▶ Do not start the indoor unit if there is a possibility of the heating or
auxiliary heater being frozen.

Control unit

The user interface HPC400 controls max. 4 heating circuits individually
in one of the respective control modes:
• Outdoor-temp.-compensated
– The control unit sets the flow temperature in accordance with an
optimised heating curve.
• Outdoor-temp.-compensated with low end
– The control unit sets the flow temperature in accordance with a
simplified heating curve.
For both control modes, a remote control can be installed in the
reference room to enable it to be influenced by the measured and the
required room temperature. The heating curve is then adapted
correspondingly.
The HPC400 control unit is integrated into the device and cannot be
used as a remote control. Ask your contractor which remote controls are
available.
Rule of thumb for outdoor-temp-compensated control with influence of
room temperature: the thermostatic valves in the reference room (the
room in which the remote control is installed) must be fully open!
Depending on the software version of the user interface, the texts shown
in the display may differ from the texts in these instructions.
The adjustment ranges, default settings and functional scope may differ
from the information in these instructions, depending on the system
installed at the site.
• If 2 or more heating circuits are installed, settings for different
heating circuits are available and are necessary.
• If special system components and modules are installed (e.g.
MS 200 solar module, pool module MP 100), corresponding settings
are available and necessary.
• If certain types of heat source are installed, additional settings may
be available and necessary.

If the display lighting is off, only the lighting goes on when the selector is
pressed for the first time. When the selector is turned and another
control element is pressed at the same time, the lighting is switched on
in addition to the effect described. The descriptions of the steps to be
carried out by the operator in these instructions always assume that the
lighting is activated. If no control element is actuated, the lighting turns
off automatically (after approx. 30 s with the standard display, after
approx. 30 min in the menu, after 24 h in the event of a fault).

The standard display refers only to the displayed heating circuit.
Changing the required room temperature in the standard display only
affects the heating circuit displayed.
