Pumps
Make the circulation pump settings in this menu (
Chapter 4.1.2).
External
If used, do the settings for external connections in this
connections
menu ( Chapter 4.1.3).
Fuse size
If change needed after commissioning, set the main fuse
size for the house.
Manual defrosting [Yes]: The heat pump is forced to defrost the evaporator.
Smart grid
If used, do the settings for the smart grid in this menu (
Chapter 4.1.4).
PV system
If used, do the settings for the PV system in this menu (
Chapter 4.1.5).
Fixed temperature Use this setting if a buffer cylinder with integrated DHW
heating is installed. The heat pump will heat the cylinder to
a set temperature independent of outdoor temperature. All
heating circuits must be controlled by mixing valves.
Central fault
[All faults and messages]: All faults and messages
indicated will be displayed.
[Only faults]: Only faults indicated will be displayed.
Low-noise
[Silent mode on]
operation
• [No]: The heat pump will always run in normal
operation.
• [Auto]: The heat pump will run in low noise mode
during the set time period.
• [On]: The heat pump will always run in low noise mode.
If [Auto] is activated the heat pump will run in reduced
sound operation during the set time period.
• [Low-noise operation of]: set the start time for the low
noise operation.
• [Low-noise operation until]: set the stop time for the
low noise operation.
• [Min. outside temp.]: Below this outdoor temperature
the heat pump switches over to normal operation.

Prim. heating
[Automatic]: The primary circulation pump is in operation
pump mode
when any heat source is active. When all heat sources are
off, the circulation pump is also off.
[On]: The primary circulation pump is in operation
continuously.
Minimum flow rate The heat pump only starts once the minimum flow rate has
been reached.
Flow rate detect.
[On]: activates the flow control.
[Off]: deactivates the flow control.

Menu: External connections
Make the specific settings for each external connection in this menu.
Multiple settings is possible in each menu.

smart grid function is automatically activated for External connection 4
and no other settings can then be done in that menu.
