yes The selected heating circuit is visible in the standard display. The change
between automatic mode and manual operation in the corresponding
heating circuit is possible from the C 400/C 800 as well (with or without
remote control).
No
The selected heating circuit is not visible in the standard display. The
change between automatic mode and manual operation is not possible. If
there is no remote control installed for the selected heating circuit, settings
can be made as usual through the main menu, e.g. temperature levels of the
operating modes and time programs.
Pump economy
mode
Yes Optimised pump operation active: the heating pump runs as little as
possible depending on the burner operation (available only with Ctrl type h.
circ. 1 Room-temp.-compensated).
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.
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 systems (large
heating water quantity) and low operating temperatures

NOTICE: System damage!
In case of non-observance of the permissible
operating temperatures of plastic pipes (on
the secondary side) system parts can be
damaged.
